This goofy old game can help a little with adding fractions. Whole was originally made by Noam Davidovics and Daniel R. Wallace. It is a great game for number play. You can slide any piece directly up, down, left, or right, as long as the total is not greater than 1. The new total will be formed. If it is a whole 1, you get a point. It works best on a larger screen, we are working on getting an updated version made.
