Area of Composite Figures

50 Minute Class, Curriculum, Geometry

 

Learning Goal: Introduce composite figures with an estimation challenge and develop understanding of how to calculate the area of regular polygons.


Classwork

 Standards:

  • Common Core
    • 6.G.A.1 – Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
  • TEKS
    • G.11(A) – apply the formula for the area of regular polygons to solve problems using appropriate units of measure
    • G.11(B) – determine the area of composite two-dimensional figures comprised of a combination of triangles, parallelograms, trapezoids, kites, regular polygons, or sectors of circles to solve problems using appropriate units of measure
