Product Description
To be used in conjunction with geoboards (or a virtual geoboard), as well as classroom practice in textbook or a worksheet. This is a simple presentation which shows students that parallelograms are made of triangles, and how we derive the formula for the area of a triangle from this fact.

Used with fifth graders with success! Has an extension activity on the last slide.
