How to make three-digit numbers, starting with one number and placing another next to it in order to make a new number. For example, 3, 33 and 333.
This clip can be used to encourage pupils to experiment with making their own three-digit numbers. Pupils could be given a range of cut-out digits and asked to make as many three-digit numbers as they can. This can lead into an early introduction to place value, with the magic digit 3 (or any other number for that matter) moving its way all around other numbers and shown to be changing its value each time, making the numbers get bigger and smaller. Pupils can then be instructed to use the magic digit to create two different numbers, one big, one small.
