## Huddle

10 minutes

In this lesson, I like to review the silver problem (see 6 - 1 huddle image).  Not only do I ask for the correct answers, I ask students to say what was most likely to be popular wrong answers.  By doing this, I try to highlight key misconceptions so students deepen their understanding.

The silver and gold problems are from Holt Algebra I.

## Homework

15 minutes

Homework 6 - 1 HW79 Laws of exponents is to be completed at home and should take students approximately 15 minutes.
