Key learning points
- The numbers 11-19 can be formed by combining a ten and ones.
- The numbers 11-19 can be partitioned into a ten and ones.
- Tens frames can be used to represent the numbers 11 to 19

Ones - Individual objects, grouped in ones.
Common misconception
Pupils use one to one correspondence to count all rather than counting on from a group of 10 to identify a teen number.
Provide concrete and pictorial examples where it is more difficult to count the ones in a group of 10 e.g. a bundle of straws or box of pencils. Encourage pupils to use the phrase 'one ten and ...' to focus attention on counting on from 10
