Matching activities will generate discussion and help pupils identify equivalent calculations. Give pupils sets of cards to match to given answers, e.g. 72, 7.2, and 0.72. Calculation cards with calculations might include, for example:
72 × 0.1
720 × 0.01
72 ÷ 10
etc.
Ask pupils whether they expect the answer to be larger or smaller than the original number and by how many places.
Use a spider diagram with a number such as 6.3 at the centre. Ask pupils to devise relevant multiplications and divisions that have this answer.
