The IM Certified Difference 

  • Problem-based with real-world connections: Students discover, understand, and internalize key math concepts and apply their learning to various real-world problems and scenarios, simultaneously building procedural fluency and conceptual understanding.
  • Diverse representations: With images and scenarios that reflect a diverse society, students can see themselves and their experiences represented in the problems they’re solving, creating more meaningful connections with new concepts.
  • Grounded in best practices for effective mathematics education: IM’s rigorous, standards-aligned K-12 curricula are expert-authored and rooted in well-respected pedagogy and methodology, meeting all expectations for focus, coherence, rigor, mathematical practices, and usability, according to EdReports
  • Full-service experience: Professional learning led by IM Certified® facilitators and an active online community give educators the support needed at every level to create effective classrooms and ensure all students are given equity and access to grade-level mathematics.

My students’ mathematical thinking blows my mind! Each and every student in my classroom can explain their answer. Their strategies look different because they all approach and solve problems in different ways, but they can use words, diagrams, and equations to explain their answer.

The curriculum facilitates productive struggle for our learners, and teachers have been excited to shift their instruction from being the ‘sage on the stage’ to the ‘guide on the side.’

IM 9–12 Math has spurred a rapid 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.
