Objective

SWBAT understand and apply the formulas for volume of cylinders, cones, and spheres.

Big Idea

Why do the formulas for volume of a cylinder, cone, and sphere make sense? How are they related to the area of a circle?

Warm Up

10 minutes

Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material.  Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

For a video narrative about how I structure each lesson, and how the warm-up fits in watch my Lesson Structure video.

Huddle

10 minutes

For the huddle, I like to review Problem 7, which pushes kids to explain WHY the formulas for teh volume of solids work the way they do.  I find that if they can reason WHY on a particular formula, they will retain it much better.

It's also great practice for kids to explain their reasoning, yet again.

Homework

15 minutes

Homework HW128 is to be completed at home and should take students approximately 15 minutes.
