A Grade-by-Grade Guide for Teachers

Math in Practice, the new resource from Susan O’Connell and colleagues, is a comprehensive, grade-by-grade resource designed to fit with any math program or resource you are using. It is not a curriculum. It identifies the big ideas of both math content and math teaching and shares key instructional strategies—and why those strategies matter. Math in Practice will support teachers, administrators, and entire school communities as they rethink the effective teaching of mathematics in grades K–5.

There is no shortage of math programs and curriculums available. All promise a sequence of units to take students from the beginning to the end of the year—but they’re missing one critical piece: professional development.

Math in Practice bridges this gap with support for these key questions:

  • How do we promote deeper, more thoughtful learning in math?
  • Why should we approach math instruction differently?
  • What resources are needed to do all of this effectively?


Each Grade Level text comes packaged with A Guide for Teachers.

The Guide for Teachers is the linchpin of the entire series. It lays out key instructional ideas and approaches, providing a foundation for the accompanying grade-level books. Throughout the Guide for Teachers, you'll find what standards and research say about these topics, extensive support for effectively incorporating these strategies into your everyday instruction, and opportunities to reflect on your teaching. Explore instructional strategies such as.

  • Asking questions that stimulate student thinking
  • Exploring math concepts through modeling
  • Using formative assessment to guide instruction.


Grade level topic coverage may vary across Provinces in Canada.
