About IM K–5 Math beta

Creating a Coherent Mathematical Journey for All Students From the Start

Combining the power of standards alignment, problem-based learning, and research-based pedagogy

The IM K–5 Math beta curriculum is designed and organized based on researched principles and learning trajectories, as well as our experience with how teachers use materials, to provide teachers the tools they need to promote student success. The IM K–5 Math beta curriculum supports mathematics teaching and learning with coherently sequenced materials based on the standards and researched learning trajectories.

There are three overarching and interconnected principles—learning, teaching, and equity—that are foundational to everything we create, and guide our understanding of mathematics teaching and learning and who can and should learn mathematics. These overarching principles inform our more specific design principles to support student and teacher learning and usability.

The upcoming IM K–5 Math beta curriculum will be distributed exclusively by our IM Certified™ Distribution Partners.

Purposeful Design of Units, Lessons, and Activities
Every activity and lesson tells a coherent mathematical story across units and grade levels based on both the standards and research-based learning trajectories. This coherence allows students the opportunity to view mathematics as a connected set of ideas and offers them access into the mathematics when developed into the overarching design structure of the curriculum.

Intentional Representations
Mathematical representations are productive tools by which students develop understanding of, and communicate mathematical ideas. The representations used in the K–5 curriculum, and the grade levels at which they are used, are determined by their usefulness for particular mathematical learning goals, making essential mathematical features and relationships salient while suppressing details that are not relevant to the mathematical ideas at that time.

Intentional Use of Instructional Routines
Instructional routines in the materials give structure to time and interactions, allowing students to focus specifically on the mathematics. Throughout the curriculum, routines are purposefully introduced to build a collective understanding of their structure and are selected for activities based on their alignment to the unit, lesson, or activity learning goals.

Contexts Before Formality
To develop a depth of mathematical understanding, students should encounter plenty of examples of a mathematical idea in various real-world and mathematical contexts before that idea is named and studied as an object in its own right.

Balancing Aspects of Rigor
The materials are designed to balance students’ development in all three aspects of rigor as driven by the standards themselves: conceptual understanding, procedural fluency, and application.

Stay updated on the development of the elementary curriculum, and learn  about opportunities to participate in pilots as the team tests new material.
