Lesson Details

Key learning points

The numbers 6 to 9 can be partitioned into 5 and a bit.
Where the whole is 6, 7, 8, or 9 it can be partitioned into one part of 5 and one smaller part.
A part-part-whole model can represent the five and a bit structure.

Common misconception

Children may rely on counting from 0 rather than seeing the five and a bit structure of the numbers 6 to 10 and may therefore not partition efficiently.

Use fingers to expose the 5 and a bit structure. 'Grow' a number by putting up fingers one at a time while counting, 'show it' by putting up the fingers all at once, 'throw it' as you quickly throw the number of fingers forwards.
