Clicker questions coming

My advice:

1. Take out some notebook paper.

2. I will fill in the blanks on the board. Copy info down. 3. Write your guess someplace off to the side so you

can cover up your answer when you study your notes

4. Write the correct answer in another place you can cover up, NOT immediately next to your first guess. 5. This will make it hard for you to peek at the right

answer when studying your notes
