For more than twenty years, Chris Confer and Marco Ramirez have worked with administrators and teachers at dozens of schools around the county 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.

Simple and accessible, Journals bring the Common Core State Standards'' Mathematical Practices to life in the classroom on a daily basis. Math journals invite students to relate their own ideas, experiences, and prior knowledge to the learning at hand while encouraging them to clarify their thoughts and to use challenging and precise math vocabulary. Watch Chris explore with first-grade students the many uses of math journals and, with fifth-grade students, investigate a mathematical argument as they defend, revise, and reject conjectures using math journals.
