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

# Classwork

- Mowing the Lawn (Kyle Pearce)
- Use big whiteboards and have each group member write with different colors
- Write pre-scripted questions for audience members to ask during presentations

- Notes

# Finished Early?

- Circle Recap & Right Triangle Refresh
- Some items taken from Michael Pershan

# 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
