Sorting is hard

Yesterday Rachel pulled out her shape sorter. The poor girl just doesn't quite grasp the concept of shape sorting, although she is rather good at colour sorting.

She flipped the cube over so that a green side was facing up and then she separated out all the green pieces and proceeded to try to shove them in. The problem is that the shapes and the colours don't match up...

Here she is trying to shove a green square in the hexagon hole. See how she has a green circle ready to put in next?

And this is the face I got when she realized that the square just wasn't going to fit in that hexagon hole:


Sorry, baby! It just isn't going to work no matter how hard you push!
