In this SmartBoard activity, each page has a group of fractions scattered randomly around a shape. Students must find the fractions that meet the criteria stated in the shape. After they have studied the page for 1 minute, they touch the fuse of the firecracker. They then touch as many fractions as they can that meet the criteria. If they are correct, a clown appears. Incorrect answers are marked with a "boom". The firecracker will go off in 30 seconds. Criteria listed include: equivalent to one-half,less than half, more than half, improper fractions, simplified, and add up to one whole.
