Assistant superintendent

We are pleased to offer the following information for LAUSD educators and principals as you consider participating in the IM K–5 Math™ beta pilot for the 2020–2021 school year. If you have questions, please submit them here

Learn more about IM K–5 Math beta from the authors:


With IM K–5 Math beta:

  • students use mathematics to make connections and develop conceptual understanding
  • students enjoy mathematics while they discuss and defend their reasoning
  • teachers facilitate lessons with confidence 
  • teachers and coaches provide feedback to the IM authors to help with future IM K–5 Math and professional learning iterations

"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."

−Tabitha E. 3rd grade teacher Missouri

Sample Teacher Materials for K–5 Units

Teachers are supported with a lesson preview page, side-by-side lesson plan view of student activities and teacher directions, clear guidance for facilitating warm-ups, activities, student discussions, activity and lesson syntheses, and the cool down activity.

Samples do not include the following additions that will be in the beta version of the materials:
  • supports for English learners
  • supports for students with disabilities
  • practice problem sets
  • extension problems
  • section checkpoint assessments
  • guidance for students who need next-day support based on cool-down responses
  • guidance for students who need prior grade level support based on cool-down responses
  • parent support materials
  • streamlined approach to centers across grade levels
  • improved lesson plan format


Scope and Sequence

In IM K–5 Math each grade is made up of eight carefully sequenced and standards-aligned units designed to tell a coherent mathematical story. The attached sequence is from the alpha pilot and may be adjusted slightly in the beta pilot based on teacher feedback.


Sample Lesson Plan

A redesigned lesson plan structure for the elementary classroom gives teachers the support and information they need at their fingertips.


Center Overview

Introducing math center “stages” that give teachers options of activities to address different student knowledge within the same center. Staged centers are carefully designed to progress as units and learning trajectories progress.


Frequently Asked Questions

Answers to the questions we have received about IM K–5 Math beta.


“Students are participating in the IM K–5 Math lessons in amazing ways. Students who used to defer to others are now talking! Students who once monopolized classroom air time are now listening! We are thrilled with the joyful exchange of ideas that happens during these lessons, which is in no small part thanks to the thoughtful design structure.”

Jenna L., Math Specialist, MA

“We chose to pilot IM K–5 Math so we could engage students in a curriculum that prepare students to move toward modelling in mathematics and focus on problem solving and conceptual understanding rather than computation and memorization.”

Ashley G., Assistant Superintendent, DE

“At a recent professional learning for teachers participating in pilot, a teacher summed it up perfectly, ‘IM is really creating what they say they stand for, and you can see it throughout’ which hasn’t always been the case with other resources we have reviewed.”

Kathleen H., K–8 Mathematics Coordinator, MA
