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.
