For this lesson, I give each kid a small cup of Cookie Crisp cereal, a dry erase board, and an expo marker. I then read aloud the book The Doorbell Rang by Pat Hutchins.
The kids love this amazing activity, and it is a great way to explain the concept of division with a real-life connection. Everyone can relate to sharing something with friends! After finishing the book, I have the kids take different numbers of cookies out to help solve other simple division problems. It's also easy to make the connection back to multiplication at this point by skip counting each group of cookies to get back to the total.
Oh the best part? Afterwards you will likely have half a box of Cookie Crisp in your supply closet to help fight your after school munchies... ;)
