Model the activity below for pupils; list some possible descriptions of numbers, using the targeted vocabulary.
Pupils work in threes. One chooses a number from a set provided (e.g. 14, 24, 25, 40, 64, 99) and describes their number using either the word factor or multiple. The remaining pair of pupils select the possible numbers from the list and then devise their own question(s) to ensure they select the right number.
