Secure knowledge and recognition of the digits 0-10 to work out missing numbers on both number track and number lines.

Pupils may not realise that a count with a missing number or number in the wrong place is incorrect.

Reinforce the stable order of counting to and from 10 and highlight clearly when the order is not correct or there is a number missing.

One more than - One more than is when there is a greater amount by one or another item in the set.
One less than - One less than is when there is a smaller amount by one or an item has been removed from the set.
Compare - When you compare you look for what is the same and what is different. It is good to know if one number is the same as, smaller than or bigger than another number.
Order - We can order numbers from the smallest to the largest or from the largest to the smallest. The order stays the same when you count.
