About IM 6–8 Math

Developing Conceptual Understanding and Procedural Fluency

As each unit progresses, students are systematically introduced to representations, contexts, concepts, language, and notation. As their learning progresses, they make connections between different representations and strategies, consolidating their conceptual understanding, and see and understand more efficient methods of solving problems, supporting the shift toward procedural fluency. The distributed practice problems give students ongoing practice, which also supports developing procedural proficiency.

Applying Mathematics

Students have opportunities to make connections to real-world contexts throughout the materials. Carefully chosen anchor contexts are used to motivate new mathematical concepts, and students have many opportunities to make connections between contexts and the concepts they are learning.

The Five Practices

Selected activities are structured using Five Practices for Orchestrating Productive Mathematical Discussions (Smith & Stein, 2011).

Task Purposes

Different instructional tasks serve different purposes. Examples include:

  • provide experience with a new context
  • introduce a new concept and associated language
  • introduce a new representation
  • formalize the definition of a term for an idea previously encountered informally
  • identify and resolve common mistakes and misconceptions
  • practice using mathematical language
  • work toward mastery of a concept or procedure
  • provide an opportunity to apply mathematics to a modeling or other application problem


NEW! IM 6–8 Math Accelerated Certified by IM

The IM Accelerated Difference

A Condensed and Comprehensive Two-year Pathway That Addresses all Standards

IM 6–8 Math Accelerated, a compressed version of IM 6–8 Math, is a thoughtful alternative to conventional accelerated programs because its design eliminates the possibility for unfinished learning as students arrive at Algebra 1. It includes all of the standards in IM 6–8 Math and compacts them into a two-year curriculum meant to be covered during grades 6 and 7. The pace is faster than IM 6–8 Math, but no crucial mathematical concepts are left-out.
