SYNTHESIS REFLECTION PAPER
“Something old, something new, something borrowed, something blue!” The
instructional design process is like planning a wedding. Wedding planning entails putting
together several items for several components of the overall wedding. This is much like the
process of instructional design, which has many components that all have to be outlined and
planned. The major events of a wedding include: the engagement, the rehearsal, and the
wedding ceremony. The events correlate with models in the instructional design process. A
wedding planner consults with the bride and critical family members. Important questions will
be asked to gather background information and determine the wants and needs of the bride. This
aligns with the analysis component of instructional design. Wedding planners conduct needs
assessments and plan accordingly. Once the planning is underway, the wedding planner must get
several items together: dresses, tuxedos, decorations, floral arrangements, ministers, the venue,
and much more. An instructional designer must also plan for several items: instructor guide,
learning materials, technology, and assessment tools. The next step is rehearsal. Everything has
been put together, but has to practiced and evaluated to see if any changes must be made before
the big day. In the instructional design process this can be compared to the expert review and
evaluations. The instruction will be rehearsed one-on-one, in a small group setting, with a field
group, and with an expert. The instruction will be modified accordingly. Lastly, the instruction
is implemented. The big day has arrived!
I am currently in the process of planning a wedding and could see the similarities in the
two processes. There are many things included in the processes that are overlooked. I
overlooked all the fine details of instructional design as a classroom teacher. Over the course of
this semester, I learned how detail-oriented the process of designing instruction really was. As a
teacher, new instruction and curriculum is placed in front of me frequently. However, I was
oblivious to the tedious tasks that must be performed in order to design effective instruction.
Examples of components of instructional design that I find challenging as a classroom teacher
include detailed needs assessments, accurate learner descriptions, personally designed learning
materials, expert review, evaluations, and field trials. When I begin each semester, I acquire
very little information about my learners, and information I obtain from them concerning their
needs or backgrounds are not completely accurate. I design quizzes, tests, projects, and other
activities when teaching my classes. However, I rely heavily on my textbook, supplemental
materials, and the fellow mathematics teachers for much of my instruction. Taking the time to
design all of the instruction for my classes would be impossible. As a teacher, I think it would
also be difficult to work with an expert on every single lesson and perform one-to-one, small
group, and field evaluations before teaching every lesson.
Although, I felt that much of the instructional design process would be difficult to
implement as a teacher, there were many components that I felt would help me become a more
effective teacher. As I designed the instruction in the final project, I felt that the instructor guide
was a very useful tool. Classroom teachers have to create lesson plans continually. The
components of the instructor guide as outlined by Smith and Ragan are critical for effective
instruction. Developing lesson plans that include the fifteen parts of instruction catered to the
different types of learning would be extremely beneficial for my learners. While designing the
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT
Copyright © 2010, Vertoria D. Lagroon 5
final design project, I created instruction for a highly procedural lesson. I used an acronym as a
method of employing learning strategies. Prior to the course, I may not have given the lesson
that much thought. However, employing learning strategies during instruction will help me be a
better teacher and my students be more successful.
In the future, I will refer back to the knowledge and skills that I acquired as a result of
this course and apply them in my career as a classroom teacher. I will incorporate the suggested
components of an instructor guide in my lesson plans and future instruction. I will take the time
to plan for ways to employ learning strategies in my lesson, as I feel this is the area in which I
will reap the most benefit as a teacher. Overall, I feel that I learned a lot of valuable information
about instructional design from this course.

