Surface Area

Good Evening,
I am looking to create a lesson for 6th grade to meet the following standard. Determine the surface area of triangular and rectangular prisms (including cubes). If you have any lessons or ideas, I would greatly appreciate it. @Aimee_DeFoe @AlainaHaws @Jimmy_Lin @Tina_Dietrich

Good question! I want to brainstorm a bit more about this idea when we get back into the office after VEX Worlds and the Educators Conference.

I think we could probably build on this from a different idea that was shared related to calculating the volume of prisms with fractional edge lengths. Students could also calculate the surface area of that prism they create.

Perfect…

Here’s a possible idea for determining the surface area of rectangular prisms (which you could definitely also use for cubes). As @AlainaHaws suggested, it is inspired by the previous community post about calculating the volume of prisms.

You could build a rectangular prism using the IQ Kit:


There are many ways to build a rectangular prism using the kit, but I used these pieces:

Students could calculate what they believe the surface area of each side will be using the 1/2 inch segments on the pieces, then wrap the prism in paper, measure, and confirm their earlier calculations. That way there is actually a surface involved, rather than the space between IQ pieces on each face, if that makes sense.


Hope this is helpful!
