How it works
Five is half of ten. Count in fives: 5, 10, 15, 20.
Ten times a number puts a zero after it: 10 × 3 = 30.
5 × 10 and 10 × 5 are the same.
Worked examples
Five tens
- 5 × 10 = ?
- Turn it around: 10 × 5.
- Ten fives or five tens: both are 50.
- So the answer is 50.
Ten times
- 10 × 3 = ?
- Ten times 3 is 3 tens.
- 3 tens is 30.
- So the answer is 30.
Five times one
- 5 × 1 = ?
- 5 × 1 is just 5.
- One group of 5.
- So the answer is 5.
