This resource is aimed at pupils in middle classes or SEN pupils. It is based on reinforcing the concept of place value of hundreds, tens, units. The pack contains 16 cards – on the left hand side of each card is a three digit number, with one digit underlined and highlighted in red. The pupil has to decide whether the underlined digit is a hundred, a ten or a unit and place a clothes peg on the appropriate word on the right hand side of the card.
