Answers:
1- 860
We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Therefore, a rounded number of 855 to the nearest ten is 860.
2- A
\(\frac{12}{100}\) is equal to 0.12
3- A
7 days = 1 week
28 days \(= (28 ÷ 7)= 4\) weeks
4- C
Football teams should buy 14 uniforms and each uniform costs $24 so they should pay (14 \(×\) $24) $336.
Therefore, choice C is the correct answer:
\((24 × 10) + (24 × 4) =24(10+14) =24×14 = $336\)
5- C
These: \(98 – 31 = Z\)
\(98 – Z = 31\)
And \(Z + 31 = 98\) are equal.
6- A
This angle is less than \(90^\circ\). just choice A shows an angle less than \(90^\circ\).
7- B
Three–digit odd numbers that have a 6 in the hundreds place and a 3 in the tens place are 631, 633, 635, 637, 639. 637 is one of the alternatives.
8- D
Tam wants to divide his 390 cards into boxes of 30 cards. So he needs \(390÷30=13\) boxes.
9- C
Subtract hours: \(2 – 6 = -4\)
Subtract the minutes: \(15 – 30 = – 15\)
The minutes are less than 0, so:
• Add 60 to minutes ( \(-15 +60 =45\) minutes)
• Subtract 1 from hours \((-4 – 1 = -5)\) the hours are less than 0, add 24: \((24 – 5 =19)\)
The answer is 19:45 which is equal to 7:45
10- A

Frequently Asked Questions
What’s on the 4 grade MCAS Math test?
MCAS (Massachusetts Comprehensive Assessment System) Math at grade 4 follows the Massachusetts Curriculum Frameworks for Mathematics (the state’s adaptation of Common Core) and covers multi-digit multiplication and long division, fractions with like denominators, decimals to hundredths, perimeter and area, classifying two-dimensional figures, and multi-step word problems.
How many questions are on MCAS Math?
Grade 4 MCAS Math has roughly 40 items split across two sessions, given on separate days. Each session runs about 60-75 minutes. Most students finish well before time runs out – MCAS is not strictly timed at grades 3-8.
Is MCAS paper-based or computer-based?
Next-Generation MCAS is fully online for most Massachusetts students. Paper testing is available as a documented accommodation. Have your child practice on a Chromebook or tablet so the interface isn’t new on test day.
What question types appear on MCAS Math?
Multiple choice (selected response), multi-select, drag-and-drop, equation builder, short response (1-3 points), and one extended-response item per session where your child writes out reasoning. Constructed-response items count for roughly 25-30% of the total points.
Is a calculator allowed?
No – calculators aren’t allowed on grade 4 MCAS Math. Your child needs solid recall of basic facts and operations. A reference sheet is available on screen at grade 5 (and some grade 4 items) with formulas like area, perimeter, and volume.
What’s a passing score?
MCAS reports four levels: Exceeding Expectations, Meeting Expectations, Partially Meeting Expectations, and Not Meeting Expectations. “Meeting Expectations” is the state’s grade-level target. The grade-4 Math cut for Meeting is around 500 on the scale score (which runs 440-560).
When is MCAS given?
Next-Gen MCAS for grades 3-8 is given each spring, typically May through early June. Your district sets the exact schedule. The two math sessions usually happen within a one- or two-week stretch.
How is the extended-response item scored?
Extended-response items are scored 0-4 by trained scorers using a rubric. Partial credit is awarded for clear work even if the final answer is wrong, so encourage your child to show every step and write a sentence explaining their thinking.
How should we study for MCAS Math?
Three habits help most: (1) 15-20 minutes of focused practice four or five days a week, (2) one full-length practice test under realistic conditions a couple of weeks before testing, and (3) reviewing every missed item with your fourth grader to spot real gaps in understanding.
Where can my child get more MCAS practice?
