Understand the use of the equals sign in equations

Understanding part-part-whole relationships

Add parts to find the value of the whole and write the equation

Find the missing part in an equation

Partition a whole into two parts and write as a subtraction equation

Using bar models to subtract

In this unit pupils will combine 2 or more parts to make a whole. They will learn addends are represented in any order and the = sign shows the whole and sum of the parts are equal. In the future unit pupils will find missing addends. They will partition a whole into 2 parts representing first, then, now stories with subtraction equations. They will learn + and - are inverse operations.

In prior learning, pupils will have learnt to count confidently and have developed a deep understanding of the numbers to 10, the relationships between them and the patterns within those numbers. In this unit pupils will combine two parts to make a whole, learn that addends are represented in any order and learn that the equals sign shows that the whole and the sum of the parts are equal.
