Partition means to split up a whole into parts.

A part-part-whole model is a pictorial representation that shows the whole and its parts.

Any way two or more parts can be put together.

Having an order to the way we work, identifying and using patterns.

A way of showing information (such as numbers and descriptions), arranged in rows and columns.

Partition the numbers one to five in a systematic way

Maths

In this unit pupils will revisit how numbers are represented cardinally and ordinally. They will partition 1 - 5 in different ways and find a missing part. In the future 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 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 partition 1 to 5 in different ways and find a missing part.

Composition of numbers 0 to 5
