• I can count how many equal groups are shown in a picture

• I can say how many objects are in each group when the groups are equal in size

• I can describe a grouping using the phrase 'number of groups, of, group size', such as 3 groups of 2

• I can draw a model to match a description such as 2 groups of 4

Success Criteria

Lesson 1: The Language of Grouping

We are learning the language of grouping: how many groups there are, and how many are in each group.

• I can share a collection into groups of a given size and count how many groups are made

• I can find how many groups are needed when a fixed number of items goes in each group

• I can solve a 'how many groups' problem using materials or a drawing

• I can find all the equal group sizes that a small collection can be shared into

Success Criteria

Lesson 2: Grouping According to Group Size

We are learning to find how many equal groups can be made when we know how many go in each group.

• I can share a collection equally into a given number of groups

• I can count how many items end up in each group once the sharing is complete

• I can solve a 'how many in each group' problem using materials or a drawing

• I know that sharing into more groups means fewer in each group

Success Criteria

Lesson 3: Grouping According to How Many Groups

We are learning to find how many are in each group when we know how many equal groups to make.

• I can share a collection into equal groups and notice when some items are left over

• I know that the leftover amount is called a remainder

• I can state the remainder after sharing a collection into a given number of groups or a given group size

• I can explain why a remainder occurs, using the idea that there is not enough left to make another equal group

Success Criteria

Lesson 4: Finding Remainders

We are learning that sharing a collection into equal groups can sometimes leave some items over.

• I can identify the rows and the columns in an array

• I can make equal groups from an array by reading its rows

• I can make equal groups from an array by reading its columns

• I can state how many rows and columns an array has

Success Criteria

Lesson 5: Using Arrays for Grouping

We are learning to use rows and columns in an array to show equal groups.
