- Learn bonds to 10 first — they are the most useful facts in all of primary maths.
- Use fact triangles: write 3 numbers at corners — the top is always the sum of the two below.
- For timed drills, start with 2 minutes and reduce to 1 minute as fluency improves.
- Teach fact families together: knowing 3+4=7 automatically means knowing 4+3=7, 7-3=4, 7-4=3.
- Once addition facts are fluent, introduce the corresponding subtraction facts for the same number triples.
