In this sequence students learn to use the array to determine how many are in a collection, using strategies such as skip counting, repeated addition and partitioning the array into smaller parts. Students recognise that some numbers can be represented as an array in different ways. They also see that some numbers cannot be represented as an array with two or more in each row and column.

This sequence is designed to introduce the array as a multiplicative structure. It is for students who:

- have had experience skip counting collections using different counts such as 2, 5 and 3.
- can create equal groups in a collection.
- are familiar with the concept of equal groups as representing multiplication.

### Lesson 1: Working with Arrays

Students are presented with a picture of the reSolve Fruit Shop and are asked to find examples of how multiplication can be used to find ‘how many?’ or ‘how much?’. Students explore how multiplication can be used to efficiently calculate how many pieces of fruit are in an array.

### Lesson 2: Lemon Arrays

Students arrange lemons into different arrays for display in the reSolve Fruit Shop. They explore arrays that can be made using 24 and 12 lemons, then work out all the ways the lemons can be arranged in arrays when split into two unequal groups.
