Students have been learning about solid shapes and have been determining their surface areas. First, students looked at the different types of solids and determined what shapes made up their surfaces. Next, students looked at the nets of three dimensional shapes. They used what they knew about the shapes that made up the surfaces of the solids to draw a these two dimensional representations of them. To further investigate nets, students traced Rubik's Cubes, flipping from one side to another and keeping track of which sides they had traced. They then cut out the resulting net they had created and folded it into a cube. Students then looked at surface area by finding the dimensions of various solids and determining the areas of each of their sides. They found the surface area of rectangular prisms, triangular prisms, trapezoidal prisms, cylinders, square pyramids, triangular pyramids, and cones.