PART 1 TOPIC
1A LEARNING GOAL
The students will find the correct solution to a minimum of 7 out of 10 problems
involving solving systems of equations using the elimination method.
1B AUDIENCE DESCRIPTION
The learners for this instructional design project are ninth graders at McCormick High
School located in McCormick, SC. McCormick High is a secondary school within the
McCormick County School District that instructs grades ninth through twelfth.
1C RATIONALE
The topic for this instructional design project was chosen because a need exists for a
more efficient way to teach Algebra topics to ninth graders. Presently, freshmen are enrolling in
Algebra courses in which they have not mastered the prerequisite skills for. Instruction is needed
that will counteract this dilemma and allow mastery of grade-level content.
The instruction will take on a supplantive approach. The supplantive strategies were
elected primarily because the learning goal falls in the field of mathematics, a scaffolding
subject. “A relatively supplantive, didactic, expository approach, rather than a highly generative,
discovery approach, seems to be best for teaching procedures” (Smith & Ragan, 2005). Also, the
learners possess less prior knowledge and a limited repertoire of learning strategies. According
to Smith and Ragan, it is expected that they will be more successful using the supplantive
approach (2005). The design of this instruction will involve much facilitation and prompting for
the learners.
Strategies for procedural learning will be employed. The learning goal involves a
complex procedure that is used under the broad concept of linear equations; therefore the major
instructional strategy is procedural. Solving a system of linear equations is an algorithm with
definite, ordered steps. Similar to most problems in mathematics, the learning goal includes a
series of steps that the problem-solver should take for increased success. The process requires
learners to use decision points while in route of finding the correct solution. Learners will have
to analyze the mathematical situation during many steps and then determine the appropriate next
step to take.

PART 2 ANALYSIS REPORT
2A DESCRIPTION OF THE NEED
Needs Analysis Survey
A needs analysis survey was developed for potential learners to take in order to assess
prior knowledge and prerequisite skills needed to achieve the learning goal. Certain skills are
needed to establish readiness to receive instruction. For this particular learning goal, those skills
are: graphing linear functions, solving multi-step equations, solving equations for a specific
variable, and evaluating expressions. The needs analysis survey consists of 20 questions
addressing the skills mentioned above. See Appendix A.
Needs Analysis Data Report
The results of the needs analysis survey were consistent. Most all survey takers had an
adequate knowledge of evaluating expressions for given variables. However, the learners
performed poorly in the areas of graphing linear functions, solving multi-step equations, and
solving equations for a specific variable. Approximately thirty-one percent of survey takers were
proficient in all prerequisite areas. The results of the needs analysis survey suggest that there is a
need for new instruction.
2B DESCRIPTION OF THE LEARNING CONTEXT
Learning Context
What are the characteristics of the classes and facilities that will use the new instruction?
The instruction for this design project will take place at McCormick High School. The
instruction will occur as a part of five Algebra 1 classes with approximately 12 to 21 students,
taught by a South Carolina certified math teacher. The proposed math teacher to deliver this
instruction has over thirty years teaching experience. This instruction will be merged into the
existing Algebra 1 curriculum, which is adopted from Anderson 5’s curriculum guide.
What hardware is commonly available in the potential learning environments?
Hardware that will be utilized during the delivery of instruction include a SMART
boardTM, LCD projector (Epson EX71 WXGA Multimedia), and a laptop (Dell Latitude E6410).
The following software applications will be used on the laptop: Microsoft Office PowerPoint,
Adobe Reader, Windows Media Player, and Quicktime Movie Player. Students will have access
to a class set of 22 graphing calculators (TI-83+).
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT
Copyright © 2010, Vertoria D. Lagroon 8
What are the characteristics of the school system in which the new instruction will take place?
McCormick High School is a school with the McCormick County School District, whose
mission is to ensure that each student receives a quality education and becomes a productive
citizen by providing an educational environment that utilizes all available resources within our
diverse, rural community surrounded by national forests and lakes. McCormick High School’s
respective mission is teaching and learning through rigor, relevance, and relationships. The
overall goal and expected outcome of this new instruction is to increase the passing rate of the
Algebra 1 end-of-course test (EOC) and High School Assessment Program (HSAP) as well as
strengthen the math department. The new instruction relates to the organizations’ missions in that
it directly corresponds to math instruction and sets to increase learning, which will ultimately
raise standards tests scores. Primary decision makers within the organization include the district
Superintendent, McCormick High School Principal and Assistant Principal, district Director of
Instruction for grades 6th
through 12th
, district Special Needs Coordinator, and the Executive
Director of Finance.
Transfer Context
The learning goal of solving systems of linear equations has many applications or real-
world uses. A specific application that will be relevant for the learners is calculating the best
cell-phone plan or coverage provider. Oftentimes, mobile plans will have a base rate for a
definite amount of minutes and then a rate for every minute beyond your plan’s limit. Equations
can be written to algebraically express the terms of these plans. When these systems of
equations are solved, the solution gives us the point where the price of the plans is the same.
From the solution, one can infer which plan is the better deal or which one gives you the most
minutes for your money. As the learners are statistically great communicators and mobile phone
users, having this skill can potentially save them a lot of money in the future.

