mCLASS:MATH RESEARCH BASE

Screening and Progress Monitoring Guide Grade 2

Amplify Insight and research partners at Teachers College of Columbia University, developers of the

mCLASS:Math assessment, are building on a commitment to create educational products that not

only assess mathematical abilities but also provide a basis for differentiated instruction. The updates to

mCLASS:Math this year, based on rigorous research and analysis, introduce revisions to the assessment

forms and the calculations that determine Risk Levels, which are in turn used to determine Overall Status.

mCLASS:Math is based on modern developmental, educational, and cognitive research that shows how

students acquire mathematical knowledge. The research underlying the assessment highlights several

essential facets of a student’s mathematical learning:

• Students develop everyday mathematical knowledge outside school and use it to assimilate what

is taught in school.

• Basic skills and conceptual understanding are both essential for mathematics proficiency.

• Students use a variety of strategies to solve mathematical problems.

• Limitations in memory contribute to a student’s mathematics difficulties.

• Students with mathematical learning difficulties often possess important intellectual strengths, such

as informal strategies useful for counting.

mCLASS:Math provides assessors a way to use these research findings and ideas in their pedagogy with

tools that interpret a student’s answers and behavior and then suggest an effective approach to instruction.

Assessors must be able to track not only what their students understand, but also how they understand.

Administrators should be guided by a research- and theory-based view of mathematical proficiency.

Evaluations ought to measure how effectively programs promote both basic skills and deeper

understanding. The development of mCLASS:Math brings the research findings and theories to bear on

the thinking and practice of both assessors and administrators.

mCLASS:Math draws on three major schools of thought.

1. The extensive cognitive science literature of “Mathematical Thinking and Learning” (Ginsburg,

Cannon, Eisenband, & Pappas, 2006), “The Development of Children’s Mathematical Thinking”

(Ginsburg, Klein, & Starkey, 1998), and other supporting publications shaped the development of

mCLASS:Math so it would:

• Embed key cognitive concepts

• Include a focus on Number Sense, shown to be important in predicting academic achievement

• Consider the memory limitations that appear to contribute to mathematics

learning problems

• Account for strategies and backup strategies that underlie a student’s arithmetic, as well as

the concepts that demonstrate understanding of the basic operations

2

mCLASS:MATH RESEARCH BASE

Screening and Progress Monitoring Guide Grade 2

2. Curriculum-Based Measurement (CBM), the two-part screening and progress monitoring

methodology, promotes repeated assessment to advance long-range instructional goals. Teachers

with mCLASS:Math use CBM methodology when they:

• Administer short assessments on a frequent basis

• Graph scores to evaluate a student’s progress toward specific goals

• Use data to determine the effectiveness of instruction and identify students who might be

struggling or who are at risk

• Monitor progress by administering alternate measure forms to evaluate whether students

are on track or require intervention to meet identified goals

3. The tradition of clinical interviewing, originally developed by Jean Piaget and used extensively since

that time in cognitive developmental research and education, defines the kind of flexible questioning

that is especially valuable for formative assessment in the classroom. mCLASS:Math Diagnostic

Interviews use this approach to:

• Help educators uncover underlying thinking in a way that standard tests or CBM

measures cannot

• Guide the teacher through complex questioning and prompt them to examine and record

the different strategies students use to solve problems

Categories of Mathematical ThinkingThe mCLASS:Math Screening and Progress Monitoring assessments combine three categories of

mathematical thinking (quick retrieval, number sense, and written computation) to cover the essential

skills of early mathematics.

Quick RetrievalQuick retrieval of the basic number facts, or combinations, is both important for learning mathematics and

useful for a CBM task. Research shows that knowledge of number combinations predicts achievement

and that students who experience difficulty with math often do poorly on number combinations. In its

essence, quick retrieval means that students get the answer quickly and do not have to expend much

mental energy on calculation. Quick retrieval may result from rote memory or from fluency using rapid

counting or basic principles such as the commutativity of addition. mCLASS:Math assesses quick retrieval

through the Number Facts measure.

mCLASS:MATH RESEARCH BASE

Screening and Progress Monitoring Guide Grade 2

Number SenseA series of items gauge a student’s general ability to draw conclusions from working with numbers.

