Teaching and learning math can be hard. Math in Practice is like a math coach for every teacher. This gradebygrade resource is filled with strategies and support for teaching math more confidently and effectively.

Overview
Math in Practice is a standardbased, professional learning resource from Sue O'Connell and colleagues. This gradebygrade K–5 resource fits with any math curriculum you are using. It identifies the big ideas of math content and bestpractice teaching, unpacking essential teaching strategies and detailing why those strategies are powerful.
Math in Practice is not another curriculum; it’s professional development in a book! It supports teachers, administrators, and entire school communities as they:
Guide students into deeper math understanding
Respond to the challenges of their math curriculum
Support students who are struggling, excelling, and anywhere in between 
GradeLevel Books
Each gradelevel book is organized into modules that carefully unpack the specific math content taught at each grade, K–5. Rather than being used in order, teachers can select modules as needed based on their curriculum map, areas of instructional focus, or reteaching needs.
Every module provides:
 insights about the key math ideas
 teacher notes highlighting approaches for promoting student understanding
 a wealth of classroom tasks and activities illustrating the specific strategies
 an extensive collection of corresponding online resources
