Deriving the Area of Geometric Figures

• No Lamination Required.
• Printed on Premium Thick Plastic and Cut.
  
• This material is ready to start using. No other prep work is needed.

This package includes all the pieces necessary, for hands-on discovery, of how to derive the area formulas for the following figures:

1. Rectangle
2. Parallelogram
3. Triangles
4. Rhombus
5. Kite
6. Irregular quadrilateral
7. Polygon and
8. 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 down the road when they are faced with geometric proofs, and derivations.

Constructed with precision, these cards will eliminate the need for you to spend time constructing area figures.
