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
How many questions are on the 3rd grade MCAS Math test?
The full grade 3 MCAS Math has about 36-42 questions across two sessions. Item types are multiple choice, short-answer (type a number), and one or two longer constructed-response items where your child shows work and explains thinking.
Is a calculator allowed on the 3rd grade MCAS?
No. Massachusetts doesn’t allow calculators on the grade 3 math test. Multiplication facts through \(10\times 10\) need to be automatic, and your child should handle multi-digit addition, subtraction, and basic division on paper.
How long does the MCAS Math take?
Each of the two sessions runs about 65-85 minutes. Most third-graders finish in 60-75 per session. The sessions are typically given on consecutive school days, so total math testing is around 2-2.5 hours.
What’s a passing score on the 3rd grade MCAS?
MCAS uses four levels: Not Meeting Expectations, Partially Meeting Expectations, Meeting Expectations, and Exceeding Expectations. Meeting Expectations is on-grade-level. There’s no automatic retention rule tied to MCAS at grade 3 – that’s a district call.
Can my child retake the MCAS Math?
No. The grade 3 MCAS is given once per year, in the spring. The spring score is the official record. Schools may give other diagnostic tests through the year, but those don’t replace MCAS.
What math topics are on the 3rd grade MCAS?
Multiplication and division within 100, fractions on a number line, equivalent fractions, area and perimeter of rectangles, place value to 1,000, multi-digit addition and subtraction, time to the minute, measurement, and reading bar and picture graphs.
How long should we study for the MCAS Math?
For an on-grade-level child, 4-6 weeks at 15-20 minutes daily is plenty. For a child who’s struggling, 8-12 weeks at 25 minutes daily works better. Multiplication facts come first – they’re the single most useful skill at grade 3.
Where can we find more 3rd grade MCAS practice?
EffortlessMath has the Top 10 MCAS Math Practice Questions, a longer MCAS Math practice test, additional question sets, and the Mastering Grade 3 Math workbook with worked examples across every Massachusetts standard.
Does the MCAS align with Common Core?
Yes. Massachusetts’s Curriculum Framework for Mathematics is Common Core-aligned for grade 3 with minor state-specific clarifications. Multiplication, fractions, area, and place value match CCSS one-to-one.
How can I help my child prep at home?
Three habits stand out: (1) 5 minutes of multiplication-fact drill daily, (2) one word problem at dinner where your child explains the steps, and (3) one short timed practice set on the weekend. Practice having your child write a sentence with each answer – MCAS scorers reward clear explanations on the constructed-response items.
