See how learning builds across IM K–5 Math v.360

IM K–5 Math v.360 provides a coherent progression across the elementary grades. Students begin with early number sense, shapes, place value, and addition and subtraction. From there, they move into multiplication, division, fractions, decimals, area, and volume, concepts they continue building on in middle school mathematics.

Kindergarten

Students represent and compare whole numbers, compose and decompose numbers, begin developing their understanding of addition and subtraction, and describe shapes and space.

BUILDS TOWARD

Grade 1 work with operations, place value, measurement, and geometry.

Grade 1

Students build addition and subtraction strategies, work with numbers to 120, explore length measurement, represent data and time, and reason with shapes.

BUILDS TOWARD

Grade 2 work with base-ten understanding, fluency, measurement, and equal groups.

Grade 2

Students deepen their understanding of place value, add and subtract within 1,000, measure length, work with data, time, and money, and begin reasoning about equal groups.

BUILDS TOWARD

Grade 3 work with multiplication, division, area, scaled graphs, and fractions.

Grade 3

Students build their understanding of multiplication and division, arrays and area, and fractions, and learn to reason about data, measurement, and shapes.

BUILDS TOWARD

Grade 4 work with multi-digit operations, fraction equivalence, and geometry.

Grade 4

Students build fluency with multi-digit multiplication, develop multi-digit division, deepen work with place value and fractions, and analyze measurement and geometric figures.

BUILDS TOWARD

Grade 5 work with volume, decimal operations, fraction operations, and multi-digit multiplication and division.

Grade 5

Students work with place value, volume, decimal operations, fraction operations, multi-digit multiplication and division, coordinate grids, and properties of shapes.

BUILDS TOWARD

Middle school work with ratios, expressions, equations, geometry, and data.

With IM K–5 Math, 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.

What makes IM Math different

In an IM classroom, learning starts with a meaningful problem. Students compare strategies, and teachers guide a synthesis that makes the key ideas explicit.

Coherent by design

Ideas build across lessons, units, grades, and courses. Curriculum, professional learning, and IM Certified partners all reinforce the same instructional model.

Grounded in decades of research

Built on research into how students learn mathematics, with embedded supports for English learners and students with disabilities.

Written by a lead writer of the standards

Created by mathematicians and educators, including Dr. Bill McCallum, a lead writer of the Common Core State Standards for Mathematics.

Designed for classrooms, not shareholders

Built by a nonprofit, so every decision about content and support strengthens student learning rather than satisfying investors.

Understanding and fluency, built together

IM Math is designed so conceptual understanding and procedural fluency develop together, each strengthening the other. Students learn why a method works as they learn to use it, building speed and accuracy through practice that’s woven into every unit.

Daily routines build fact fluency, and centers give students repeated, game-based opportunities to practice skills from the current unit as well as ideas from earlier units and grades. Distributed practice—returning to key skills over time instead of drilling them once—strengthens automaticity while freeing up working memory for harder problems.

Students develop fluency with whole-number addition and subtraction from kindergarten through grade 4, moving from sums within 5 to multi-digit numbers. From grade 3 through grade 5, they develop fluency with multiplication and division, moving from work within 100 to multi-digit numbers. In the last unit of each grade, students revisit the major work and fluency goals of the year.

That’s what coherence looks like in practice: students build understanding and fluency together, with the curriculum reinforcing both over time. The result is stronger, more durable learning.

THE TAKEAWAY

In IM K–5 Math, understanding and fluency are built to reinforce each other, and the results follow from that design.

Measurable results, by design

Districts implementing IM Math with aligned professional learning and support have shown real, measurable gains in math proficiency.

NYC Public Schools, District 7
18% → 42%

Math proficiency in grades 3–8 over three years, while the lowest-performing level nearly halved.

Cecil County Public Schools, MD
+6.07 pts

Higher average score on the Acadience Math Assessment (grades K–4), among 251 matched students using Imagine IM.
