Times table tricks
Times 4 is doubling twice: 4 × 6 is double 12, which is 24. Times 3 is a double plus one more group.
Worked example
For grown-ups: Fact strategies by family: ×2 doubles, ×5 half of ×10, ×9 is ×10 − n, ×4 double-double, ×3 is ×2 + n, square facts, then the "hard 7s and 8s" via the distributive property. Below: three problems to try with the worked answers, and a free printable sheet. Children can practise the same skill as a game, with no sign-up and no ads.
