Array City is an idea that floats around on Pinterest. The basic concept is that students create buildings in which the windows are an array. What I did was take this concept and organize it into a student-friendly organizer, to help the project run more independently. I also added an observation component. This was a HUGE bonus - instead of just having a pretty bulletin board, I was able to have a meaningful discussion with my students. My third graders were making observations about prime numbers, square numbers and finding patterns that even I hadn't thought of before!
Another bonus? It is perfect for differentiating because you choose which numbers to assign to which students!
I hope you enjoy this project as much as my students and I do!
