Everything you need to learn the 3 times table, from 3 × 1 = 3 to 3 × 12 = 36.
The 3 times table is the first one with a real rhythm to learn. The good news: every fact can be built from the 2 times table plus one more group.
3 × 7 = (2 × 7) + 7 = 14 + 7 = 21. Double the number, then add it once more.
Add the digits of any answer and you get 3, 6 or 9: 3 × 9 = 27, and 2 + 7 = 9. It’s a quick way to check an answer.
3, 6, 9 — 12, 15, 18 — 21, 24, 27 — 30, 33, 36. Clapping in groups of three makes the sequence stick.
3 × 7 = 21 and 3 × 8 = 24 are the usual stumbling blocks. Remember: there are 24 hours in a day, and 3 × 8 = 24.
