The Hands On Equations App Level 1 is available for free today for both iOS and Android platforms. It’s normally $4.99 so if you are in the market for an algebra app or just want to try it out, then download it today.
Hands On Equations is suitable for children that are working at around a 3rd grade level and on up. I have heard that you would still want to buy the verbals problem, but that this app essentially replaces the learning system (ie. the manipulative part of the program).
