How to use this worksheet
- Before problem 1, draw 4 × 5 as four circles with five dots in each and count the dots together: 20.
- Solve the problems in number order; skip counting out loud (5, 10, 15, 20) is fine at this stage.
- When you reach problem 8, 3 × 6, look back at problem 7, 6 × 3, and compare the answers.
- Check with the answer page.
What this worksheet teaches
Every product on this page is 20 or less, so the facts come mostly from the 2, 3, 4 and 5 times tables. Children learn that multiplication means equal groups, a faster way to add the same number repeatedly. The page mixes square facts (2 × 2, 3 × 3, 4 × 4), four facts with 1 (1 × 5, 10 × 1, 1 × 1, 2 × 1) and turnaround pairs, a good base before whole tables.
Multiplication as equal groups
Four groups of five, five groups of four and two groups of ten all make 20, and all three appear here as 4 × 5, 5 × 4, 2 × 10 and 10 × 2. Drawing a problem as an array of dots makes the turnaround rule visible: 3 rows of 6 dots, turned sideways, become 6 rows of 3, and the number of dots does not change.
