I love doing a lesson on growing patterns at the beginning of third grade because it helps me learn a lot about where kids are in the math understanding and how they think. I started the lesson off by showing them a picture of the first two arrangements in a growing pattern.
I purposely start off by showing just a the first two arrangements because it leaves the problem fairly open and there are several correct answers. Then I ask kids to build the third and fourth arrangements in this growing pattern.
Before you look any farther..... Think about how you would solve this problem.
Now check out some of my students' responses.