Number sense involves basic intuitions and ideas about numbers, including concepts that make

computation easier or eliminate the need for it altogether. Number sense includes the ability to compare

the magnitude of numbers, to understand the relative effect of arithmetical operations on numbers,

and to have meaningful referents for number and quantity. It also includes the ability to know whether

certain numbers are plausible answers to certain problems, to break numbers into convenient parts that

make calculation easier, and to apply basic operational rules to arithmetic equations. mCLASS:Math uses

multiple indicators to evaluate number sense.

In second and third grade, mCLASS:Math measures a student’s ability to discern the difference in a pair

of numbers or simple equations (Quantity Discrimination), and to provide a fourth number when three

numbers are given in an identifiable sequence (Missing Number).

Written ComputationThis straightforward category involves basic reading and understanding of written mathematics. Previous

research has found high alternate form reliability, test-retest reliability, and criterion validity for this kind

of measure.

In second and third grade, the Computation measure examines basic reading and calculation ability,

and knowledge of arithmetical rules and concepts. It also tests conceptual understanding using complex

written addition, subtraction, and multiplication problems, which are designed to elicit and identify

common and systematic errors that students make as they master the algorithms for written calculation.

Research FindingsAmplify Insight and Teachers College of Columbia University, together with the University of Missouri,

received a Goal 5 grant from the Institute of Education Sciences (IES) at the U.S. Department

of Education for the purpose of developing, revising, and evaluating mCLASS:Math. Since 2007, the

Amplify research team and teachers across the country have been administering mCLASS:Math’s grade-

appropriate measures to thousands of students from kindergarten through Grade 3. The team found

strong correlations between the mCLASS:Math measures and criterion variables, which were each

student’s proficiency level on a state standardized achievement test and/or performance distributions

from the national sample, demonstrating that the measures are valid indicators of early mathematics

performance.

mCLASS:MATH RESEARCH BASE

Screening and Progress Monitoring Guide Grade 2

Overall recommendations were established by examining benchmark classifications in relation to a

criterion variable, the Woodcock-Johnson III Broad Math achievement measure, as well as performance

distributions from the national sample. By comparing results from the standardized assessment to

mCLASS:Math data collected at the beginning, middle, and end of the 2008-2011 school years, the

researchers were able to determine benchmarks for each measure.

Using this research data, students were considered at risk for difficulty achieving a goal if they performed

in the lowest 33rd percentile of sample norms on the standardized assessment at the end of the academic

year. Alternately, students who performed at or above the 67th percentile on the standardized assessment

were considered to be at low risk. Benchmark classifications for the mCLASS:Math measures at the

beginning, middle, and end of the school year were then determined by calculating the score points that

most accurately placed students in the low-risk or high-risk categories based on their Woodcock-Johnson

III Broad Math scores.

RISK LEVELS AND OVERALL STATUS

Screening and Progress Monitoring Guide Grade 2

Risk Levels and Benchmark GoalsAs an index of performance on an individual measure, Risk Levels of Deficit, Emerging, or Established are

assigned relative to that measure’s goal, the student’s grade, and the time of year. On both the mobile

device and the web, each Risk Level is represented by a colored box.

Each assessment period has its own Benchmark Goal, which is the fluency score required to be Established

at that time of year. As an example, during the middle of the year, Grade 2 students who are identifying

5-9 missing numbers in two minutes are not hitting the Benchmark Goal and are considered Emerging.

Students who score 4 or less are considered Deficit. Those who score 10 or more meet the Benchmark

Goal and are considered Established.

Keep in mind, Benchmark Goals are minimums. Ultimately, all students should be Established by or

during the End-of-Year assessment period; this is called the End-of-Year Goal. For instance, every second

grader should be able to solve 24 computation problems before the year’s end.

ComputationComputation evaluates a student’s ability to solve complex written calculation problems. To be successful

on these types of problems, students must identify the operation, determine whether regrouping is

necessary, and correctly execute the appropriate algorithm for the operation. To accomplish this goal,

students rely on their understanding of the place-value structure of the base-ten number system and

numerical patterns. Adding (or deducting) the carried/borrowed number(s) in the correct place value

position is imperative for success.

