3rd Grade Math Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026
Third grade is the year multiplication and division arrive, and fractions become real numbers on a number line. Children also meet area and perimeter for the first time. This quiz samples all of those, and because the questions are generated fresh each time, your child can practise the times tables without memorising a single sheet of answers.
What this quiz covers
- Multiplication facts up to 10 × 10
- Division as the inverse of multiplication
- Comparing fractions with the same denominator
- Area of a rectangle
- Perimeter of a rectangle
- Rounding to the nearest hundred and finding factors
How to prepare
Fluency with the times tables unlocks almost everything that follows. Practise a few minutes a day and start with the easier tables (2, 5, 10) before the harder ones (6, 7, 8). Remind your child that division is just multiplication turned around: if 6 × 7 = 42, then 42 ÷ 7 = 6.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- 4 × 9 = ?
Show answer
36. 4 × 9 = 36.
- 6 ÷ 3 = ?
Show answer
2. 6 ÷ 3 = 2 because 3 × 2 = 6.
- Which fraction is larger: 1/8 or 4/8?
Show answer
4/8. The denominators match, so the larger numerator wins: 4/8.
- A rectangle is 8 cm long and 4 cm wide. What is its area?
Show answer
32 cm². Area = length × width = 8 × 4 = 32 cm².
- A rectangle is 11 cm long and 4 cm wide. What is its perimeter?
Show answer
30 cm. Perimeter = 2 × (11 + 4) = 30 cm.
