Use squared-paper - 1 or 2 cm squares are about the right size.
Each of the shapes given below is to be cut out from the squared-paper and then cut up into separate pieces as shown by the coloured areas inside each shape.
For each shape, find how to re-arrange its separate pieces so as to to make a square. It is best to work on the shapes one at a time to avoid mixing up all the separate pieces.
