— By **Paul Lockhart**

In this 140-page essay, Paul Lockhart decries the deplorable state of the traditional U.S. K-12 math educational system, and passionately calls for the need to teach mathematics as a **creative endeavour** and an **artform**.

#### FEATURED THESES

- Mathematics is primarily an
**artform**, not a tool. **U.S. K-12 math education**has lost touch with what mathematics is, and what mathematicians do.- By teaching math without the
**whys**and the**contexts**, mathematics is in effect reduced to an empty shell. - The essence of mathematics is
**abstraction**— not the memorization or applications of facts and figures.

- A thorough treatment on
**mathematical investigation** - A mental framework for dealing with
**intellectual plateaus** - Illustrative, beginner-level
**problems**(with guidance or hints) - An
**integrated approach**to problem solving and the associated mental processes
