Geostacks

Ruth was excited when I got this game out this evening. Sorting colours was no problem.
Then sorting by shape.

Then finding a shape in a specific colour.

Then putting two bits of information together.

Then to put two shapes on top of each other. She decided to use just one colour for each set but I had to show her that there was only 1 of each, so the squares on the left had to be different colours.
