The Quadratic Formula
In the period following the publication of Algebra: Themes, Tools, Concepts, we started asking our Math 1 students to write and illustrate a short report or poster, tying in four representations of a trinomial in the form x^2+bx+c. (Math 1 is Urban School's Math Department's version of Algebra 1, sort of.) I just posted a… Continue reading The Quadratic Formula
Playing Games
I attended an Escape from the Textbook! meeting last weekend. The first part of the meeting focused on the mathematics of the game of Set, and the second part launched a conversation about assessment, which will continue in future meetings. Avery Pickford took notes, and posted them on his excellent blog, "Without Geometry, Life Is… Continue reading Playing Games

It may be a useful complement to the abundant notes in the Teachers'… Continue reading Additional notes on ATTC

ATTC upgrade
Algebra: Themes, Tools, Concepts (ATTC) is an algebra textbook I co-authored with Anita Wah 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… Continue reading ATTC upgrade
