FREE for a limited time – Algebra Touch. The animated lessons in this educational app will help kids learn or review algebraic skills. It uses a touch-based approach – tap the operation signs to simplify, drag digits to rearrange them, and draw lines to eliminate like terms. The app is really simple to use. It will not let kids make a move that does not follow the rules of math. They can keep trying a problem until they figure it out! How cool is that? And, the problems are randomly generated so that kids can practice again and again. It covers the following topics: simplification, like terms, multiply then divide, factors, elimination, equations, distribution, and exponents. This app was made possible with support from the Percepts and Concepts Laboratory of Indiana University and the Cave Lab at the University of Richmond.

 VERY cool!!
