## Math Myths

Don Cohen, AKA The Mathman, has been helping children of all ages to learn Math for 34 years. He has a CDROM book, Calculus By and For Young People, which he sells via his site.

I found these "Math Myths" from his site to be quite interesting:

1. You can't take 7 from 3.
2. When you multiply, the answer is bigger.
3. You have to add from right to left.
4. When you subtract the result is smaller.
5. Fractions are small numbers.
6. There's only one way to do something.
7. When you add the result is bigger.
8. When you divide the result is smaller.
9. I can't do it unless someone tells me how to do it.
10. Math is hard and only a few people can do it.
11. You have to know everything about whole numbers before you can do fractions.
12. You have to know algebra before you can learn about calculus.

How many of these "facts" do we take for granted, even though they're not true?

## Dismantling the calculus pyramid

Here's a quick 3 minute TED video by Mathemagician Arthur Benjamin. The topic: Benjamin's idea about how to change Math education. He makes the point that Math education is like a pyramid with all classes (e.g. algebra, geometry, trigonometry) building up to calculus. But, he argues, calculus is not very useful to many of us in our ordinary lives. So, what should the pinnacle of the Math pyramid be? Watch the video and leave your comments.
