The class is really into figuring out what we will wager for our guesses. Their homework was to write down their guesses. To make it official we had to have them write it on the board and take a picture so we have documentation of their guesses.
The wager is a small something to eat with the class: box of cookies, dried bananas, fruits, bag of chips, gallon of juice, etc. We will be enjoying these items on the day before our winter break. Since the first question will have one winner (closest to the answer) we should have a heft amount of goodies to enjoy. They are on a ROLL!
