‘Hands-On Equations’ is actually an off-line program that simplifies the process of learning and mastering algebraic concepts. It is both visual and kinesthetic in nature.
The iPad version presents six lessons. Each consists of a video introduction followed by two practice problems and ten exercises. The practice problems and exercises remain locked until students complete each preceding one. Feedback (correct/incorrect) is given after each problem. Students are required to redo incorrect problems.
Although I do not have experience with the off-line program, I am impressed with the iPad version. Use it to introduce algebra to mid-elementary students or to practice algebra with older students.
You can also try the free Lite version before committing to the full version. It allows students full access to the first 3 lessons!
