Books 18, 19 and 20 cover 27 learning intentions for children aged about 9 to 11 years old.

At this level, students are learning to choose the best way to solve an addition or subtraction problem from a range of strategies. They see numbers as ‘whole’ units but also understand that ‘nested’ within these units is a range of possibilities for partitioning (breaking up) and recombining. This is called part-whole thinking.

Using compensation: 30 + 27 or 30 + 28 – 1

Using place value partitioning: 29 + 20 + 8

or 20 + 20 + 9 + 8.
