I teach and develop educational software for kids and teachers. I studied Mathematics Education with Robert B. Davis. I am a member of the Etoys Education Committee. Etoys is an free educational tool for teaching children powerful ideas in compelling ways. My main blog is Mr. Steve's Science
I design, develop and write about learning experiences for anyone from babies to researchers. I started several online educational communities, including the Natural Math network and the Math 2.0 Interest Group.
The goal of this course is to aggregate a curated, reviewed collection of interactive multiplication models. Some of the communities and projects involved in this include Natural Math, Etoys, Illuminations, The Mathman, and SubQuan.
