Volume: Spheres

Lesson Prep

Lesson Details

• Duration: 50 minutes

• Learning Goal: Apply what we’ve learned so far to a 3 Act task, and then build understanding of how to calculate the volume of spheres.

Prework

• Consider joining our free online workshop to explore 3 Act Math more in depth

• If possible, use big whiteboards and have each group member write with different colors

• Write pre-scripted questions for audience members to ask during presentations

• Watch the embedded video above to see how we use formative assessment
