We thought we had not received any suggestions for this activity but at the last moment from Adam at Anselm's we had these two contributions sent in. Thank you Adam.

This pattern is all the men doing the same thing at the same time (standing).

Cut four triangles from a square as shown in the picture. How many different shapes can you make by fitting the four triangles back together?

Can you make a rectangle with just 2 dominoes? What about 3, 4, 5, 6, 7...?

Arrange the shapes in a line so that you change either colour or shape in the next piece along. Can you find several ways to start with a blue triangle and end with a red circle?
