My website is so big that it has 30 subdirectories. Which suggests to me that I should take a month or so to tweet a link to one of those each day. I’ll start tomorrow. For now, here’s the link to the site:

1.
_Algebra: Themes, Tools, Concepts_ is a ground-breaking textbook I co-authored in the 90’s, with powerful lessons for grades 7-12. Free, with supporting materials and commentary:

Seeking Depth in Algebra 2
Bad teaching has given that course a bad rep. Done right, it helps prepare *all* students for more advanced work.
Links to a range of curricular materials:

@geogebra 16.
Lab Gear
By far the best manipulatives for algebra — ask anyone who’s used both the Lab Gear and any other option.
Tons of info:

Mathematics Overview
This 15-unit course outline can serve as a summary of central secondary school topics, and a guide to some of the best materials on my website. The tech bits are outdated, but the ideas are solid.

Tools
There is no single theory that answers all pedagogical questions. Still, a constant in my teaching and curriculum development has been the use of learning tools: electronic, manipulative, and pencil-paper.
