Every elementary or middle school math teacher needs this powerful math visual aide hooked up to his or her projector. It quietly connects the movement of your finger(s) on the screen with mathematical relationships. Swipe left or right on a numerator to see a pie chart change. Do an outward pinch to change the number of slices in the pie, or an inward pinch to reduce the fraction. There are four options on the main menu: Fractions, Integers, Decimals and Multiply. In each case the sets or graphs change every time you touch the screen. This app could be used as a standalone activity or with written exercises. The main content is targeted at 4-8 year olds but it could be useful for upper grades as well.
