How to memorize times tables fast, up to 20

Times tables stick faster when you learn the easy tables first and repeat only the facts you miss, instead of chanting them in order. Because 6 × 8 and 8 × 6 have the same answer, only 36 of the 64 facts in the 2–9 tables are actually different.

The order to learn them

Build confidence with the easy tables, then use them to crack the harder ones.

OrderTableTrick
12s and 5s2s are doubles; 5s always end in 0 or 5
29sTimes 10, minus once: 9 × 7 = 70 − 7 = 63 (the digits always add to 9)
34sDouble the 2s: 4 × 7 → 14 → 28
43s and 6s6s = 5s plus one more: 6 × 7 = 35 + 7 = 42
58sDouble three times: 8 × 7 → 14 → 28 → 56
67sOnly 7 × 7 = 49 is new; the rest you already know

The facts most people miss

The usual sticking points are 6 × 7, 6 × 8, 7 × 8 and 8 × 9. Remember 7 × 8 = 56 as "5, 6, 7, 8" (56 = 7 × 8). Drill just these ten times a day and they come instantly within a week.

Tables 11 to 20: split them

You don't need to memorize up to 20. Split into 10 and the rest and use the tables you know: 17 × 6 = 10 × 6 + 7 × 6 = 60 + 42 = 102. 19 × 7 = 20 × 7 − 7 = 133.

A 5-minute daily routine

  • Pick only 2 or 3 tables
  • Solve 20 problems with the timer off
  • Retry only the ones you missed
  • When you get them all, turn the timer on and aim for 20 in under a minute
  • Add the next table the following day

FAQ

How long does it take to memorize times tables?
With 5 minutes a day, most learners recall the 2–9 tables instantly within 2 to 3 weeks. Keep repeating only the facts you miss.
What's the fastest way for kids to learn times tables?
Short daily rounds, easy tables first, and retrying only the misses. Chanting the whole table in order is slower.
Do I need to memorize tables up to 20?
Not really. Split them, like 17 × 6 = 60 + 42, and practice the few you use most.
I keep forgetting facts I learned.
Revisit the missed facts every few days. Short daily practice sticks better than one long session.
