Answers:
1- C
\(6\) quarters \(= 6 × 25\) pennies \(=150\) pennies
\(9\) dimes \(= 9 ×10 \)pennies \(= 90\) pennies
In total Nicole has 251 pennies
2- A
\(1\) issue\(= $4\)
How many issue? \(= $72\)
\($72 ÷ $4= 18\) issue
3- C
Use perimeter of triangle formula.
\(P = a + b + c\)
\(P = 12 + 15 + 16 = 43\) inches
4- C
Use perimeter of rectangle formula.
\(P = 2(L + W)\)
\(60 = 2(10+W) ⇒ 2W = 40 ⇒ W = 20 \)feet
5- B
An obtuse triangle is one with one obtuse angle (greater than 90\(^\circ\)) and two acute angles. Since a triangle’s angles must sum to 180\(^\circ\), no triangle can have more than one obtuse angle.
6- C
\(1\) foot \(= 0.333 \)yard
So \(36\) foot \(= 12\) yards \((36 × 0.33)\)
7- B
The sum of \(A\) and \(B\) equals \(35: A + B = 35\), if \(A = 16\) we have \(16 +B = 35\)
8- D
\(A = 108 ÷ 9 = 12\)
9- B
Sum of these three angle are 180\(^\circ\).
\(A^\circ + 80^\circ + 16^\circ = 180^\circ\)
\(A^\circ =180^\circ – 96^\circ = 84^\circ\)
10- C
Use perimeter of trapezoid formula.
\(P = a + b + c + d\)
\(P = 2+ 6 + 2+ 8 =18\)
11- B
Low temperature is 24\(^\circ\)f cooler than the temperature at 12:00 PM that is 76of, that means low temperature is 52\(^\circ\)f (76\(^\circ\)f \(-\) 24\(^\circ\)f) that is close to choice B
12- A
\((4 × 10) + (7 × 1) + (6 × 0.01) = 40 + 7 + 0.06 = 47.06\)
13- D
1 year \(=\) 365 days, 1 day \(=\) 24 hours
1 year \(=\) 365 × 24
1 year \(=\) 8,760
14- B
Each game = \(\frac{11}{2}\) hours = 90 minutes so 3 games = \(\frac{41}{2}\) hours = 270 minutes
5minutes between each game, so there is 10 minutes in total between 3 games.
She arrives 15 minutes before first game and left 10 minutes after the last game.
In total she was \(270+10+15+10 =305\) minutes at the soccer field.
15- A
You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here the first shape shows a line of symmetry.
16- B
Find the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.
LCD of 2, 8, 4 and 16 is 16. Rewrite the input fractions as equivalent fractions using the LCD:
A. \(\frac{8}{16}\)
B. \(\frac{6}{16}\)
C. \(\frac{12}{16}\)
D. \(\frac{9}{16}\)
So choice B has the least value.
17- D
12 pastilles\(=\) 1 box
336 pastilles\(=\) (\(336 ÷12 = 28\)) boxes
18- 64
Use volume of cube formula:
V\(=a^3\)
V\(=4^3 =64\)
19- C
Arrow shows exactly the middle of two numbers 25 and 35, so the answer is 30
20- A
This shape shows 3 complete shaded triangles and a half of a triangle that is equal to \(3\frac{1}{2}\)

Frequently Asked Questions
How many questions are on the 4th Grade MCAS math test?
The real MCAS Grade 4 math has about 36-42 questions split across two sessions, each lasting around 60-75 minutes. Most are multiple choice or technology-enhanced (drag-and-drop, equation editor), plus a couple of short-response and open-response items. Our practice set has 20 of the most common types.
Is a calculator allowed on the 4th Grade MCAS?
No. Calculators are not allowed on the Grade 4 MCAS math test. Massachusetts permits calculators starting in grade 6 on the calculator-allowed section only. Your fourth grader should practice multi-digit arithmetic by hand.
What’s a passing score on the 4th Grade MCAS?
MCAS reports 4 performance levels: Not Meeting Expectations, Partially Meeting Expectations, Meeting Expectations, and Exceeding Expectations. “Meeting Expectations” is the on-grade-level target and corresponds to a scaled score of 500 on the math test.
When is the MCAS given?
The Grade 4 MCAS math is given in April or May each year. The state sets the testing window, and your district picks the exact days within it. Your child’s school sends home a testing schedule a few weeks in advance.
How is the MCAS Grade 4 math scored?
Each session is scored, then combined into a single scaled score (roughly 440-560 at grade 4) and one of 4 performance levels. Open-response items get hand-scored; everything else is auto-scored. Reports usually arrive over the summer or in early fall.
Can my child retake the MCAS?
The Grade 4 MCAS is given once a year with no in-year retake. (The high school MCAS has retake windows, but those don’t apply at elementary grades.) If your child scores below Meeting Expectations, the school may add support and your child will take a fresh MCAS in grade 5.
What math topics are on the 4th Grade MCAS?
Massachusetts uses the 2017 Massachusetts Curriculum Framework, which mirrors Common Core Grade 4 closely. Topics include place value, multi-digit multiplication and division, fractions (equivalent fractions, fraction operations with like denominators, multiplying fractions by whole numbers), decimals to hundredths, area and perimeter, angle measurement, and basic geometry.
How long should we study for the 4th Grade MCAS?
About 6-8 weeks of light practice (15-20 minutes a day, 4 days a week) covers it for most kids. Start with a diagnostic, focus on the 2-3 weakest topics, then add full timed practice in the final 2 weeks. Daily short practice beats weekend cramming.
Where can I find more 4th Grade MCAS practice?
EffortlessMath has free lessons for every Grade 4 Common Core math topic (the MCAS standards mirror Common Core), plus the Common Core Mathematics Workbook for Grade 4 and a grade-4 practice test bundle. The related lessons below cover MCAS’s highest-frequency topics.
Is the MCAS aligned with Common Core?
Yes. The 2017 Massachusetts Curriculum Framework was built on Common Core with about 90% overlap. Common Core Grade 4 prep materials work very well for MCAS preparation.
