I can describe the characteristics of a polygon using mathematical vocabulary.
I can reason about the area of any polygon by decomposing and rearranging it, and by using what I know about rectangles and triangles.
16
I can explain how it is possible for two polyhedra to have the same surface area but different volumes, or to have different surface areas but the same volume.
I know how one-, two-, and three-dimensional measurements and units are different.
17
I can write and explain the formula for the volume of a cube, including the meaning of the exponent.
When I know the edge length of a cube, I can find the volume and express it using appropriate units.
18
I can write and explain the formula for the surface area of a cube.
When I know the edge length of a cube, I can find its surface area and express it using appropriate units.
19
I can apply what I know about the area of polygons to find the surface area of three-dimensional objects.
I can use surface area to reason about real-world objects.
