In this lesson, we will be combining sets, by counting all of the items in that set. We will practice writing addition equations.

In this lesson, we will continue to explore combining sets, by counting on from an amount. We will practice writing equations to express this.

This lesson will explore how addition can be linked to problem solving contexts. We will be applying the previously learnt strategies to solve problems.

In this lesson, we will explore commutativity - the concept that parts in addition equations can be added together in any order.

In this lesson, we will learn to subtract by partitioning a whole into parts.

In this lesson, we will practice subtracting by counting back in ones. We will do this with the support of a number line.

In this lesson, we will explore how subtraction can be linked to problem solving contexts. We will be applying the previously learnt strategies to solve problems.

In this lesson, we will explore how addition and subtraction are linked, and how a part whole relationship can produce related facts.

In this lesson, we will problem solve to complete missing number triangles! We will practice adding and subtracting to find the answers.

In this lesson, we will problem solve to uncover secret jumps! We will practice adding and subtracting to find the answers.
