Explain that objects can be shared equally

Use skip counting to solve a sharing problem

Skip count to find the group size in a sharing problem

Solve a variety of division problems, explaining understanding

In this unit pupils will explain when objects can and cannot be grouped or shared equally. In the future unit pupils will learn how to find the quotient for 2x 5x 10x tables. They will learn how a division equation with 2 as a divisor is related to halving and each part of a division equation and how they can be interchanged. They will use divisibility rules to solve problems.

In the prior unit pupils learned how a multiplication equation with 2 as a factor related to doubling and how a division equation with 2 as a divisor related to halving. They explained the relationship between factors and products. In this unit pupils will explain when objects can and cannot be grouped or shared equally.

In this unit pupils will use practical resources to model and explain when objects can and cannot be grouped or shared equally. They will then represent practical situations using division expressions and equations.
