Polyominoes -

How Many Pentominoes?

So what is the answer to the question? How many different pentominoes are there? You did work it out didn't you? It really is an interesting problem to investigate. If you haven't already, draw them and see how many you get (yes, I'm begging). On the next page is a picture of the pentominoes. You will want to compare your drawings with them.

Okay, I'll tell you this much. There are 12. Now see if you can draw all 12.
