Math Expressions

Math Expressions

With the implementation of the Common Core Learning Standards, the district recently adopted the Math Expressions resources for grades K-5. Math Expressions is a comprehensive, standards-based K-5 mathematics resource that offers a balanced approach to teaching and learning mathematics. Math Expressions uses manipulatives, visual models, conceptual language, and real-world situations to help students build deep mathematical understanding.

What does Math Expressions look like in the classroom?


  • Quick Practice – Involves whole-class responses or individual partner practice and is frequently led by student leaders.
  • Student Leaders – Teachers facilitate students' growth by helping all students take on leadership roles with structured practice activities.
  • Building Concepts – Objects, drawings, conceptual language, and real-world situations strengthen mathematical ideas and understanding.
  • Math Talk – Students explain thinking using drawings that support understandings and promote meanings.
  • Helping Community – A classroom in which everyone is both a teacher and a learner to enhance mathematical understanding, competence, and confidence.

Unit Overviews

Summaries of each unit in Math Expressions.

  K    1   2    3    4    5

Research & Background

Summaries of the research used in writing each unit as well as the mathematical background for the units. These can be a great resource to see how individual units build upon instruction from previous units and prior grade levels.

   K    1     2       3       4     5

Family Letters

At the beginning of each unit and in the middle of longer units, there is a Family Letter that explains the concepts being taught.  These letters can be used as a point of reference when helping students with their homework.

Math Expressions Videos

These videos are provided by the publisher and are intended for teachers as professional development on the routines in Math Expressions and the mathematics to be taught.  From a parent perspective, these videos provide insight on the ways that students are solving problems, what is being taught in the classroom, and how it is being taught.
