Deriving the Area of Geometric Figures (Plastic)
This package includes all the pieces necessary, for hands on discovery, of how to derive the area formulas for the following figures: Rectangle Parallelogram Triangles Rhombus Kite Irregular quadrilateral Polygon and Circles and Parts of a Circle Help your students understand how to make associations and cultivate deductive thinking. Go beyond simply memorizing the formula. The skills they develop using this curriculum will prove beneficial further on down the road when they will be faced with geometric proofs, and derivations. Constructed with precision, these cards will eliminate the need for you to spend time constructing area figures.
