Find the missing part in an equation

Maths

Combine parts using the addition symbol

Understand that parts can be represented in any order

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

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

Using bar models to subtract

Understand the relationship between addition and subtraction

Understand addition as increasing a quantity

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.
