Doubles and make-a-ten tricks

A double is a number added to itself: 4 + 4 = 8. Know the doubles by heart and they help with others: 4 + 5 is one more than 4 + 4.

Worked example

3 + 3 = ?

Answer: 6

A double is a number and the same number again. Start at 3 and count on 3 more: 4, 5, 6. So 3 + 3 = 6.
