Shape Sorter

This weekend, Alli was sick with Croup, as well as some allergies (I think). Anyway, we had a lot of indoor play, so she was pulling out toys from her closet that she hasn't seen in a while. One of the toys she pulled out was a Tupperware Shape Sorter. You know the one - it's a ball where half of it is red and half is blue and you pull it apart to get the yellow shapes out of it, and then you have to put them in the right holes to get them back. You remember? We all had them when we were kids... Anyway, she pulled it out and asked for help. So I pulled the halves apart to get the pieces out, and then we put them back together. I would show her the hole for the shape she grabbed and she would put it in. The next day, she saw it on the floor and asked for help again, so I dumped the shapes for her, but I was putting laundry away so I figured I would help her further when I was done. To my surprise, she had 5 shapes already in the ball by the time I returned to her. And now, one day later and only about 2 additional tries at the toy, she can do them all herself except for the trapezoid and the pie shape. For some reason, she can't figure out how to hold the shape to get it in the hole (maybe because these are the only asymmetrical shapes). I was pretty impressed!
