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 .
