“Almost all parents think that it is a good thing for their kids to do something called “learning math” and are therefore in the market for software that will “teach kids math.” So far, so good. But what is not so good is that their ideas about what math is, and why the kids should learn it, are so flimsy that they are in a similar position to people who want to buy food for their kids but do not know the difference between nutritious food and junk food.
In my view 99% of what is sold is junk math.”
