See why educators love IM K–5 Math.

This curriculum has taken all of the fantastic instructional routines teachers were pulling from multiple sources and tied them up with a great big bow into a rigorous, coherent curriculum resource! Students are talking about math like they never have before, and students who would typically not speak up in math class now join the conversation.

Catherine Castillo, Elementary Numeracy Coordinator for Springfield Public Schools, MO

As a teacher of 25 years, I always worked on creating a strong class community. I had never considered nor had the tools to develop a safe, supportive, inclusive mathematical community until I used IM K–5  in the alpha and beta pilots. IM K–5 changed my math instruction and changed the way my students see themselves. They see themselves as mathematicians who are enjoying doing and talking about math. 

Maureen O’Connell, Math Specialist, Ipswich Public Schools, MA

Here’s what students from a grade 4 class at Wanda Gray Elementary said:

“The fractions are so much fun.”

“My favorite part of math this year is everything.”

“I like working with a partner.”

“I like figuring out what mistake the students in the book made (error analysis).”

“Working with a partner helps me get to know them better and we understand more when we work together.”

Students at Wanda Gray Elementary, Springfield, MO

With IM K–5 every single student can access grade-level math. Students don’t get pulled out for math anymore. They get to be part of the classroom because the curriculum is designed to invite all learners into the lesson with multiple opportunities to use manipulatives, have conversations, share their thinking, and explore the mathematics. It is the most inviting, rigorous, and exciting curriculum I’ve ever taught and it’s amazing how much students can learn and feel successful in math.

Nancy Sirois, K–5 Math Coach, Gerald E. Talbot Community School in Portland, ME

What makes IM K–5 unique for teachers is that it is an educative curriculum. Teachers are learning so much right along with their students. There are so many layers to it. . . community and equity, mathematical understandings, the Five Practices, language routines, and more. I feel like there are years worth of professional learning and development built right into what is presented, and we can put it into practice as we learn together. It’s amazing.

IM K–5 Math v. 360 DESIGN FEATURES

A coherent progression of learning

IM v.360 is fully aligned to the Common Core State Standards and provides the proper focus, rigor, and coherence required to achieve grade-level mathematics. Courses, units, lessons, activities, and representations are sequenced to help students develop an understanding of mathematical concepts, build fluency with procedures, and solve mathematical problems that reflect their lived experiences. Each unit and lesson is designed to build on what students previously learned and is part of a mathematical story that spans units and grade levels. This coherence allows students to view mathematics as a connected set of ideas. 

Academic language development

Students acquire mathematical language by actively exploring and learning mathematics. Tasks encourage students to use informal language while making sense of concepts, and introduce academic language as they strengthen their mathematical understanding. The curriculum provides opportunities to develop mathematical language through social interaction and collaboration, and through the use of math language routines (MLRs). 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

Culturally responsive pedagogy supports students in building positive mathematical identities by providing mirrors to reflect their own cultures and experiences, and windows to see the cultures and experiences of others. Problem-solving contexts that positively reflect diverse cultures are applied to courses in grades K–5 to encourage an inclusive mathematics community and build upon students’ prior knowledge of mathematics, language, and culture. Throughout the curriculum, students engage in collaborative learning opportunities that center student thinking and allow students to participate authentically.

Embedded teacher supports

Each unit, section, and lesson begins with a narrative to describe the mathematical work that will unfold, how it connects to what students have previously learned, and how it will prepare students for future coursework. Lessons and activities end with a synthesis that supports teachers in clearing up any misconceptions or questions students may have encountered during their learning. Throughout lessons and activities, teachers can find guidance on providing more access with embedded language support, UDL guidelines, and enrichment opportunities for students who need them. Finally, teachers are invited to develop and refine their practice with reflection questions centered around math content, student thinking, pedagogy, and access and equity.

IM K–5 Math MeetsExpectationsin All EdReports Gateways

IM Certified® math curricula have earned EdReports’ highest ratings across all three review gateways: focus and coherence; rigor and mathematical practices; and usability. EdReports is a highly regarded independent nonprofit that reviews K–12 curricula for standards alignment and quality.
