7th Grade Math vs Algebra Touch

"The French mathematician Jacques S. Hadamard found, in a study of 100 leading mathematicians [including Einstein], that the majority of them were primarily visual in their approach." Scientific American, Sept., 1984, p. 56. In seventh grade math the emphasis is on: (1) ratios & proportions, (2) rational and signed numbers, (3) linear equations, (4) scale drawings, area, surface area and volume, and (6) statistical thinking. Math Galaxy’s Seventh Grade Math covers all of the Common Core math standards for seventh grade as listed below. The concepts are presented in bite-size pieces with an unlimited supply of practice problems, with numbers chosen randomly. Illustrations are used throughout to reinforce the concepts. You are guided through problems step-by-step or can just give final answers. Scores can be emailed to be printed. Doing problems earns you robots for the Labyrinth, a maze search game.

To try Algebra Touch for free, see "Algebra Touch: All Ages". This app works best for people frustrated with algebra. “I’m 48. I’ve wanted to learn Algebra my whole life. Tried all kinds of books, to no avail. Your app works for me. I’m so excited. A whole new world opens up.” - Sally G Algebra Touch is a supplemental learning aid that gives you the power to play with algebra directly… and we make it impossible to make mistakes. Poke around freely. Did it react how you thought it would? No? Well then, time to update your internal model of understanding and try again. That’s how people learn. “Seriously awesome app. I am a professional math and physics instructor for middle schoolers thru college students and adults. Have used your app with a number of my students …. And it was like magic. The visual and kinesthetic approach to “moving math” is so powerful!” * Custom manipulative for each algebra topic * Randomly generated practice problems - as many as you could want! * Challenge mode at the end of each module to really test your understanding * Instructional videos for more in-depth explanations * Create your own problems to tinker and push the limit Algebra Touch is highly visual and interactive, so the best way to see what it’s about is to try it. “With this app, the author has successfully made algebra beautiful. I really wish this app existed when I was studying algebra 25 years ago.” - geekswithjuniors.com Over 1 million downloads worldwide!