The End-of-Year Goal for Computation is 24 or more for Grade 2.

Overall StatusAfter the student has completed all of the applicable measures for an assessment period, an Overall

Status is designated, signifying the amount of instructional support that may be necessary for a student

to continue on a path toward success in mathematics.

Rectangular icons represent the student’s Risk Level on an individual measure.

Deficit (red) – Far below benchmark expectations

Emerging (yellow) – Advancing toward, but not meeting, benchmark expectations

Established (green) – Meets or exceeds benchmark expectations

The circular Overall Status icon represents the general instructional support recommended for a

young student to become a well-developed, mature student of mathematics. Grade 2 Overall Status

recommendations are determined based on the Risk Levels from the Number Facts, Quantity Discrimination,

Computation, Concepts, and Missing Number measures.

COMPUTATION

Screening and Progress Monitoring Guide Grade 2

Computation is a two-minute measure used to evaluate a student’s ability to solve complex written

calculation problems. The assessment can be administered to individual students or a group of students

at one time. The teacher gives each student three pages of Computation worksheets containing 30

problems and times the students during the assessment. The teacher then scores the worksheets and

enters the students’ scores on mCLASS:Home. Performance is based on the total number of correct digits

in each problem.

PurposeStudents need to know how to solve complex operational problems. To answer these items successfully,

students must identify the operation, determine whether regrouping is necessary, and correctly execute

the algorithm appropriate for the operation. To accomplish this goal, students rely on their understanding

of the place-value structure of the base-ten number system and numerical patterns. Adding (or

deducting) the carried/borrowed number(s) in the correct place-value position is imperative for success.

Similarly, retrieval of simple number facts frees students to focus on the more complex procedural and

conceptual aspects of the problem. Some students may quickly and easily retrieve number facts, identify

numerical patterns, and grasp the base-ten system, but still have difficulty reconciling this knowledge

with place value concepts.

MaterialsComputation worksheets from the Grade 2 Screening and Progress Monitoring Student Materials,

which can be downloaded from the Support & Resource Center on mCLASS:Home.

AdministrationAfter distributing the Computation worksheets to the students, say, “Please write your name and date

at the top of the first worksheet, put your pencil down, and turn the worksheets over.” Wait until each

student completes this task.

Next, say, “On these worksheets are some math problems. They look like this (hold example up/write

example on board (21 + 3)). These problems go from top to bottom. What is 21 + 3? (Give students

a chance to answer – possible explanation: 1 + 3 is 4, and bring down the 2, so the answer is 24.)

Remember to pay attention to the sign; you may see other types of problems such as subtraction. You

will have two minutes to answer as many math problems as you can. There will be more problems than

you can answer. You are NOT expected to finish all the problems, just answer as many as you can. Some

of the problems will be easy while others will be hard. If you come to one that is hard or that you do not

know how to do, SKIP IT and come back to it later. Please write your answers neatly and show all your

work on the worksheet. When I say BEGIN, turn your worksheets over, write your answer to the FIRST

problem, and work DOWN the page. Then go to the next column. When you finish a page, continue to

the next one. Keep working until I say STOP. Are there any questions?”

Answer all questions before beginning the assessment. Next, say, “BEGIN.”

Screening and Progress Monitoring Guide Grade 2

Give the students two minutes to complete the measure. When time is up, say, “STOP. Put your

pencils down.”

Collect the Computation worksheets, and use the corresponding answer key in this guide to score them.

Scoring RulesScoring: The student receives a score of one point for each correct digit in the answer. The number

of correct digits for each answer within the two-minute time frame is the student’s score and a more

sensitive measure of student change. Score problems in the direction in which they are typically

calculated. Specifically, score addition, subtraction, and multiplication problems from right to left and

division problems from left to right. For example, a student would receive a score of one point on the

following addition problem:

A score of one point on the following subtraction problem:

A score of two points on the following multiplication problem:

And a score of one point on the following division problem:

Student Stops: If a student stops working before the end of the two minutes, say, “Keep working until

I say STOP.” This should be an individual prompt given quietly to address a targeted need.

Excessive Skipping: If a student skips familiar or easy problems, say, “Try each problem before moving

on to the next. Do not skip problems you can do.” This should be an individual prompt given quietly to

address a targeted need.

