Redefining Math Education for the Next Generation

Welcome to IM® 360, the new version of the IM K–12 Math curriculum. After listening to valuable feedback from educators and students alike, we’ve made transformative changes to create a more inclusive learning environment. IM 360 empowers teachers to ensure that every child learns grade-level mathematics and develops a positive mathematical identity through engaging learning experiences that shape their understanding and personal development.

About IM 360

IM 360 is Illustrative Mathematics’ most extensive upgrade to date for our K–12 math curriculum. Our innovative approach to problem-based instruction empowers teachers to ensure that every child learns grade-level mathematics and develops a positive mathematical identity through engaging, motivative learning experiences.

Why Now?

Since 2011, school leaders, teachers, and students have provided us with feedback on the curriculum, and we listened. We implemented updates and revisions across the IM curriculum in response to the needs of teachers and students.

What’s New?

IM 360 contains upgrades, enhancements, and revisions to our K–12 curriculum that were made in response to the needs of teachers, school leaders, and students. See our FAQs below for a more detailed list of what’s new.

How Will It Affect You?

Whether you are new to the curriculum or have been using IM for years, a version of IM 360 will be available to schools and districts at illustrativemathematics.org for free, and from our IM Certified® Partners Kendall Hunt and Imagine Learning.


Grade 1, Unit 2

Grade 1, Unit 2 includes more direct guidance for completing word problems with early readers. The number of equations was reduced, thereby placing the focus more on developing problem-solving skills and making sense of word problems. The advancing student thinking field is updated with more specific supports and guidance for teachers, which are beneficial in promoting students’ critical thinking and analytical abilities. These changes are meant to create a more effective learning experience for first-grade students.

Grade 4, Unit 2

Grade 4, Unit 2 further builds fraction understanding using familiar representations. Teachers will find the updated advancing student thinking beneficial because additional supports have been included to assist in promoting students’ critical thinking and analytical abilities.  Teachers will have more guidance and resources to address students’ questions and challenges in real-time. The just-in-time support provided through these updates will help teachers intervene effectively and address students’ needs more efficiently, which ultimately contributes to a more supportive learning environment in the classroom.

Sections A and B highlights

  • Embedded Math Community pieces. Contained in the first two units of each course are eight exercises designed to support teachers as they start off the school year establishing norms and building a math community. Ongoing work is woven into later units inviting communities to revisit and revise norms, and look for time where the norms are supporting the community.
    • Lessons 1, 3, 6
  • Embedded Math Language Routines. The first instance of each Math Language Routine in a course is embedded and includes additional language to support teachers implementing the routine with students for the first time. Select Math Language Routines have been embedded throughout the lessons to support the math language development of all students, and especially English Learners.

    • Page 81 Co-Craft Questions
    • Note: This type of embedding brings 6–8 curricula into closer alignment with IM K–5 Math.
  • Which Three Go Together? The instructional routine Which One Doesn’t Belong? Has been reimagined as Which Three Go Together?
    • Page 95 Lesson 4 Activity 1
    • Page 111 Lesson 5 Activity 1
  • Number Talks and Algebra Talks are now Math Talks. For this version, Number Talks and Algebra Talks have been brought together under the name Math Talk, bringing greater alignment to IM 6–12 curricula. All Math Talks have a consistent four items for teachers to reveal one at a time with their students.
    • Page 76 Lesson 3 Activity 1
  • 5 Practices. The standard language for all 5 Practices-tagged activities has been revised and clarified to better support teachers implementing this routine.

  • Revised Contexts.
    • Page 65 Lesson 2 Act 3 revised to use the basic recipe for Coco bread, a popular Jamaican food.
    • Page 128 Lesson 6 Activity 2 is still reasoning about quantities and prices, but now in a context of bottle returns instead of concert ticket sales.

Grade 8, Unit 3

Grade 8, Unit 3

  • Materials and Preparation. The start of each Teacher Guide includes a chart laying out needed materials and blackline masters by activity number.
    Added clarity around Materials to Gather, Materials to Copy, and Required Preparation at the lesson level so teachers have one place to look as they prepare for a lesson.
  • Section Narratives and Goals. New section narratives and section goals are included for each section in a unit. These offer teachers a high level overview of the work in a section along with a key image to help orient teachers to the section.
  • Teacher Reflection Questions. Included with the section narratives is a set of three Teacher Reflection Questions. These questions invite teachers to dive into the mathematics in the section, reflect their teaching practice, and consider how classroom structures and instructional decisions impact students’ beliefs about their own and each others’ mathematical capabilities.
  • Section Checkpoints. Sections have 1–3 Checkpoint items that align with the goals of the section. These short formative assessments also include guidance, titled Responding to Student Thinking, to support teacher planning based on student responses.
  • Math Language Routine 7 Compare and Connect. In activities where we want students to compare representations or strategies and make connections, we’ve embedded the Math Language Routine Compare and Connect. Given the close relationship between this routine and 5 Practices, we’ve used similar standard language across activities tagged with this routine.