Prices of all types of companies can be compared through solving systems of linear
equations. Learners can transfer context through determining which car rental company to use in
an emergency. Much like the cell phone coverage example, learners can write equations to
express the company’s rates and then find the solution. Other applications include: profit,
motion, and work problems.
Description of the Learners
The learners will be incoming freshmen, ranging from 13 to 15 years of age.
Approximately 88% of the learners are Black, non-Hispanic which is forty-nine percent higher
than the state average. The remaining 12% are White, non-Hispanic which is forty-one percent
below the state average. Sixty-seven percent of the learners are eligible for free or reduced
lunch. This information was provided by the school district.
Learners were given a survey that addressed more socio-economic demographics, such as
household size and highest educational level attained by parents or guardians. The survey was
also used to determine their attitudes towards mathematics and their recent experiences in
mathematic courses. Questions were asked about instructional preferences and how the learners
felt they learned mathematical content best. Statistically, many students do not see the relevance
of Algebra and have encountered negative experience with mathematics. This can be a pre-
cursor for math anxiety, which is “an emotional reaction to mathematics based on a past
unpleasant experience which harms future learning” (Professor Freeman – Western Wyoming
Community College). Studies show that one-half of all students in a developmental mathematics
class suffer forms of this type of anxiety. Two eighth-grade math classes completed the survey
using Google Forms: http://2short.net/rP. See Appendix B.
The results of the survey are as followed. Approximately thirteen percent of the survey
takers had parents that achieved a college degree or higher. The average household size was four
people. According to Professor Freeman’s guide to the math anxiety survey, approximately 47%
of the students surveyed have math anxiety.

3C ARCS TABLE
Project Goal Statement: The students will find the correct solution to a minimum of 7 out of 10
problems involving solving systems of equations using the elimination method.
ATTENTION
A.1 Perceptual Arousal
The teacher will attempt to make a call from his/her mobile phone, but will learn from the
operator that his/her phone has been disconnected.
The teacher will explain to the learners that (s)he had been warned by his/her parents not to go
over their service limits or the service would terminated, and the teacher would have to get
his/her own service.
The teacher states how choosing the correct cell phone service provider is a dilemma because
there are so many plans and options to choose from and (s)he doesn’t know how to choose the
best plan for his/her communication habits.
The teacher then tells the learners that after this lesson, they will know how to compare mobile
service plans and ultimately determine the best provider and/or plan for themselves.
A.2 Inquiry Arousal
The teacher will ask learners how they suppose cell phone plans can be compared using math and
content that they previously learned in the unit.
A.3 Variability The teacher will repeatedly explain how (s)he desperately needs the learners’ help in making the
right decision for a cell phone plan.
The teacher will keep students engaged by randomly checking for understanding, random
questioning.

