I love to integrate literature with math when possible, so I began the lesson by reading aloud the picture book Lunch with Cat and Dog. Even though the book was a little babyish for them, they loved it! It's is a silly story that introduces students to the importance of equal portions, and it's a quick read. After that, I posed a similar fraction word problem for them to discuss.
