Algebra Touch - iPad App Review

A thumbs up!  This app gives a kinesthetic approach to learning algebra.  It starts simple and moves towards the more complex.  Students can manipulate the problems in a low risk activity.  In the middle of the lesson, if the student feels they need more practice , there is a practice button that pops up questions like the ones they were just having difficulty with.

To restart, tap the i in the lower right corner.  Hit the Reset Progress.  So obviously there is only one lesson.  The concepts covered in my short explanation were:
Like Terms, Order of Operations, Factoring

Here's what the website says...
"Drag to rearrange, tap to simplify, and draw lines to eliminate identical terms. 

Distribute by sliding terms across the sum, and Factor them back out by dragging them together.

Easily switch between lessons and randomly-generated practice problems.

Create your own problems or edit current ones.

Current material covers:
Simplification, Like Terms, Commutativity, Order of Operations, Factorization, Prime Numbers, Elimination, Isolation, Variables, Basic Equations, Distribution, Factoring Out, and 'More Advanced' mode."
