Algebra: Themes, Tools, Concepts
by Anita Wah and Henri Picciotto
to Sample Lessons
Algebra: Themes, Tools, Concepts (ATTC) is an algebra textbook I co-authored in the early 90's. It was ground-breaking in some ways, and includes many extraordinarily effective approaches to the teaching of algebra. In fact, ATTC features powerful lessons on many parts of secondary school math, which are used by teachers in grades 7 to 12.
On the other hand, ATTC is not particularly easy to use as a textbook, and never became a best-seller. Thus, the publisher decided to declare it out of print, and the copyright reverted to the authors. It is now available absolutely free, right here, for your non-commercial use.