PART 4 INSTRUCTOR GUIDE
INTRODUCTION
ACTIVATE ATTENTION
1. Gain the learners’ attention, by first going over the answers to the warm-up. The warm-
up will address skills students must possess prior to instruction. A screenshot of the
warm-up can be found in Appendix C.
2. Announce the title of the lesson and the objectives.
ESTABLISH PURPOSE
1. Announce to the class how they have previously learned that solving equations can help
solve problems in the real world.
2. Further explain how solving more than one equation simultaneously (systems) allows us
to solve even more real world problems.
3. State upon the completion of the lesson, the students will be able to solve a real dilemma
for teenagers by solving systems of equations.
AROUSE INTEREST AND MOTIVATION
Break from the instruction with a dramatic pause and proceed with the motivational script
included in Appendix D.
PREVIEW LEARNING ACTIVITY
As this instruction is highly supplantive, the lesson overview will briefly outline the events in the
instruction. For example, an instructor might say the following:
In this lesson, we will solve systems of equations using the
elimination method, which involves addition, subtraction, and
multiplication. Finally, you will be able to predict the outcome when
solving a systems of equations that consist of parallel and coincident
lines. You will practice every step in the process. At the conclusion
of the lesson, you will compare actual mobile service plans using the
elimination method to solve systems of equations. In a few days you
will have a quiz on this lesson and on the chapter test, you’ll be
tested on your ability to accurately solve systems of equations and
apply your knowledge in real-world situations.
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT
Copyright © 2010, Vertoria D. Lagroon 16
BODY
ACTIVATE PRIOR KNOWLEDGE
Explain to the learners that the elimination method is very similar to the substitution
method that they previously learned in that they have the same goal of getting one
equation that has only one variable. However, in the elimination method the goal will be
achieved by using the skills of adding and subtracting equations.
PRESENT INFORMATION AND EXAMPLES
The content will be presented in an expository sequence, in four components. You will facilitate
a Microsoft PowerPoint presentation using a Smart Board that breaks down instruction into four
segments. See Appendix F. Those segments are: addition, subtraction, multiplication, and
predicting outcomes. Each segment will include a detailed example for you to walk learners
through, followed by an example in which you will merely guide learners through. Segments
will conclude with two examples to be done solely by the learners for the purpose of checking
for understanding. You may choose to begin the first three segments with included video
examples. Between the segments, learners will practice the skills as explained in Guided
Practice.
FOCUS ATTENTION
Learners’ attention will remain focused by constant questioning and note-taking on a provided
graphic organizer. See Appendix E. During the guided examples, ask learners to tell and explain
every step in solving the system. This can be done quickly and efficiently through the use of
index cards or popsicle sticks with students names on them.
1. Get a stack of index cards or popsicle sticks.
2. Write the learners names on the cards or sticks. (One name per card)
It may be necessary to put some students in the stack more than once. This would be a
good idea for learners with shorter attention spans.
3. Simply pull a card or stick and address questions to learners whose name is drawn. The
randomness keeps learners alert. Also, learners will remain focused in order to
successfully complete the graphic organizer. Completion of the graphic organizer could
count for a portion of the daily participation grade.
EMPLOY LEARNING STRATEGIES
As the learning goal is procedural, learners will benefit from a mnemonic device to aid them in
memorizing the main steps in the procedure. There are four main steps to solving a system of
equations using elimination. The acronym LESS will be used as a mnemonic device to help
learners recall the critical steps. Provide learners with a connection between the word “Less”
and the elimination process. “We can remember LESS with the elimination method, because
sometimes it can be less work for us!”
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT
Copyright © 2010, Vertoria D. Lagroon 17
L Like terms aligned (write the system so that like terms are aligned)
E Eliminate one of the variables
S Solve the resulting equation for the remaining variable
S Substitute the value of the variable into one of the original equations and
solve for the other variable.
Give learners the note-taking graphic organizer. See Appendix E. The graphic organizer
will first, stress the mnemonic device mentioned above; then, separate information
concerning eliminating variables using three methods: addition, subtraction, and
multiplication. The worksheet will also include a table to compare and contrast properties
of parallel and coincident lines as related to solving a system of equations.
GUIDED PRACTICE
Practice will occur throughout the instruction at the end of the four major segments. Learners
will have the opportunity to practice the elimination method using addition, subtraction, and
multiplication. Learners will also practice predicting the outcomes of the elimination method:
parallel and coincident lines.
1. At the conclusion of each segment, give learners the respective practice sheets.
See Appendix G for the four practice sheets and answer keys.
2. Allow students to work in appropriate pairs.
3. It is suggested that learners complete at least five practice problems for each segment.
Assign the first five problems and allow early finishers to complete the remaining
problems, while other learners finish.
4. Refer students to their notes during practice and continue to emphasize LESS.
FEEDBACK
1. Provide motivational and informational feedback. Give positive reinforcement and
constructive information.
2. Provide feedback on every step of the LESS procedure. During practice, give learners
information so they can determine if they are right or wrong and why they are right or
wrong before giving them the correct answer.
3. Give learners information on their progress. Explain patterns of errors to learners and
inform them of how close they are to mastering the entire procedure.
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT
Copyright © 2010, Vertoria D. Lagroon 18
CONCLUSION
SUMMARIZE AND REVIEW
1. Review the LESS procedure and briefly summarize the variations in the procedure when
learners have to add, subtract, and multiply.
2. Conclude instruction by presenting the sequence of steps a final time for a simple case
and then build up to a complex case.
3. Stress again common problem areas for learners to be cautious of like distributing the
negative during subtraction.
TRANSFER LEARNING
Allow learners to apply their new knowledge and skills to a real-life situation through comparing
mobile service plans.
1. Provide learners with a listing of current rates for mobile service plans. See Appendix H.
2. Have learners construct systems of equations that align with the given information.
3. Then, have learners solve the systems using the elimination method.
4. Have learners determine the best mobile service plan for you and for themselves.
Learning can also be transferred through similar examples comparing car rental rates and the
optional use of the application instructional video that is included.
CLOSURE
Announce the conclusion of the lesson and thank the learners for their active participation and
attentiveness. Also, thank the learners for helping you choose the most cost efficient mobile
service plan that matches your communication needs. Express to the learners how confident you
are in them that they are now able to be savvy shoppers using Algebra.
ASSESSMENT
Learning will be assessed to determine whether learners have achieved the goal of the
instruction. Learners will be assessed on their ability to apply the procedure when solving a
system of equations. Students will complete a quiz on solving systems of equations using the
elimination method. See Appendix I for assessment quiz and KEY.
FEEDBACK
1. Grade the assessment quiz according to the key and rubric.
2. Return graded quizzes to learners and provide feedback on the percentage correct and
number of objectives successfully mastered.
3. Determine weaknesses and provide remedial instruction in those areas where needed.

