I came across this website recently http://algebramind.com But I have not used it.
I have watched the introductory video on the home page of this site and was very disappointed (the video: every child is a genius). The concept is good, the pictoral representation to teach algebra is a basic concept that should be good, but if their program is anything like their introductory video then I would advise no one to buy the product as there are serious basic mathematical errors in the video - some as basic as drawing the wrong number of elements and some slightly less obvious of switching where a symbol is used so that it means an entirely different thing. Unless they clean up their program one might be better teaching this without the program.
