Common misconception

Children may not recognise given subtraction calculations that involve consecutive numbers and will resort to other strategies to calculate.

Recording equations alongside concrete or pictorial representations (such as cubes or a number line) will help children to visualise the difference and become more confident in spotting equations that contain consecutive numbers.

Keywords
