一个数学家的叹息

This American Math educator proposes teaching Primary/Sec math in new ways :

  1. HISTORY : how human discovered the math ideas
  2. Do not separately teach Geometry & arithmetics: eg.
    1+3+5+7 =16=4^2
  3. Have fun of Math thru discovery by students, not by remember formula.
  4. Intuition 直觉 : use more
