This resource is aimed at pupils in middle classes or SEN pupils. It is based on reinforcing the concept of hundreds, tens and units. The pack contains 20 cards: on the right hand side of each card are four numbers – the tens and units are the same, only the hundreds are different. This should make it easier for the pupil to identify the smallest number. The pupil has to use a clothes peg to indicate which they think is the smallest of the four numbers.
