My co-worker found this activity that you create a caterpillar with a shoebox and feed it random things. I made the foods that the caterpillar can eat. In this version, you can change the foods, shapes, and letters that he ate. Later during the month, I was thinking of changing the foods to numbers and our letter sounds. I will update it soon. Take a look at PDF Feed the Caterpillar for better previews of the file.
