Fraction Fever

Fraction Fever is one of a line of educational games that Spinnaker Software did for multiple machines, and was sold through Radio Shack/Tandy. This particular one is for kids to learn fractions, by hopping on pogo stick to the left or the right, to match the fraction (shown at the top of the above right screenshot). If you zap the right fraction, you get to go to a higher floor, and the fractions get harder.
