IM K–5 Math Design Features
IM K–5 Math supports:
A coherent progression of learning
IM K–12 Math™ is fully aligned to the focus, rigor, and coherence of the standards, and has been given the stamp of approval by EdReports, earning perfect scores in the areas of Focus & Coherence and Rigor & Mathematical Practices. The scope and sequence of units, activities, and representations are designed to help students develop a deep understanding of mathematical concepts, build fluency with procedures, and solve mathematical problems that reflect their lived experiences.
Academic language development
Math vocabulary is developed through the process of actively exploring and learning mathematics. Students make sense of mathematical concepts using informal language before academic terms are introduced. Embedded within the curriculum are Mathematical Language Routines to support academic language development for all learners. These routines also provide opportunities for English Learners to engage in the specialized academic language demands of reading, writing, speaking, listening, conversing, and representing in math.
Culturally responsive pedagogy
Materials are designed to affirm students as they build positive mathematical identities. Units and lessons begin by inviting students to use their prior mathematical knowledge, funds of knowledge, language, and culture to make sense of new mathematical concepts. Activities offer collaborative learning opportunities and instructional routines that center student thinking and encourage students to bring their whole selves to math class. Grades K–5 courses (and coming soon to 6–12 courses) include problem-solving contexts that positively reflect ethnically diverse cultures and support the implementation of culturally relevant and responsive pedagogy.
Teacher learning
Units and lessons include narratives that describe the mathematical work that will unfold, and activities and lessons include a synthesis that assists the teacher with ways to help students incorporate new insights gained into their big-picture understanding. Formative assessments help create clear pathways to address student outcomes. Teacher-facing materials support teachers to develop, refine, and reflect on instructional practices.

With that e-mail, we were off and running in the most exciting race of my professional career. We later agreed to deliver a pilot-ready version of grades 6–8 for the 2016–17 school year, rolling out units just in time as the year progressed, and delivered a final version in the summer of 2017, along with aligned professional learning.

Amanda Gorman recited her poem, “The Hill We Climb,” on Inauguration Day. Her words were not only inspiring, but a piercing call to action. I thought about my work at IM and wondered what a commitment to “all cultures, colors, characters, and conditions of man” meant in my role.

One way is through instructional routines like “Which One Doesn’t Belong” and “Notice and Wonder.” These routines give structure to time and interactions. Within the structure, there are opportunities to have time to think deeply and a predictable way to share and deepen thinking with partners and the whole class.
