Use three sheets of paper that are the same size. Fold the first piece of paper into 2 equal pieces. Label each half and colour in one half. 1 2 Fold the second piece of paper in half and then in half again. Now you have quarters. 1 Label each quarter 4 and colour in two quarters. Now compare it to the half that you coloured. What do you notice? Fold the third piece of paper in half, then in half again. What fraction do you have now? How many parts will you have to colour to be the same as the other 2?