CONCEPTS

113Screening and Progress Monitoring Guide Grade 2

CONCEPTS

Concepts is a two-minute measure that directly assesses a student’s knowledge of place-value concepts,

notational understanding, fractions, and addition, subtraction, multiplication, and division principles. The

teacher gives each student three pages of Concepts worksheets containing 24 problems and times the

students during the assessment. The teacher then scores the worksheets and enters the students’ scores

on mCLASS:Home. Performance is based on the total number of correct answers.

Purpose The Concepts measure evaluates a student’s ability to understand and use fundamental properties of

operations and concepts to solve problems. For example, if 58 x 9 = 522, the commutative principle can

be applied to 9 x 58, thereby rendering computations unnecessary. Successful execution of algorithms

also requires an understanding of place value concepts. The ability to identify the place value of a number

is essential for regrouping. Students must also learn to recognize, represent, and generate equivalent

forms of commonly used fractions (for example, word forms, models, etc.).

MaterialsConcepts worksheets from the Grade 2 Screening and Progress Monitoring Student Materials, which

can be downloaded from the Support & Resource Center on mCLASS:Home.

AdministrationAfter distributing the Concepts worksheets to the students, say, “Please write your name and date at

the top of the first worksheet, put your pencil down, and turn the worksheets over.” Wait until each

student completes this task.

Next, say, “On the other side of the sheet are some math problems. Some of them look like this.”

Hold up the example or put the example on a board by drawing a bar divided into four equal parts with

one part shaded. Under the bar, write the answers A) 14 B) 4

6 C) 35.

Continue by saying, “You have to circle the correct answer. What fraction shows the part that is shaded

in? (Give students a chance to answer – possible explanation –There are four boxes, and one box is

shaded in, so 1 out of 4 boxes is shaded. The answer is A) 14.) You will have two minutes to answer

as many math problems as you can. There will be more problems than you can answer. You are NOT

expected to finish all the problems, just answer as many as you can. Some of the problems will be easy

while others will be hard. If you come to one that is hard or that you do not know how to do, SKIP IT

and come back to it later. Please write your answers neatly and show all your work on the worksheet.

When I say BEGIN, turn your worksheets over, write your answer to the FIRST problem, and work DOWN

the page. Then go to the next column. When you finish a page, continue to the next one. Keep working

until I say STOP. Are there any questions?”

114 Screening and Progress Monitoring Guide Grade 2

CONCEPTS

Answer all questions before beginning the assessment. Next say, “BEGIN.”

Give the students two minutes to complete the measure. When time is up, say, “STOP. Put your

pencils down.”

Collect the Concepts worksheets, and use the corresponding answer key in this guide to score them.

Scoring RulesScoring: The student receives a score of one point for each correct answer. If an answer has multiple

parts, all of them need to be correct to score the point.

Student Stops: If a student stops working before the end of the two minutes, say, “Keep working until

I say STOP.” This should be an individual prompt given quietly to address a targeted need.

Excessive Skipping: If a student skips familiar or easy problems, say, “Try each problem before moving

on to the next. Do not skip problems you can do.” This should be an individual prompt given quietly to

address a targeted need.

Data Entry1. When you finish scoring the worksheets, log in to mCLASS:Home, go to mCLASS:Math, and open

MISSING NUMBER

211Screening and Progress Monitoring Guide Grade 2

MISSING NUMBER

Missing Number is a two-minute measure that evaluates a student’s recognition of complex numerical

patterns and familiarity with printed numbers. The teacher gives each student a Missing Number

worksheet containing 22 problems and times the students during the assessment. The teacher then

scores the worksheets and enters the students’ scores on mCLASS:Home. Performance is based on the

total number of correct answers.

Purpose Students need to recognize complex number patterns and be familiar with printed numbers to continue

developing number sense. To answer these items successfully, students must recognize the three printed

symbols as representations of numbers, identify what fourth number would complete the sequence,

and then name that number. Students who can quickly and accurately identify the missing number

recognize and make use of a fundamental pattern within the number sequence. Students who proceed

more slowly may have to go through a manual strategy to fill in the blank, perhaps counting from a

known reference up to the numbers in question (for example, counting from one to answer what is

missing in 9, 16, __, 30). Other students may not yet grasp the inherent relationship between numbers.

