Tips for Learning Addition Facts

Master the doubles

2+2, 3+3, 4+4… Doubles are easy to visualise (think of pairs of shoes, hands, etc.) and serve as anchors for nearby facts.

Make 10

Learn all pairs that add up to 10 (1+9, 2+8, 3+7, 4+6, 5+5). This is the most powerful addition strategy and helps with mental math for life.

Doubles +1 / −1

If you know 6+6=12, then 6+7 is just one more: 13. This 'near doubles' trick covers many facts.

Counting on

For small additions, start from the larger number and count up. For 3+8, start at 8 and count: 9, 10, 11.

The turn-around trick

3+7 = 7+3. Addition is commutative - you only need to learn half the table!

Use a number line

Drawing a number line and hopping forward helps visualise addition. It builds number sense naturally.
