What about shape 3? How many of shape 2 will fit into shape 3?
Try and find out how many pieces of shape 1 and shape 2 fit into shape 7.
I learnt of Van Hiele' s theory of geometric thought. Each level describes the thinking processes used in geometric contexts. Need to read up more to understand more about Van Hiele's theory.
