Lesson details

Key learning points

Each of the numbers six to ten can be partitioned into two parts in different ways.
A part-part-whole model or a bar model can be used to represent the whole and the parts.
If we know one part we can find the other part.
Knowing about odd and even parts means you know if the missing part is odd or even.

Common misconception

Pupils are not yet fluent in number pairs and partitions of numbers 6 to 10 and so rely on counting to find missing parts.

Develop subitising skills so that pupils are able to recognise small partitions instantly. Encourage choral repetition of stem sentences emphasising wholes and parts.

Keywords

Partition - To split a whole up into parts.
Whole - All of something. Complete.
Part - A piece or section of a whole.

Use real objects to partition numbers before moving to the abstract. Encourage systematic thinking, to find all possible combinations quicker and check that none have been missed. Use fingers to check the partitions of 10 Play the Up Down game where children say the number of fingers up or down.
