3rd Grade Understanding Division Quiz: 10 Questions with Explanations

A \(18 \times 3 = 54\)B \(18 – 3 = 15\)C \(18 \div 3 = 6\)D \(18 + 3 = 21\)

Sharing equally is division. Multiplying, subtracting, or adding does not split the total into equal parts.

A 5B 15C 4D 25

There are 5 equal groups, and 20 ÷ 5 = 4. Counting the groups gives 5, which is not the size of a group.

A 24B 30C 8D 9

27 ÷ 3 = 9 because 3 × 9 = 27. Subtracting 3 gives 24 and adding 3 gives 30.

A \(5 + ? = 35\)B \(35 \times 5 = ?\)C \(? \div 35 = 5\)D \(5 \times ? = 35\)

Division asks for a missing factor, so 35 ÷ 5 matches 5 × ? = 35.

A 5B 4C 9D 27

36 ÷ 9 = 4. The picture has four jumps. Counting the ticks gives 5 by mistake.

A 7B 48C 64D 6

8 × 7 = 56. Subtracting 8 gives 48 and adding 8 gives 64.

A 10B 24C 2D 18

The total is 6 × 4 = 24. Adding gives 10 and subtracting gives 2.

A 6B 40C 56D 8

8 × 6 = 48, so the unknown is 6. Subtracting 8 gives 40 and adding 8 gives 56.

A 24B 7C 32D 8

28 ÷ 4 = 7 because 4 × 7 = 28. Subtracting 4 gives 24 and adding 4 gives 32.

A \(42 \div 6 = 7\) because \(6 \times 7 = 42\)B \(42 \div 6 = 8\) because \(6 \times 8 = 42\)C \(42 \div 6 = 36\) because \(42 – 6 = 36\)D \(42 \div 6 = 48\) because \(42 + 6 = 48\)

Check a quotient by multiplying it by the divisor. 6 × 7 = 42, but 6 × 8 = 48.
