The Very Hungry Caterpillar
While reading the book, simply take time to count the different food items. I believe it states how many pieces of food the caterpillar ate on certain days. Just count them with your child. It's good practice and it introduces them to counting a small number of things.
I need to get this book for my kids (I admittedly get tired of reading Green Eggs and Ham, though I fake enthusiasm every time).
