# Zero and negative exponents

Lesson 2 of 10

## Objective: SWBAT explore zero and negative exponents.

## Big Idea: Use logic to prove the rules of zero and negative exponents. These rules are not made up - they make mathematical sense!

#### Warm Up

*10 min*

Each day, students complete a warm-up 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.

#### Huddle

*10 min*

In this lesson, I like to close the lesson by asking two kids to come up to the board and prove that:

1) anything to the zero power is 1; and

2) the properties of negative exponents.

The first one is generally much easier than the second; the second one requires quite a bit of guidance, but it is pretty powerful to get kids to do this. I try to do this over the course of a few days to ensure spiraled review.

#### Homework

*15 min*

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