Algebra Lab Gear books

Errata

Henri Picciotto

The Lab Gear books I wrote for Didax are the best books on how to use algebra manipulatives to teach a wide range of topics. (Where to get the books.) Unfortunately, they contain some errors, many of them minor. As I create corrected versions of those pages, I will post them here. If you find more errors, let me know!

Algebra Lab Gear: Basic Algebra

Algebra Lab Gear: Algebra 1
