One more than is when there is a greater amount by one or another item in the set.

One less than is when there is a smaller amount by one or an item has been removed from the set.

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.

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.

Maths

In this unit pupils will review their knowledge from the EYFS with counting to and from 10. They will compare and order numbers to 10 practically and will consider the role of zero to represent nothing. In the future unit pupils will  consolidate counting to 20 and back. They will secure their understanding of the teens numbers and their understanding of these numbers in an ordinal context

In prior learning, pupils will have learnt to count confidently and have developed a deep understanding of the numbers to 10, the relationships between them and the patterns within those numbers. In this unit pupils will review their knowledge from the EYFS with counting to and from 10, comparing and ordering numbers to 10 and considering the role of zero.
