Clicker questions coming l.jpg
Clicker questions coming tomorrow?

My advice:

  • Take out some notebook paper.

  • I will fill in the blanks on the board. Copy info down.

  • Write your guess someplace off to the side so you can cover up your answer when you study your notes

  • Write the correct answer in another place you can cover up, NOT immediately next to your first guess.

  • This will make it hard for you to peek at the right answer when studying your notes
