For more than twenty years, Marco Ramirez and Chris Confer have worked with administrators and teachers at dozens of schools around the country to cultivate an environment that elevates math instruction schoolwide. Now you can watch as they teach and comment on lessons using these essential math tools—tools that will help you deepen and improve your own math instruction, no matter what grade level you teach.

Anchor Charts describe the essence of a lesson; they help teachers to focus on—and students to remember—the most important mathematical concepts and skills being taught. Anchor charts not only compel teachers to be clear about their instruction, they also improve student comprehension. Watch as Chris discusses the purpose of anchor charts with fifth-grade students and as Marco leads a fourth-grade class through a lesson on building and decomposing an array, frequently referring to and updating various anchor charts.
