*Learning Goal: Introduce surface area with a 3 Act task. Then, apply the task and understanding of surface area to explore prisms and cylinders.*

# 3 Act Math

# Classwork

- Problems to be placed in unit or spiraling
- Geogebra Resource for Cross Sections (Steve Phelps)
- Warm Up / Task Handout
- Notes

# Standards:

**Common Core**- 7.G.B.6 – Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

**TEKS**- G.11(C) – apply the formulas for the total and lateral surface area of three dimensional figures, including prisms, pyramids, cones, cylinders, spheres,

and composite figures, to solve problems using appropriate units of measure
