Stage 2: The Number Line
Children use number lines and practical resources to support calculation and teachers demonstrate the use of the number line. Count on and back and use terms such as “find the difference”.
The number line should also be used to show that 6 - 3 means the ‘difference between 6 and 3’ or ‘the difference between 3 and 6’ and how many jumps they are apart.
Children then begin to use numbered lines to support their own calculations - using a numbered line to count back in ones.
