Big Ideas: The surface area of a pentagonal prism can be found be finding the sum of the areas of the faces of a 2D net. In this lesson, students build on their understanding of area to find the surface area of a pentagonal prism. Students are presented with the task of determining how much paint finish Luis needs to paint a toy chest he built. By drawing a 2D net, students can calculate the area of each of the faces and then find the sum of all the faces to determine surface area. Vocabulary: area, surface area, pentagon, triangle, net, two-dimensional (2D), three-dimensional (3D) Special Materials: None
