Take what your students have learned about arrays and multiplication to create student skyscrapers. Each student can choose to make a skyscraper with 2, 3, or 4 sections. In each of the sections they are tasked with finding the total number of buildings in each section, and then the windows in all.

There is room for differentiation because students can select how many sections they would like to include. I then have students design their building using card stock and various sized stickers as buildings. The buildings lined up make for a beautiful skyline bulletin board!

Part two of the activity requires students to make up word problems about their buildings. You can then use these for other students to solve, or select one student's building and make up word problems for the students (i.e. If every apartment has two dogs, how many dogs are there in all? Assuming that every window is one apartment.)

Use this as a long term project, there is room for differentiation, AND you can create a beautiful bulletin board. My students LOVED this assignment!
