Zero is the number that represents no amount or objects. When we add zero to a number, the result is just the number, unchanged.

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

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

The equal sign is used to show that the values on either side of it are the same.

Addition and subtraction facts within 10

In this 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 the future unit pupils will demonstrate their fluency of addition and subtraction within ten. They will practise addition and subtraction strategies.

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 explain that addition is commutative. They will find pairs of numbers that total 10 and add or subtract 1 to and from any number to 10.

In this unit pupils will explain that addition is commutative. They will find pairs of numbers to 10 and add or subtract 1 from any number.¬†Pupils will also develop their knowledge and understanding of odd and even numbers and that even numbers relate to doubling and halving.
