To find a value that is close enough to the right answer, usually with some thought or calculation involved.

You compare to find out what is the same and what is different. You can compare numbers to find out if one is greater than or less than another.

The middle of something. The point halfway along.

A line with numbers placed in their correct position.

Estimate where 6, 7, 8 and 9 lie on an unmarked number line

Maths

In this unit pupils will represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into 2 parts. In the future unit pupils will explain 11-19 cardinally and ordinally. They will double and halve numbers 6-9. They will add and subtract within 20.

In prior learning, pupils will have explored the composition of numbers to 10 and be able to subitise up to 5. In this unit pupils will represent numbers 6 to 10 by partitioning in different ways and learn what odd and even numbers are and how they can be partitioned.
