"The Very Hungry Caterpillar" is our book for the next 2 weeks. Building off from that we'll learn about caterpillars and butterflies. We got the caterpillars from insect lore and they are loving watching them as they grow!
We'll also study other bugs, days of the week, healthy foods...so much to learn about in that book!
I don't do letters of the week anymore. Here's one link to back up my reasoning
