How to use this worksheet
- For each problem, ask the multiplication question: for 21 ÷ 3, "3 times what makes 21?" It is 7.
- Solve problems 1 to 10; their answers are the numbers 1 to 10, each once, which makes a quick self-check.
- Problems 11 to 20 repeat all ten facts in a new order, so the same self-check works again.
- Compare with the answer page and practice the multiplication fact behind every mistake.
What this worksheet teaches
Each problem divides a multiple of 3, from 3 to 30, by 3, so there are no remainders and the answers run from 1 to 10. Every fact appears exactly twice. Division by 3 is the reverse of the 3 times table, so practicing both together links them into one family of facts.
The digit-sum test for 3
A number can be divided by 3 without a remainder when its digits add up to 3, 6, 9 or another multiple of 3. For 27, 2 + 7 = 9, so it divides by 3 (27 ÷ 3 = 9). For 24, 2 + 4 = 6, so it does too (24 ÷ 3 = 8). Every number divided on this page passes the test, which children can check themselves.
