2- D
\(14 × 40 = 560\)

3- D
24,589 is the sum of \(20,000; 4,000; 500; 80;\) and 9

4- C
\(A = 44 – (21 + 9)\)
\(A = 14\)

5- C
In 1 day 4 meals so \(4 × 7 = 28\) meals a week.

6- D
\(A = 72 ÷ 8\)
\(A= 9 \)

7- D
the model for the first fraction is divided into 6 equal parts. We shade 3_6 to show the same amount as 1_2. The model for the second fraction is divided into 8 equal parts. We shade 3_ 8 that it shows these two models are different fractions.

8- C
The arrow shows exactly the middle of two numbers 25 and 35, so the answer is 30.

9- 12
\(108 ÷ 9 = 12\)

10- C
the model for the first fraction is divided into 8 equal parts. We shade 2_ 8 to show the same amount as 1_ 4. The model for the second fraction is divided into 16 equal parts. We shade 4_ 16 to show the same amount as 1_ 4.

Frequently Asked Questions

What is on the 3rd grade MCAS math test?

The grade 3 MCAS Math test follows the Massachusetts Curriculum Framework, which is closely based on the Common Core. Main topics are multiplication and division within 100, fractions on a number line and equivalent fractions, area and perimeter of rectangles, place value and rounding to 1,000, telling time and measurement. Fact fluency matters, since calculators are not allowed at grade 3.

Is there an MCAS 3rd grade math practice test PDF?

Yes. The Massachusetts Department of Elementary and Secondary Education (DESE) posts released MCAS test items and practice tests for grade 3 math, and many can be printed. The computer-based practice test is also worth trying, because most students take MCAS online. Let your child work through it in one sitting, then talk through any question where the reasoning went off track.

What kinds of questions are on the 3rd grade math MCAS?

Grade 3 MCAS Math uses multiple-choice items, short-answer items where your child enters a number, and constructed-response questions that ask for work and an explanation. A constructed-response question might ask how many stickers each of 9 friends gets from 108 stickers and why. Writing the equation, 108 ÷ 9 = 12, and one sentence of explanation earns more points than the answer alone.

Is there an MCAS 3rd grade math reference sheet?

Massachusetts provides mathematics reference sheets for some MCAS grades, so check the current DESE test materials to see what is offered for grade 3. Either way, third graders should know the basics without looking: 60 minutes in an hour, area of a rectangle equals length × width, and perimeter is the sum of all side lengths. Quick daily review makes these automatic.

Are there 3rd grade math MCAS practice worksheets?

Yes. Worksheets that focus on one skill at a time are a good way to prepare, for example a page on comparing fractions like 2/8 and 4/16 on a model, or a page of two-step word problems. Mix in a few written-explanation problems each week, since MCAS rewards clear reasoning. Short, frequent sessions of 15 to 20 minutes work well for third graders.
