Think of this as The Global Math Department for education. It is a community of math teachers on the Internet. They communicate via Twitter and blogs so they use the nickname Math Twitter Blogosphere (MTBoS). First and foremost it’s a support group for teachers in year 0 to 50 (preservice to retired!). Amazing resource for teachers who want to learn math as well as teach it.

Thinking Blocks is an interactive tool that helps students model math word problems. Ideal for Grades 1 through 6. Students learn how to create TAPE DIAGRAMS to solve word problems. This resource is a must for every teacher.

It is critical that we take a moment to review the emerging evidence on the impact of timed testing and the ways in which it transforms children’s brains, leading to an inevitable path of math anxiety and low math achievement.
