Secure the sequence of numbers to and from 20.
Practice one to one correspondence with actions and objects counting forwards and backwards.
Use understanding of the sequence of numbers to 20 to count on and back from different starting points securely.

Failing to match one count to one action.

Slow the counting and make the action and count very deliberately at the same time so pupils can imitate the modelling.

One more - The number that comes next in the count is one more than the previous number.
Next - The next number is one more than the previous number.
One fewer - The number that comes before in the count is one fewer than the previous number.
Before - The number before is one fewer than the previous number.
