– Some Reminders
– Back up your work!
– READ, READ, READ!!!
• Your Book
• Your Lab Manual
• The Course site
– WORK, WORK, WORK!!!
• It is your role to THINK, PLAN, PROCESS, DEVELOP, and DESIGN your projects.
– COMMUNICATE!!!
Scaffolding
What is it?
What does it look like in classrooms?

Spreadsheets
Moving from Productivity Tool to Thinking Tool
Buying a …
You have decided to buy a car. You must determine what will be a comfortable monthly payment for you. Design a spreadsheet that will help you outline your personal budget, then decide what car and payment you can afford.
1) What if the interest rate was 2.5%? 5.0%? 9.1%?
2) What if your monthly payment was $100? $250? $400?
Recognized as a Common ‘Mathematical’ Tool
Manipulating numbers is part of mathematics
But...storing and interpreting numerical data and asking questions about the data is essential to other content areas
“What total electoral vote would have resulted if a particular presidential candidate had received 5 percent more votes in a specific block of southern states?”
“How much would a 200-pound man weigh if he were transported to each of the other known planets?”
“Is it colder in November in Fargo, ND or in Juneau, AK?”
A spreadsheet is...
a tool that allows you to manipulate numbers (and words) and generate chart, graphs and reports.
a matrix of intersecting rows and columns.
a grid with columns designated by letters and rows designated by numbers on the left side.
- G & G p. 100-105
Basic SS Terminology
Columns (A, B,…) and Rows (1, 2,…)
Cell - intersection of column and row
Cells may contain -- Text and Values
– Letters
– Numbers
– Formulas - mathematical equations
– Functions - built in formulas (average, sum, ...)

What can we do with a SS?
Traditional purpose:preparing budgets and financial forecasting
Store and manipulate data for analysis; compare and contrast statistics
Perform calculations
Display data (charts and graphs)
Ask hypothetical questions -- What if?
Basic SS Functions
Storing (numerical) information
Calculating information
Presenting information
Critical thinking skills: collecting, organizing, describing, identifying relationships, hypothesizing, interpreting, analyzing data, etc.
(NOT limited to Math/older students)
Bloom’s Taxonomy - (M p. 18)
Application, Analysis, Synthesis, Evaluation
Classroom Applications
Administrative Uses (for Teachers)
– grade book, budget, statistics
Instructional Uses (for Students)
– teacher-created spreadsheet (provide initial scaffolding)
– student-created spreadsheet
Instructional Focus
– PBL
– What if? scenarios
Some Spreadsheet Ideas...
How much will it cost to keep a pet?
How much water and money is wasted by a dripping faucet?
Temperature comparisons
Compare various characteristics of cities (snowfall, crime rate, population) to assess quality of life
Counting, adding, comparing data -- M&M’s, coins, height, pets
Science: Plant growth, doubling rate, half-life, etc.
Some Spreadsheet Ideas...
Survey job opportunities to determine average salaries
Determine needs for a class fundraising event by analyzing possible costs and profits
Longitudinal analysis (voting, birth and death rates, war statistics) -- any interesting patterns or hypotheses?
Compare food prices, nutritional intake, effects of different types of exercise on heart rate
Problem: It is your job to take care of a house for one MONTH (30 days). Which payment method
would you prefer?
Calculate totals for the options below:
A) lump sum of $10,000
B) $25.25/hr for 5 hours per day
C) $0.01 -- doubles each day
D) $155 per day

Formulas vs. Functions
Formulas: Stated numerical relationships between the contents of different cells
=A1+B1+C1+D1+E1
Functions: Mathematical or logical operations that may be performed on the values in a set of specified cells (built in formulas)
=SUM (B1:B9)
=IF B9<B10, B9*E6
Values automatically adjusted
‘Fill’ command

How Old Are You?
Design a spreadsheet for the following…(Think about layout!)
Getting feedback on your age!
How old you are in years?
…months?
…weeks?
…days?
…hours?
…minutes?
…seconds?

Using - using and manipulating a completed spreadsheet; all data are in the file.

Hunter Taxonomy: Ways to use SS/DB with Students
Building - building a spreadsheet by entering the data into the cells; a template with labels and formulas is created, students need to find and enter data for cells.
