This addresses one of my questions—how to use the scoreboard for a class that has no homework.
One WBT blog mentioned using stickers given to the winners of a team. These stickers can be used for ‘free’ points on a question on a test. The student puts the sticker by the question on which he or she want free points. I can't find the post, maybe someone will read this and do a better job of explaining.
For myself, I have found free time as an incentive gets out of hand so I don’t like using it at the middle school level. I once took a survey to find out from the students what they wanted as incentives. I stipulated that incentives had to follow school rules. The only one I remember they all liked was the free homework pass.
All this said, I haven’t used WBT but am very excited to give it a try. I cannot wait to see how others respond.
