McGraw Hill (coming soon)

I have used the IM Algebra I curriculum this year. It has been such a rewarding and amazing experience for my students—I feel like they have progressed so much more in their mathematical understanding. The quality of my instruction and the quality of intervention in my immersion class have improved so much, and it is entirely due to the thoughtfulness and the quality of your curriculum.

— Jim Dougherty, Mathematics Teacher, Cincinnati, OH

The curriculum does a fantastic job of spiraling previous content into current units, which means I do not have to find other ways to incorporate the ideas—IM does it for me! This curriculum allows students to dig deep in to math in a fun and practical way and I get to be a guide that cheers them on!

— Caitlin Craft, Math Teacher, Albuquerque Public Schools, New Mexico

IM 9-12 Math has spurred a rapid paradigm shift in how I go about teaching and learning mathematics. Furthermore, my students have developed a deeper understanding of mathematical concepts through making meaning of their conversations with each other and myself about the topic at hand.

— Joseph Dziuba, Math Teacher, New Brunswick Public Schools, New Jersey

A High School Curriculum That Tells a Story

Teacher-tested, standards-aligned, and research-based

Designed for high school learners, this curriculum encourages the problem-solving skills students need to better understand the real world. The story of each course is told in units; each unit has a narrative that describes the mathematical work that will unfold in that unit. Each lesson in the unit also has a narrative.

IM 9–12 Math meets expectations in all EdReports Gateways. EdReports is an independent nonprofit that reviews K–12 instructional materials for focus, coherence, and rigor. Read the full analyses for Kendall Hunt and LearnZillion.

IM Certified Professional Learning

IM Professional Learning for mathematics is deeply integrated with the curriculum. The program provides teachers and leaders long-term, sustainable support for developing, refining, and reflecting on instructional practices.