Materials Missing Number worksheet from the Grade 2 Screening and Progress Monitoring Student Materials,

which can be downloaded from the Support & Resource Center on mCLASS:Home.

AdministrationAfter distributing the Missing Number worksheets to the students, say, “Please write your name and

date at the top of the worksheet, put your pencil down, and turn the worksheet over.” Wait until each

student completes this task.

Next, say, “On the other side of the sheet are some math problems. They look like this (hold example

up/write example on board (2, 4, _, 8)). You have to complete the pattern in the problem. What number

goes in this blank? (Give students a chance to answer – possible explanation: We are counting by 2’s,

so 2, 4, 6, 8. 6 is the answer.) You will have two minutes to answer as many math problems as you can.

There will be more problems than you can answer. You are NOT expected to finish all the problems, just

answer as many as you can. Some of the problems will be easy while others will be hard. If you come

to one that is hard or that you do not know how to do, SKIP IT and come back to it later. Please write

your answers neatly on the worksheet. When I say BEGIN, turn your worksheet over, write your answer

to the FIRST problem, and work DOWN the page. Then go to the next column. Keep working until I say

STOP. Are there any questions?”

Answer all questions before beginning the assessment. Next, say, “BEGIN.”

212 Screening and Progress Monitoring Guide Grade 2

MISSING NUMBER

Give the students two minutes to complete the measure. When time is up, say, “STOP. Put your

pencils down.”

Collect the Missing Number worksheets, and use the corresponding answer key in this guide to

score them.

Scoring RulesScoring: The student receives a score of one point for each correct answer.

Student Stops: If a student stops working before the end of the two minutes, say, “Keep working until

I say STOP.” This should be an individual prompt given quietly to address a targeted need.

Excessive Skipping: If a student skips familiar or easy problems, say, “Try each problem before moving

on to the next. Do not skip problems you can do.” This should be an individual prompt given quietly to

address a targeted need.

Data Entry1. When you finish scoring the worksheets, log in to mCLASS:Home, go to mCLASS:Math, and open

the Class Report.

NUMBER FACTS

263Screening and Progress Monitoring Guide Grade 2

NUMBER FACTS

Number Facts is a two-minute measure that evaluates a student’s knowledge of basic arithmetic. The

teacher gives each student two pages of Number Facts worksheets containing 50 problems and times the

students during the assessment. The teacher then scores the worksheets and enters the students’ scores

on mCLASS:Home. Performance is based on the total number of correct answers.

Purpose Quick retrieval of the basic number facts, or combinations, is fundamentally important for learning and

predicts achievement. From a practical point of view, quick retrieval means that students get the answer

quickly and do not have to expend much mental energy on calculation. Quick retrieval may result from

rote memory or from fluency with rapid counting.

Materials Number Facts worksheets from the Grade 2 Screening and Progress Monitoring Student Materials,

which can be downloaded from the Support & Resource Center on mCLASS:Home.

AdministrationAfter distributing the Number Facts worksheets to the students, say, “Please write your name and date

at the top of the first worksheet, put your pencil down, and turn the worksheets over.” Wait until each

student completes this task.

Next, say, “On the other side of the sheet are some math problems. They look like this (hold example up/

write example on board (1 + 2)). These problems go across. What is 1 + 2? (Give students a chance to

answer – possible explanation – 1 + 2 is 3, so the answer is 3.) Remember to pay attention to the sign,

you may see other types of problems such as subtraction. You will have two minutes to answer as many

math problems as you can. There will be more problems than you can answer. You are NOT expected to

finish all the problems, just answer as many as you can. Some of the problems will be easy while others

will be hard. If you come to one that is hard or that you do not know how to do, SKIP IT and come

back to it later. Please write your answers neatly and show all your work on the worksheet. When I say

BEGIN, turn your worksheets over, write your answer to the FIRST problem, and work DOWN the page.

Then go to the next column. When you finish a page, continue to the next one. Keep working until I say

STOP. Are there any questions?”

Answer all questions before beginning the assessment. Next, say, “BEGIN.”

