1. Review Game! Please - Turn in your homework and have a seat!
REMINDERS:
Your test is TOMORROW.
Blue books – due tomorrow!
Your lab report is due MONDAY.

2. Your Groups: 10A

3. Your Groups: 10B

4. ZONK RULES:
For each round, your team will collaborate to answer the question I ask on your white board.
If your team gets the answer CORRECT – one person on your team will choose a random slip of paper with a number on it. This number will be how many points your team wins.
If you pull a “ZONK” – your team loses HALF of their points.
Your team spokesperson will give the final answer.
Ready… set… GO!
