*Math in Practice* is a comprehensive, grade-by-grade professional learning resource designed to fit with any math curriculum you are using. It identifies the big ideas of both math content and math teaching, unpacking key instructional strategies and detailing why those strategies are so powerful.

Rather than providing another sequence of lessons and units to take students from the beginning to the end of the year, *Math in Practice* focuses on developing deep content knowledge, understanding why certain strategies and approaches are most effective, and rethinking our beliefs about what math teaching should be.
