I like using this activity because the answer is there, so if they have the incorrect answer it prompts them to ask me and then I can clear up misconceptions. It is also easy to check because I make them write the answer letter in the last column. This is a great alternative to a worksheet! I have a small room and 32 freshman had enough room to complete the activity.