PART 6 FORMATIVE EVALUATION PLAN
6A EXPERT REVIEW
The Subject Matter Expert that evaluated the instructional design was Kelly Coxe, McCormick
County School District Director of Instruction for grades 6th
through 12th
, district technology
coordinator, and former mathematics teacher. Mrs. Coxe proved be perfect for this position, as
she has experience teaching mathematics and overseeing new instruction and technology that is
brought to the district. The evaluation survey, created in Google Documents, and the
instructional materials were made available to Mrs. Coxe in June 2010. Mrs. Coxe completed
the survey and provided feedback in July 2010.
Link to the survey: http://bit.ly/bUykwB
6B ONE-TO-ONE EVALUATION
A small group of three eighth grade students will complete the instructional packet under
conditions similar to the finalized instruction to be implemented. An instructor will facilitate
while the learners progress through the instruction entirely. The students would be asked to
provide comments and suggestions on the delivery of instruction, worksheets, length of time to
complete instruction, and assessment of learning. Learners would individually be asked if there
were any unclear or confusing parts in the instruction. Did the design of the instruction keep
your focus and attention? Were you motivated to achieve the learning goal? Did you see the
importance of learning how to solve systems of equations using elimination? Would you be able
to apply the learning goal to other real-world situations on your own? Did the assessment quiz
align with the instruction? Were you prepared for the assessment quiz upon the completion on
the instruction? Is there anything you would change or add to the learning materials? All
responses would be recorded on the draft materials. Results would be analyzed and learning
materials would be modified appropriately.
6C SMALL GROUP EVALUATION
A small group of 15 students will proceed through portions of the instruction and provide
feedback. The group of students will be comprised of learners that took Algebra 1 the past
school year. There were five Algebra 1 classes during the last school year. The previous teachers
submitted the names of the learners with the highest average, a median average, and the lowest
average from each class last year. The instruction consists of five major components. Those
components are the four instructional segments that break down the procedure of solving
systems of equations and the transfer learning section. Each component of the instruction that
was revised according to the one-to-one evaluation was evaluated by three students: highest,
average, and lowest average learners from a class last year. The instructor would follow the
procedure outlined in the Instructor Guide and use the learning materials to provide instruction to
the sample of learners on solving systems of equations using elimination. The instructional
designer would observe the instruction and record notes on teacher/student interaction, use of
EDTECH 503 FINAL INSTRUCTIONAL DESIGN PROJECT

