Quadrilaterals out of the back of a truck

[chrisstone]

A simple idea of match the shapes onto the correct named circle, there are some little extra ideas, when dragging something out from behind something, its not always easy to do, or you grap two at once, so I have put tabs on them to make it easier. The tabs then disappear as their colour is the same as that its placed on.... Simple really
