We've been doing some butterfly work too. Here is a gluing collage we made of some butterfly wings, and also using scarves as butterfly wings to do some flying of our own.
We also did Muffin Tin Monday for lunch, choosing all foods that the caterpillar ate in the book. They were practically incoherent with glee to get a tiny piece of cone and bite of ice cream as part of their lunch. :) No seconds on that part though, just the healthy stuff.
Mint chocolate chip is my favorite!!
