Build deep understanding with this essential inquiry-based mathematics curriculum
Mastering math starts with knowing the numbers. We get students started on the right path in Pre-K, but that's just the beginning. It's also about looking beyond numbers to understand how and why they work, and learning to ask the questions that lead to a thoughtful, informed approach to solving problems.
Based on research funded by the National Science Foundation (NSF), Math Expressions is a proven Pre-K–6 curriculum that helps children make sense of math by exploring, discussing, and demonstrating their understanding of key concepts. In busy, active lessons, students learn how to look deeper and choose their own path to the answers—skills that will take them far beyond the math classroom.
Looking deeper produces exceptional results
Every lesson integrates mathematical
processes and practices.
Students use authentic examples to
make sense of mathematics.
Schools see an average gain of
12–15% on state tests.
A Yearlong Study of Success
Students from eight schools across four states showed "statistically significant" improvement.
When children understand math, they're not relying on memorization. They're relying on themselves. Dr. Karen Fuson's comprehensively researched approach to teaching math is based on the way children actually learn and is used across the country because it raises student achievement.
How to think about math
The deep conceptual understanding that's the hallmark of the program leads to strong skills fluency and the ability to make generalizations within and among mathematical strands. As students grow and learn to think critically, teachers develop their own richer understanding of math through detailed instruction and embedded support.
Math Expressions is based on NSF-funded research.
Students develop an understanding of mathematics through real-world situations and visual supports.
Students learn multiple ways to solve problems, including algorithms based on reasoning.
Teaching materials embody a "learn-while-teaching" style.
Student technology builds understanding, practice, and problem solving.
- The Math Worlds augmented reality app gives students an amazingly interactive opportunity to apply what they’ve learned.
- Games in the online Math Activity Center develop fluency in math facts and operations.
- Students build concrete and pictorial relationships with digital manipulatives.
- Learners can download and practice working with content offline via HMH Player®.
Lessons build understanding through active inquiry.
Students make connections between key topics both within and across grades.
Math Talk gives students the chance to ask questions and use their MathBoards to explain and justify their solutions.
The online Student Activity Book gives young learners the tools to explore and deepen their understanding of key math concepts.

Early Learning Resources
Classroom Structures Support Understanding and Math Talk
- Students use colorful manipulatives and shape puzzle mats to develop a deep understanding of number and geometry concepts.
- Fun games and puzzle cards engage students and get them excited about mathematics.
- Daily routines include learning the count word sequence and relating to number symbols and quantities through patterns, fingers, and actions.
- Students take turns as student leaders, building confidence over time.
Research tells us that students who start kindergarten with a high level of math understanding do better in both math and reading after kindergarten. With that in mind, we developed Math Expressions Early Learning Resources to provide early learners with the understanding they need to confidently take the first and subsequent steps of their mathematics journey.
Grounded in Research
Students will benefit from teaching-learning paths and structured, repetitive experiences as recommended in “Mathematics Learning in Early Childhood: Paths toward Excellence and Equity.”
Rated as Strong by ESSA
Early Learning Resources is based on the same ESSA strong foundation and research as the rest of Math Expressions, making it an ideal transitional program for pre-kindergarten early learners.
Focused on Numbers and Geometry
Research guidelines led to a strong focus on numbers and geometry, content areas that are particularly important in early math instruction.
Playful activities help children see, discuss, and use mathematical structures, building understanding and fluency gradually and systematically.
Math Expressions facilitates learning while teaching.
- Professional development, classroom demonstration, and daily routine videos are at point of use in the Teacher Edition.
- Lessons include teaching and inquiry notes, visual models, and suggestions for Math Talk.
- Mathematical processes, practices, and learning progressions are featured in every lesson.
- Formative assessment reporting helps group students for instruction and identifies appropriate differentiation resources.
Differentiated support to encourage all students.
The Math Activity Center supports every child with Practice, Re-teach, and Challenge resources for each lesson.
Customize instruction with the Personal Math Trainer® Powered by Knewton™, an online personalized learning and assessment system with real-time reporting and adaptive practice.
Math Expressions classrooms are collaborative
