4th Grade Math Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026
Fourth grade stretches arithmetic into larger numbers. Children multiply two-digit numbers, add fractions with matching denominators, and describe numbers using factors and multiples. Geometry adds measuring and calculating angles. The questions below reflect that range, with an explanation after each answer.
What this quiz covers
- Multiplying a two-digit number by a one-digit number
- Multiplication and division facts to 12
- Adding fractions with like denominators
- Place value up to the thousands
- Factors and multiples
- Complementary and supplementary angles
How to prepare
When multiplying larger numbers, split them by place value: 47 × 6 is 40 × 6 + 7 × 6 = 240 + 42 = 282. For factors, work in pairs from the outside in (1 × 24, 2 × 12, 3 × 8, 4 × 6). Keep a small angle cheat sheet: 90° for complementary, 180° for supplementary.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- 36 × 8 = ?
Show answer
288. 36 × 8: 36 × 8 = 288.
- 3 × 3 = ?
Show answer
9. 3 × 3 = 9.
- 12 ÷ 3 = ?
Show answer
4. 12 ÷ 3 = 4 because 3 × 4 = 12.
- 5/8 + 1/8 = ?
Show answer
3/4. Add the numerators and keep the denominator: (5 + 1)/8 = 6/8 = 3/4.
- In 8,878, which digit is in the hundreds place?
Show answer
8. The hundreds digit of 8878 is 8.
Frequently asked questions
