Free 4th Grade MAP Math Practice Test with Answers
Fourth grade is where the numbers get bigger and fractions stop being pictures. Multiplication moves to two digits by two digits, division starts leaving remainders that have to mean something, and decimals arrive for the first time, introduced as another way of writing tenths and hundredths rather than as a new topic.

Sample grade 4 questions
Sample question 1 · Understand 10× place value relationship
Which of these numbers has a 2 whose value is ten times the value of the 2 in 1,728?
- 2,715
- 8,233
- 8,921
- 7,332
Show the answer and explanation
Answer: 8,233.
The 2 in 1,728 is worth 20. Ten times that is 200, so the 2 must be one place to the left — in 8,233.
Sample question 2 · Solve multiplicative comparison word problems
The price of a bicycle is $75. The price of the bicycle is 5 times as much as the price of a helmet. What is the price of the helmet?
- $70
- $375
- $80
- $15
Show the answer and explanation
Answer: $15.
The helmet costs 75 ÷ 5 = $15. The trap is $375 — multiplying when the unknown is the SMALLER amount.
Sample question 3 · Identify line symmetry
How many lines of symmetry does an equilateral triangle (all three sides equal) have?
- 3
- 1
- 2
- 0
Show the answer and explanation
Answer: 3.
An equilateral triangle has 3 lines of symmetry, one from each vertex to the midpoint of the opposite side.
Sample question 4 · Compare fractions with different denominators
Two recipes use vanilla. The first uses 3/4 of a teaspoon and the second uses 3/5 of a teaspoon. Which comparison is true?
- 3/4 > 3/5
- 3/4 < 3/5
- 3/4 = 3/5
Show the answer and explanation
Answer: 3/4 > 3/5.
Both fractions count 3 pieces, but the pieces are different sizes. Splitting a whole into 4 parts (fourths) makes bigger pieces than splitting it into 5 parts (fifths). Since each fourth is bigger than each fifth, 3 fourths is more than 3 fifths. So 3/4 > 3/5.
Sample question 5 · Read, write, and compare multi-digit numbers
What is three hundred eighty thousand, five hundred ninety written in standard form?
Your answer
Show the answer and explanation
Answer: 380,590 (also accepted: 380590).
three hundred eighty thousand, five hundred ninety is 380,590. The trap is the zeros — "three hundred eighty thousand, five hundred ninety" must keep every place, even empty ones (e.g. a missing tens digit becomes 0).
Sample question 6 · Add and subtract fractions with like denominators
Omar used 6/10 cup of flour in the morning and 1/10 cup more in the afternoon. How much did Omar use in all?
Use a slash ( / ) to separate the numerator and denominator.
Your answer, as a fraction
Show the answer and explanation
Answer: 7/10.
6/10 + 1/10 = 7/10 cups in all. Keep the denominator — the pieces are already the same size.
Sample question 7 · Compare decimals to hundredths
Put the decimals in order from SMALLEST to LARGEST.
- 0.93
- 0.25
- 0.74
- 0.05
Show the answer and explanation
Answer: 1. 0.05, 2. 0.25, 3. 0.74, 4. 0.93.
In order: 0.05 < 0.25 < 0.74 < 0.93. Compare by place value, not by how many digits each decimal has.
Sample question 8 · Generate and analyze patterns
The rule is "multiply by 4". Complete the output column.
| In | Out (× 4) |
|---|---|
| 2 | 8 |
| 5 | |
| 7 |
Show the answer and explanation
Answer: 20, 28.
| In | Out (× 4) |
|---|---|
| 2 | 8 |
| 5 | 20 |
| 7 | 28 |
The rule says to multiply each input by 4. Row 1: the input is 5, and 5 × 4 = 20. Row 2: the input is 7, and 7 × 4 = 28. The completed output column has 20 in row 1 and 28 in row 2.

What grade 4 math covers
Five areas, and they do not carry equal weight.
Fractions and decimals. Equivalent fractions, comparing ones with different denominators, and adding when the denominators match. Then tenths and hundredths get written a second way, and your child has to see 0.7 and 7/10 as the same thing. That link is the year's quietly important idea.
Place value and multi-digit arithmetic. Reading, comparing and rounding large numbers, then multiplying two digits by two digits and dividing a four-digit number. Place value is what makes those methods work rather than being magic.
Multiplicative thinking. The shift from "5 more than" to "5 times as many," which is a genuinely different comparison and catches a lot of fourth graders out. Also factors and multiples, and word problems where the remainder has to be interpreted rather than dropped.
Measurement and data. Converting units, area and perimeter of rectangles, and angles: what they are, how to measure them, how they add.
Geometry. Lines and angles, classifying shapes by their sides, and symmetry. The lightest of the five, and often taught last.
If two-digit multiplication is automatic and decimals feel like fractions rather than a separate system, the year usually goes well.
What the right answers don't show
Two of the questions ask the same thing in different clothes. One gives four decimals, 0.7 and 0.07 and 0.77 and 0.17, and asks for them in order. Plenty of fourth graders sort those by reading the digits after the point as whole numbers, which puts 0.07 first and looks like carelessness rather than what it is. The other draws a number line split into twelfths and asks for 2/3 and 3/4 to be placed on it. There is nowhere to hide on a number line.
That gap between knowing a procedure and knowing what the number means is what we call fluent but fragile, and it is the crack that widens into fifth-grade fraction trouble.
One more is worth watching. It asks your child to compare 30,500 with 30,500. They are equal, and a surprising number of children reach for the greater-than sign anyway, because comparison questions have trained them to expect a winner.
Is your fourth grader ready for fall MAP testing?
Most schools give MAP Growth in a fall window, often late August into September. A fourth grader's fall score leans heavily on third-grade foundations, multiplication facts and place value and the first ideas about fractions, as much as on new fourth-grade material.
Fourteen questions is a spot-check. The Helix diagnostic adjusts across many more skills and several difficulty levels, and comes back with a skill-by-skill map of what is secure, what is developing, and what to work on first.
Which grade should I choose?
Choose the grade whose material you want to practice. For review before a new school year, choose the grade your child just completed. Grade labels describe the material, not your child's ability.
