#### Warm Up

*10 min*

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 min*

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.
