It is so wonderful that there are all types of helpful math apps out there for students of all ages. Many people have a distaste for math so maybe kids from this tech savvy generation will enjoy this new, fun way to learn. I also know that students can download a graphing calculator for free on their Smartphones as well, something I would’ve loved to be able to do when I had to buy a $100 calculator when I was in school.
I think you forgot a great one there:
I stumbled upon it looking for a way to help my three kids as a single father who can’t afford a private tutor:
It’s called MATH 42 (https://itunes.apple.com/en/app/math-42/id664457128?mt=8) , and helps them (and me ;)) to understand and solve a math problem step-by-step, by giving suggestions on how to solve it and defining unknown notions.
It also enables me to check up on them and their progress thanks to the integrated test mode.
