15 Times Table
Fifteen sits neatly between 10 and 20, and it splits into two of the friendliest tables there are: the 10 times table and the 5 times table.
Counting up in 15s: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150

The clever bit
Split 15 into 10 + 5
Fifteen splits beautifully because it is exactly 10 + 5, and both of those tables are already easy.
- 15 × 4 → (10 × 4) + (5 × 4) = 40 + 20 = 60
- 15 × 6 → (10 × 6) + (5 × 6) = 60 + 30 = 90
- 15 × 8 → (10 × 8) + (5 × 8) = 80 + 40 = 120
The 5-times half is always easy to spot: it is half of the 10-times half, since 5 is half of 10. Once the 10-times answer is known, just halve it and add.
The half-of-30 shortcut
Fifteen is also exactly half of 30, so doubling the number and using the 30 times table (or 3 times table with an extra zero) works too:
- 15 × 4 → 30 × 4 = 120, half of that is 60
Both routes land on the same answer — use whichever feels more natural.
One reassurance
Every fact in the 15 times table breaks into two facts a child already knows well: times 10, and times 5.

The ones people trip on
Most mistakes in the 15 times table land on these. Each one has a way in.
15 × 7 = 105
15 × 7 → 10 sevens are 70, 5 sevens are 35, and 70 + 35 = 105.
15 × 8 = 120
15 × 8 → 10 eights are 80, 5 eights are 40, and 80 + 40 = 120.
15 × 13 = 195
15 × 13 → 10 thirteens are 130, 5 thirteens are 65, and 130 + 65 = 195.
Where the 15 times table shows up
A quarter of an hour is 15 minutes. Four quarters make an hour, and a football match has two 15-minute halves in some youth leagues, so a full game is 2 × 15 = 30 minutes.
Questions parents ask
What is the easiest way to work out the 15 times table?
Split 15 into 10 + 5. Multiply by 10 (add a zero), multiply by 5 (half of times 10), then add the two together. For 15 × 6: 60 + 30 = 90.
Is there a shortcut using half of 30?
Yes. 15 is half of 30, so 15 × n is half of 30 × n. For 15 × 4: 30 × 4 = 120, and half of that is 60. Either method — 10 + 5, or half of 30 — gives the same answer, so use whichever feels faster.
What is 15 × 15?
225. Using the split: 10 fifteens are 150, 5 fifteens are 75, and 150 + 75 = 225.
Why does the 5 times table help with the 15 times table?
Because 15 = 10 + 5, and the 5 times table always ends in a clean 0 or 5. That makes the "plus 5 lots" half of the split fast to compute in your head.
