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.

Introduction to division structures

4 children get into pairs. Are the groups equal or unequal?

6 children get into groups with 3 children in each group. Are the groups equal or unequal?

There are 8 children. Which equal-sized groups could they get into without any children being left out?

There are 7 children. They get into pairs. How many children are not in a pair? {{ }}

There are 9 children. They get into groups with 4 children in each group. How many children are not in a group of 4? {{ }}

 There are {{ }} children. They get into 2 groups with 5 children in each group. 1 child is not in one of these groups. How many children are there altogether?

Look at the counters. How many counters are there in each group? {{ }} counters

Look at the bar model. How many groups of 2 does it represent? {{ }} groups

Look at the equation. Match each number with what it tells us.
