3 Times Table : multiplication, tricks and practice

The 3 times table introduces the first multi-digit answers and an elegant pattern: the digit sum of any multiple of 3 is itself a multiple of 3.

The full 3 times table, from 3×1 to 3×12

Here is the 3 times table in full. Read it both ways : 3×3 = 9, but also 9 = 3×3. It is the same operation, and it is what saves you time once you already know the earlier tables.

3 × 13
3 × 26
3 × 39
3 × 412
3 × 515
3 × 618
3 × 721
3 × 824
3 × 927
3 × 1030
3 × 1133
3 × 1236

Three tricks that make the 3 times table easier

1. The digit sum reveals a multiple of 3

Trick: 21 → 2+1 = 3, so 21 is in the table. 27 → 2+7 = 9, so 27 is too. This rule lets you quickly check whether a number is a multiple of 3, even beyond the table.

2. Add 3 on each line

The 3 times table goes up in 3s. If you know that 3×6 = 18, then 3×7 = 18 + 3 = 21. Useful when you get stuck: start from the previous answer and add 3.

3. Break it into the 2 times table + 1

3×n = 2×n + n. Example: 3×8 = 16 + 8 = 24. If you know the 2 times table, the 3 times table becomes a simple addition.

Quick check: every multiple of 3 has a digit sum divisible by 3. If you work out 3×9 = 28, check: 2+8 = 10, not a multiple of 3. Wrong. The correct answer is 27.

How to memorise the 3 times table in two weeks

Learning a times table is not about being clever, it is about spaced repetition. The brain holds on to information long-term when it reviews it just before forgetting, not by repeating it fifty times in one evening.

  1. Count in 3s out loud up to 36.
  2. Recite in order, then use the digit-sum rule to check.
  3. Practise out of order on the ones you get stuck on.

Frequently asked questions about the 3 times table

How do you learn the 3 times table quickly?

Count in 3s up to 36 out loud, twice a day for three days. Then use the digit-sum rule to check your answers: a multiple of 3 always has a digit sum divisible by 3.

How can you tell if a number is in the 3 times table?

Add up the digits of the number. If the sum is in the 3 times table (3, 6, 9, 12, 15...), then the number is a multiple of 3. Example: 24 → 2+4 = 6, so 24 is a multiple of 3.

At what age do you learn the 3 times table?

The 3 times table is introduced in Year 2 (age 6-7) in the UK and Grade 2 in the US, after the 2, 5 and 10 times tables.
