Answers:

2- D
\(14 × 40 = 560\)

3- C
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 35 and 45, so the answer is 40

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

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

Massachusetts DESE shares released MCAS questions and practice materials online, and many released item sets can be viewed or printed. Keep in mind the real grade 3 test is taken on a computer, so mix printed practice with some on-screen work. This sample set is a good first step before a longer practice test, since it shows which topics need attention.

What is on the MCAS grade 3 math test?

Grade 3 MCAS math follows the Massachusetts Curriculum Framework and focuses on multiplication and division within 100, fractions on a number line, area and perimeter, place value to 1,000, telling time and solving two-step word problems. Expect multiple choice, short typed answers and at least one constructed-response question where your child explains the steps. Calculators are not used at grade 3.

Is there an MCAS grade 3 math reference sheet?

Check the DESE MCAS resources page for the reference materials that go with each grade’s math test, since they can change from year to year. At grade 3 most problems rely on facts your child should simply know, such as 60 minutes in an hour and the multiplication table through 10 × 10, so practice those rather than counting on a sheet.

What subjects are on the MCAS test in grade 3?

Massachusetts third graders take MCAS in English language arts and mathematics, usually in separate sessions during the spring testing window. Grade 3 is the first year of MCAS, so the computer format may be new. A few short practice sessions on a laptop or Chromebook, including typing a number answer and dragging items into place, help your child feel comfortable on test day.

How do I help my child with the MCAS grade 3 math practice test?

Sit with your child for the first try, read each word problem aloud together, and let them solve it on scrap paper. Afterward, go over every miss and ask how they got their answer. If an error repeats, such as mixing up the area and perimeter of a 4 by 6 rectangle (24 square units versus 20 units), spend a few days on that skill.
