11. 15 × 11 = 165
12. 15 × 12 = 180

Bigger: 15 × 13 to 15 × 20

1. 15 × 13 = 195

The trick for the 15 times table: 10 times plus half of it

15 is 10 + 5, and 5 is half of 10. Multiply by 10, then add half of that.

• 15 × 6: 10 × 6 = 60, half is 30, 60 + 30 = 90
• 15 × 8: 10 × 8 = 80, half is 40, 80 + 40 = 120

Patterns in the 15 times table

• Every answer ends in 5 or 0.
• 15, 30, 45, 60: the minutes in a quarter, half, three quarters and a full hour.
• Every second answer is in the 30 times table: 15 × 2 = 30, 15 × 4 = 60.
• Each answer is 3 times the 5 times table answer.

Saying the table out loud helps too: fifteen times one is 15, fifteen times two is 30…

1. Fifteen times one is 15.
2. Fifteen times two is 30.
3. Fifteen times three is 45.
4. Fifteen times four is 60.
5. Fifteen times five is 75.

See the 15 times table

Draw these with your child. Each one shows that multiplying by 15 means counting equal groups of 15.

Facts you already know

Learn it after the 1 to 12 tables. You do not need new facts: every fact splits into a 10 times fact and a fact you already know.

For example, 15 × 6 = 10 × 6 + 5 × 6 = 60 + 30 = 90. Children who know the 1 to 12 tables can work out every 15 times fact this way, and with practice the answers become memorised.

The table also works backwards as division: 45 ÷ 15 = 3 · 105 ÷ 15 = 7 · 180 ÷ 15 = 12.

In real life: There are 15 minutes in a quarter of an hour. How many minutes in 3 quarter hours? 3 × 15 = 45.

The 15 times table as division facts

Every multiplication fact has a division fact hiding inside it. If 15 × 6 = 90, then 90 shared into groups of 15 makes 6 groups. Here are the division facts for the table of 15:

1. 15 ÷ 15 = 1
2. 30 ÷ 15 = 2
3. 45 ÷ 15 = 3
4. 60 ÷ 15 = 4
5. 75 ÷ 15 = 5
6. 90 ÷ 15 = 6
7. 105 ÷ 15 = 7
8. 120 ÷ 15 = 8
9. 135 ÷ 15 = 9
10. 150 ÷ 15 = 10
11. 165 ÷ 15 = 11
12. 180 ÷ 15 = 12

Four facts with the same three numbers make a fact family.

15 × 7 = 105 · 7 × 15 = 105 · 105 ÷ 15 = 7 · 105 ÷ 7 = 15

Learning the table this way means your child learns division at the same time. To check a division answer, multiply back (see check division with multiplication).

Multiples of 15

The answers in the 15 times table are the multiples of 15. They go on forever: 15, 30, 45, 60, 75, 90, 105, 120… Every multiple of 15 can be split into equal groups of 15 with nothing left over.

Is it a multiple of 15? A number is in the 15 times table if it ends in 0 or 5 and its digits add up to a multiple of 3. Try it on 255: it is 15 × 17. Older children use these tests to find factors and multiples and to simplify fractions.

15 times table word problems

Word problems show your child when to use the table. Read each one aloud, ask “how many groups, and how many in each group?”, then multiply.

1. Groups to total. How many minutes in 6 quarter hours? There are 6 groups of 15, so 6 × 15 = 90 minutes.
2. Total to groups. 135 minutes are put into groups of 15. How many groups? Ask “15 times what is 135?” The answer is 9.
3. Two steps. Count the minutes in 4 quarter hours, then in 3 more. That is 60 + 45 = 105. Quicker: 4 + 3 = 7 groups, and 7 × 15 = 105.

A 5-day plan for the 15 times table

1. Day 1: learn the trick (10 times plus half of it) and say the table forwards.
2. Day 2: say it backwards, then answer the practice questions in order.
3. Day 3: mixed order, with extra time on 15 × 7 and 15 × 8.
4. Day 4: missing numbers and division: 15 × ? = 120 and 120 ÷ 15.
5. Day 5: the 1-minute challenge, then the worksheet.

Five minutes a day is enough. A fact is learned when the answer comes in about 3 seconds without counting. Come back to the table once a week after that, so it stays fresh.