time, student motivation, and mastery of the learning goal from practice worksheets. Finally, the
instructor and learners would be asked how they feel about the delivery of the instruction and for
suggestion on improving the instruction. Delivery of instruction and learning materials would be
modified according to the results of the material evaluations.
6D FIELD TRIAL
Two Algebra 1 classes will field the instruction. During this field trial approximately twenty-
four to fifty-six students will receive the revised instruction. The instructor will follow the
modified Instructor Guide and guide learners through the instruction entirely. The instructional
designer will observe the instruction and record notes. Evaluation data will be analyzed along
with results of the assessment quizzes. The instructor and a sample of the students that
participated in the field trial will be interviewed. Questions will be similar to questions from the
one-to-one and group evaluation.

7B EXPERT REVIEW REPORT
The overall results of the survey were positive. The Subject Matter Expert (SME) responded
favorably to all questions. The SME felt that the learning materials and instructions were
appropriate and accurate. The SME responded that the learning materials were arranged in a
logical sequence and would support learner success. The SME also responded highly of the
instructor guide: answering that it was easy to follow and would lead students to achievement of
the learning goal. The SME responded that the most valuable learning materials were the
PowerPoint Notes and Packet and the motivational script. She described how the PowerPoint
Notes were easy to follow from an instructor and student viewpoint. She detailed how the notes
broke the content down into meaningful chunks. The SME responded that the PowerPoint notes
could possibly be used in alternative settings where the facilitator may not be a certified
mathematics teacher. She stated that the motivational script would gain student interest and focus
their attention. The SME responded that instructions concerning the amount of time various
activities should take should be included in the instructor guide, as well as the overall amount
time needed to complete the entire instruction. The SME raised concerns about the amount of
content covered in the instructional design versus the amount of class time, which is fifty
minutes.
7C COMMENTS ON CHANGE
After meeting with the Subject Matter Expert (SME) and analyzing the expert review survey
results, the following changes will be made to improve the instruction. The SME felt that time
guides should be included in the instructor guide to inform the instructor on the amount of time
each activity should take to complete. I will also add a statement that informs the instructor that
the instruction should take 2 class periods to complete, as the district runs on the traditional fifty
minute class schedules. The SME suggested that notes on accommodations be included to aid
instructors in accommodating learners with special needs. The SME suggested explicitly stating
in the instructor guide that assigning less problems for learners with special needs would help
with the time component. Those changes will be made. The SME also felt that the assessment
quiz was a good tool for measuring student success of the learning goal. However, she felt that a
rubric would be better than a key for grading the quiz. The SME determined that learners should
be assessed on every step of the procedure and not just the end result. A rubric will be developed
and added to the instructional design packet so that every step of the procedure can be assessed.
All changes will be made at a later time.

