Use this fun filled three minute activity as a reward for class or individual competitions. Instead of just awarding, for example, 25 extra credit points add some excitement by giving your students a chance to earn a much larger amount or possibly less. You set the 16 possible amounts that are then hidden in balloons. Your student picks one of the clownï¿½s balloons and then she has a choice of keeping it or taking a balloon with a known amount that is offered by the clown. Once all but two balloons are popped she can keep hers or take the final offer. This program has written in Excel 2000. I use Bonus Bucks (offered separately) as the reward in my high school science class but anything from extra credit points to M&Mï¿½s will work. This version includes a license for use in one classroom.
