Answers:
1- B
An easy way to tell whether a large number is odd or even is to look at its final digit. If the number ends with an odd digit \((1, 3, 5, 7, or 9)\), then it’s odd. On the other hand, if the number ends with an even digit or \(0 (0, 2, 4, 6 or 8)\), then it is even.
15, 29, and 83 end with odd digits, so they are odd numbers.
2- D
She saved $36 and $28, so she has $64.
\($140 – $64 = $76\) she needs to save.
3- D
Michelle divides 72 books into 9 boxes; therefore, the formula \(72 ÷ 9\) is correct.
4- B
Eva gave 349 of her 983 cards to her friend, so her cards are \(983-349\), then she lost 260 cards so now she has \(983-349-260=374\) cards
5- D
Use our formula for a rectangle:
\(Area= length × width\)
Area \(=3cm×7cm =21cm^2\)
6- B
Add 4hundred and 8 tens and 4ones
So we have:\(400 + 80 + 4 = 484\)
7- A
The chances of landing on red are 3 in 6
The chances of landing on yellow are 1 in 6
The chances of landing on the green are 2 in 6
The chances of landing on red are more than other colors.
8- C
32 inches distance most often occurring in this table.
9- A
10- C
All these equations are true:
\(98 – 31 = Z\)
\(98 – Z = 31\)
\(Z + 31 = 98\)

Frequently Asked Questions
How many questions are on the 3rd grade MCAS Math test?
The full grade 3 MCAS has about 36-42 math questions across two sessions. This Top 10 set is a focused warm-up, not a full simulation, targeting the highest-yield grade 3 skills your child will see on test day.
Is a calculator allowed on the 3rd grade MCAS?
No. Massachusetts doesn’t allow calculators on the grade 3 math test. Your child needs multiplication facts through \(10\times 10\) memorized and should handle multi-digit addition, subtraction, and basic division by hand.
How long does the MCAS Math take?
The two real sessions run about 65-85 minutes each, with most third-graders finishing in 60-75 per session. Sessions are usually given on consecutive school days. This Top 10 set takes 15-20 minutes – one sitting.
What’s a passing score on the 3rd grade MCAS?
MCAS reports four performance levels: Not Meeting Expectations, Partially Meeting Expectations, Meeting Expectations, and Exceeding Expectations. Meeting Expectations is the on-grade-level mark schools target. There’s no automatic retention based on MCAS at grade 3.
Can my child retake the MCAS Math?
No. The grade 3 MCAS Math is given once per year in the spring. The spring score is the score of record. Schools provide added classroom support the next year if your child scores below Meeting Expectations.
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, basic measurement, and reading simple graphs.
How long should we study for the 3rd grade MCAS?
For an on-grade-level child, 4-6 weeks at 15-20 minutes a day is enough. For a child who needs more support, 8-12 weeks at 25 minutes daily. Multiplication-fact fluency is the single best investment of your prep time.
Where can we find more 3rd grade MCAS practice?
EffortlessMath offers a free MCAS Math sample set, a full-length MCAS Math practice test, additional question sets, and the Mastering Grade 3 Math workbook with worked examples for 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 state-specific clarifications. The major topics – multiplication, fractions, area, place value – match Common Core exactly.
How can I help my child prep at home?
Three habits beat anything fancy: (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 per weekend. Have your child write a sentence with the answer to constructed-response items – clear explanations earn full credit on MCAS.
