Your Task – Work in Pairs Choose a question. Cut it out. Stick it on your A4 paper. Answer it using boxing up. Each pair should aim to complete two questions so that you all have an example to stick in your Maths books. You may end up doing the same question twice when it is your turn to train someone else.

You can tell them what each box is for but you should ask them what goes inside. Try not to give any answers, try to get the answers from them through questioning. Be supportive / positive. Rules for Explaining
