Week 3

Finding Area of Parallelograms by Decomposing and Rearranging

Learning Goals
  • Calculate the area of a region by decomposing it and rearranging the pieces, and explain (orally and in writing) the solution method.
  • Recognize and explain (orally) that if two figures can be placed one on top one other so that they match up exactly, they must have the same area.
  • Show that area is additive by composing polygons with a given area.
