Massachusetts Comprehensive Assessment System (MCAS) Sample Questions: Grade 6 Math

The Massachusetts Comprehensive Assessment system, commonly abbreviated as MCAS is Massachusetts’s statewide standards-based assessment program. The students will face a variety of new technology-enhanced questions as a part of the Massachusetts Comprehensive Assessment System.

Some of them are Multiple choice-single correct responses, Multiple choice-multiple correct responses, Matching Tables, Drag and Drop, Hot text, Table Fill in, Graphing, Equation/numeric, Extended constructed response, Short answer, and many more.

Today, we will share several sample questions along with practice test links for Grade 6 Math that gives you an idea of questions that your students are likely to see on the test. After each sample question, an explanation follows that includes any important aspects of the task that you may need to consider with respect to the skills, processes, and information your students need to know.

MCAS Sample Questions: Grade 6 Math Sample Questions & Answers

Domain: Grade 6 >> Ratios & Proportional Relationships
Sample Question:

A school has an enrollment of 600 students. 330 of the students are girls. Express the fraction of students who are boys in lowest terms.
A. 12/20
B. 11/20
C. 9/20
D. 13/20
Answer: C
Answer Explanation:
First, to find the proper ratio, subtract the number of girls from the total number of students. The difference is the number of boys. 600-330 = 270. So, the initial ratio is 270/600.

Then, to reduce a ratio to its lowest term, divide the numerator and denominator by the Greatest Common Factor (GCF). Here, the GCF is 30. 270 divided by 30 = 9 and 600 divided by 30 = 20, so, the lowest ratio is 9/20.

Domain: Grade 6 >> The Number System
Sample Question:

Do the following operation:

A. 21/32
B. 1/2
C. 3/7
D. 6/7
Answer: D
Answer Explanation:
The original problem is:

3 /4 ÷ 7/8

To divide fractions, you must Keep (the first fraction), Change (the division to multiplication), Flip (the second fraction, or, take the reciprocal).

3 / 4 X 8 /7

= 24/28

Simplify by factoring out the GCF of 4.

The answer is 6/7

Sample Question:

Evaluate: 34
B. 12
C. 81
D. 1
Answer: C
Answer Explanation:
The base is 3

The exponent is 4

3 is multiplied 4 times, or 3 X 3 X 3 X 3 = 81