Give the students two minutes to complete the measure. When time is up, say, “STOP. Put your

pencils down.”

Collect the Number Facts worksheets, and use the corresponding answer key in this guide to

score them.

264 Screening and Progress Monitoring Guide Grade 2

NUMBER FACTS

Scoring RulesScoring: The student receives a score of one point for each correct answer.

Student Stops: If a student stops working before the end of the two minutes, say, “Keep working until

I say STOP.” This should be an individual prompt given quietly to address a targeted need.

Excessive Skipping: If a student skips familiar or easy problems, say, “Try each problem before moving

on to the next. Do not skip problems you can do.” This should be an individual prompt given quietly to

address a targeted need.

Data Entry1. When you finish scoring the worksheets, log in to mCLASS:Home, go to mCLASS:Math, and open

the Class Report.

QUANTITY DISCRIMINATION

315Screening and Progress Monitoring Guide Grade 2

QUANTITY DISCRIMINATION

Quantity Discrimination is a two-minute measure that identifies a student’s ability to comprehend the

quantitative value of whole numbers and operations using whole numbers, fractions, and decimals. The

teacher gives each student two pages of Quantity Discrimination worksheets containing 30 problems and

times the students during the assessment. The students should identify the number or quantity in the

set with the highest value. The teacher then scores the worksheets and enters the students’ scores on

mCLASS:Home. Performance is based on the total number of correct answers.

Purpose Comparing the magnitude of numbers is a fundamental number concept. Within a given item, a

student must recognize the written numerals and understand the value of one number is larger than

the other. The comparisons include fractions, decimals, and simple problems that could be solved

without calculation. Understanding quantity has been shown to be one of the strongest predictors of

mathematical performance.

Materials Quantity Discrimination worksheets from the Grade 2 Screening and Progress Monitoring Student Materials, which can be downloaded from the Support & Resource Center on mCLASS:Home.

Administration After distributing the Quantity Discrimination worksheets to the students, say, “Please write your name

and date at the top of the first worksheet, put your pencil down, and turn the worksheets over.” Wait

until each student completes this task.

Next, say, “On the other side of the sheet are sets of numbers. They look like this (hold example up/write

example on board (6 | 5 + 3)). You have to circle the side with the larger amount. Which side would

you circle? 6 or 5 + 3? (Give students a chance to answer – possible explanation: 5 + 3 = 8, and 8 is

larger than 6, so you would circle 5 + 3.) You will have two minutes to answer as many math problems

as you can. There will be more problems than you can answer. You are NOT expected to finish all the

problems, just answer as many as you can. Some of the problems will be easy while others will be hard.

If you come to one that is hard or that you do not know how to do, SKIP IT and come back to it later.

Please write your answers neatly and show all your work on the worksheet. When I say BEGIN, turn your

worksheets over and write your answers to the FIRST problem and work DOWN the page. Then go to

the next column. When you finish a page, continue to the next one. Keep working until I say STOP. Are

there any questions?”

Answer all questions before beginning the assessment. Next, say, “BEGIN.”

Give the students two minutes to complete the measure. When time is up, say, “STOP. Put your

pencils down.”

316 Screening and Progress Monitoring Guide Grade 2

QUANTITY DISCRIMINATION

Collect the Quantity Discrimination worksheets, and use the corresponding answer key in this guide to

score them.

Scoring Rules Scoring: The student receives a score of one point for each correct answer and loses a point for each

incorrect answer. Do not count skipped problems as incorrect answers. Subtract the number of incorrect

answers from the number of correct answers to calculate the total score.

Student Stops: If a student stops working before the end of the two minutes, say, “Keep working until

I say STOP.” This should be an individual prompt given quietly to address a targeted need.

Excessive Skipping: If a student skips familiar or easy problems, say, “Try each problem before moving

on to the next. Do not skip problems you can do.” This should be an individual prompt given quietly to

address a targeted need.

Data Entry1. When you finish scoring the worksheets, log in to mCLASS:Home, go to mCLASS:Math, and open

the Class Report.

2. To enter results for Benchmark assessments, make sure you are on the Screening tab; click the

Progress Monitoring tab to enter progress monitoring results.