APPENDIX D: MOTIVATIONAL SCRIPT
Note: Script does not have to be followed exactly. A cell phone prop is needed. This can be an
actual cell phone or a toy.
Teacher
Says:
Excuse me, class. I need to make a very important phone call before we begin
the lesson.
Teacher takes out his or her cell phone and makes several attempts to make a phone call.
Teacher appears to get frustrated that phone is not working. Teacher then gives a facial
expression that gives students the notion that (s)he has finally discovered the solution to the cell
phone problem.
Teacher
Says:
(Sadly) Oh no! I just remembered that I didn’t pay my phone bill and my
service has been disconnected. I have been having an issue of going over my
monthly minutes and text messages allowance. I ran my bill through the roof
and can’t afford to pay it off right now.
Teacher perks up as if (s)he has just had an epiphany – gets a bright idea.
Teacher
Says:
(happily) After I pay this bill off, I am going to switch plans or service
providers. I need to find a plan that fits my communication needs, but also
inexpensive.
Teacher
Says:
But how will I ever determine which plan is right for my communication habits
and budget, with so many plans out there to choose from?
The teacher seems to ponder the answer to the question. At the point, the teacher may even take
suggestions from students.
Teacher
Says:
In today’s lesson we will learn how to use systems of equations to compare
mobile service plans and decide which plan is the best deal available. I really
need your help on this!

Slide 4
Announce to the class how they have previously learned that solving equations can help solve problems in the real world. Further explain how solving more than one equation simultaneously (systems) allows us to solve even more real world problems. State upon the completion of the lesson, the students will be able to solve a real dilemma for teenagers by solving systems of equations. Break from the instruction with a dramatic pause and proceed with the motivational script included in Appendix D
Slide 5
Hand out the graphic organizer that is to be completed by the learners during instruction. Learners’ attention will remain focused by constant questioning and note-taking on the provided graphic organizer. See Appendix E SAY: In this lesson, we will solve systems of equations using the elimination method, which involves addition, subtraction, and multiplication. Finally, you will be able to predict the outcome when solving a systems of equations that consist of parallel and coincident lines. You will practice every step in the process. At the conclusion of the lesson, you will compare actual mobile service plans using the elimination method to solve systems of equations. In a few days you will have a quiz on this lesson and on the chapter test, you’ll be tested on your ability to accurately solve systems of equations and apply your knowledge in real-world situations.

Slide 6
SAY: Another method for solving
systems of equations is
elimination. Like substitution, the goal of elimination is to get
one equation that has only one variable. To do this by
elimination, you add the two equations in the system
together. Remember that an equation
stays balanced if you add equal amounts to both sides. So, if 5x
+ 2y = 1, you can add 5x + 2y to one side of an equation and
1 to the other side and the
balance is maintained.
Since –2y and 2y have opposite
coefficients, the y-term is eliminated. The result is one
equation that has only one variable: 6x = –18.
When you use the elimination method to solve a system of
linear equations, align all like terms in the equations. Then
determine whether any like
terms can be eliminated because they have opposite

coefficients.
Slide 7
Solving Systems of Equations by Elimination
LESS
L Like terms aligned (write the system so that like terms are aligned)
EEliminate one of the variables
S
Solve the resulting equation for the remaining variable
SSubstitute the value of the variable into one of the original equations and solve for the other variable
SAY: There are four main steps to solving a system of equations using elimination. The acronym LESS will be used as a mnemonic device to help you recall the critical steps. “We can remember LESS with the elimination method, because sometimes it can be less work for us!” READ SLIDE

APPLICATION WORKSHEET
Instructions: Use the information on the previous sheet to write equations according to the
directions below. Create systems of equations that align with the rate plans and solve them
using the elimination method. Record answers in the provided table.
Example: Compare AT&T 450 and AT&T 900
AT&T 450 → y = 39.99 + .45x → .45x – y = -39.99
(400, 219.99)
AT&T 900 → y = 59.99 + .40x → .40x – y = -59.99
You can conclude that the prices of these plans would be the same if the customer uses 400
minutes over the allowance. That price would be $219.99

Justify your answer. Which plan would be best for you? Justify your answer.
The teacher talks 1050 minutes, which is 150 minutes over the 900-minute limit. Since
150 is over the 25-minute mark, an unlimited plan would be best for the teacher.
Because the teacher uses text and data services, the Sprint Unlimited plan is the best
deal. (Answers will vary)
