Today I found this great app called Algebra Touch. Now I’m no math teacher, so take my critique with a grain of salt, butI thought it was engaging and I was able to practice algebraic thinking without having to do the computational part. It has been a very long time since I have had to any real math and this app allowed me to manipulate the problems and quickly solve them.
