For my 7th graders, surface area usually is one of the hardest topics we do all year. I work with a lot of students who don’t have a solid foundation with math and especially with spatial ideas. When they take the final test on surface area they have to really be able to conceptualize a three-dimensional idea in a two-dimensional drawing. To get them there, students need to see surface area in the 3-D realm and then we need to help them transfer everything to paper. I find that they just need a lot of practice and a clear transition from the real life learning to the drawings. The eleven activities in this post will help your students get that practice they need with surface area, in both the 2D and 3D worlds.

Surface area can be a very tricky concept for 7th grade minds. It has a lot of moving parts in it and sometimes it is just too much for these little balls of craziness. I feel like with this topic you really have to go back to finding area, and then work your way through a forest of prerequisite skills. At the end of the tunnel you will come out with them having an understanding of what they are doing. Also, with this topic in particular I think there are many ways to get it and each students should use the way that works with them. Therefore, in this post I will show you how I chunk the learning for surface area through I can statements.
