Know that addition and subtraction are inverse operations

Represent the inverse relationship between addition and subtraction

In this unit pupils will find missing addends in equations. They will partition a whole into 2 parts representing first, then, now stories with subtraction equations. They will learn + and - are inverse operations. In the future unit pupils will explain that addition is commutative. They will find pairs of numbers to 10 and add or subtract 1 from any number.

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 find missing addends. They will partition a whole into two parts and represent it with subtraction equations learning that addition and subtraction are inverse operations.

To make something smaller in size or quantity.

To partition one part from another (the subtrahend from the difference), or to decrease an amount by taking an amount away.

Make something smaller in size or quantity decrease.

To find the total, or sum, by combining two or more parts (addends), or to increase an amount by adding another.

To make something greater/larger in size or quantity.

Make something larger / greater (in size or quantity).

To find the total, or sum, by combining two or more parts, or to increase an amount by adding another.

To partition one part from another, or to decrease an amount by taking an amount away.

o find the total, or sum, by combining two or more parts (addends), or to increase an amount by adding another.
