Teachers of Good Things

Developmental Mathematics is an affordable self-teaching math curriculum, composed of a complete workbook series that progresses through the basic elements of arithmetic into the beginnings of algebra. Each workbook or “level” concentrates on certain topic(s) and there is no spiraling. It can be used both as a full curriculum or as a supplemental aid.

“Its teaching methods cultivate independent thinking through deductive-reasoning and problem solving. Mathematical concepts and computational skills are presented clearly and concisely to allow students to advance independently.”

Prices: Student workbooks (levels) $12 each, teacher guides $3.50 each, a complete set of all 16 levels $220.
