**HOMEWORK VIDEOS are a GREAT tool for review!!

Get out:1. A blank piece of notebook paper

2. A pencil3. Put your name and period on the top

4. Title it Review5. Number 1-17

Review DayToday’s Goal: Answer all the review questions correctly (to prepare for

Monday) and figure out the bonus!

• What to do:1. Get a partner2. Start at any question, read it, answer it correctly,

circle the letter it tells you to circle.3. Figure out the bonus after answering all the

questions.4. Turn in your paper when you are done…YES, it is

a grade
