Data Discussions and Visualizations 

Too often, data is pushed to the end of the year or not prioritized until the upper grades. However, when used intentionally in PK–5 classrooms, it becomes a powerful way to build mathematical thinking, fuel classroom conversations, and support students in seeing themselves as capable problem solvers. Through data discussions and visualizations, students begin to notice patterns, ask questions, and make sense of information in ways that feel both relevant and engaging. 

Supporting Social and Life Skills Development in the Classroom and Beyond 

By Susan Rose Simms 

Children are constantly learning and navigating how to understand themselves and connect with others. These everyday interactions, whether in the classroom, on the playground, or at home, help shape the skills they will carry with them for life. 

What’s Red and White All Over? 

How the Rekenrek Supports Number Sense in Pre-K–Grade 5 

By Christine Hopkinson 

The rekenrek is a versatile math tool that is visual, tactile, and affordable. Its red-and-white bead structure makes number relationships easy to see and gives students a clear, visual way to think about quantity and place value. 

This post shares eight downloadable rekenrek mini-lessons for Pre-K through Grade 5 that teachers can use to support number sense in the classroom. Each lesson highlights a specific mathematical concept and shows how the structure of the rekenrek helps students see and reason about numbers.

Exploring Montessori Materials: Building the Foundation for Lifelong Learning 

The name “Montessori” is familiar to many, often associated with early childhood education. Numerous homeschool programs and classroom teachers draw inspiration from the Montessori philosophy, particularly during a child’s formative years from preschool through early elementary. What many people don’t realize, however, is that Montessori principles apply from birth to young adulthood. 

So, what is the Montessori philosophy, and why do so many educators embrace it? At its core, Montessori emphasizes child-centered learning, allowing children to explore and progress at their own pace within a carefully prepared environment. This approach nurtures independence, curiosity, and hands-on experiences, supporting the development of the whole child academically, socially, and emotionally. 

How Research Shaped the LEAP Curriculum for Early Algebra 

As seen in EdWeek 

The LEAP Curriculum, created by TERC and sold by Didax, was recently featured in an article in EducationWeek. The article explores how early algebraic thinking develops in young children and highlighted the research behind Project LEAP. What follows is a summary of that piece along with key program insights from the LEAP authors. 

For many years, algebra has been viewed as a middle school milestone, a moment when students suddenly transition from working with numbers to working with letters. Yet research from TERC and its university partners shows that the thinking behind algebra begins much earlier. This insight became the foundation for Project LEAP, a multi-year study dedicated to understanding how young children build the ideas that prepare them for success in later algebra. The LEAP Curriculum grew directly out of this body of research, bringing early algebraic thinking into

Manipulatives Make Algebra Learning Concrete for Upper Levels 

Every middle school math classroom presents a unique set of opportunities and challenges. Students arrive with solid arithmetic skills but often struggle as they move toward abstract ideas in algebra. When lessons begin with symbols and rules alone, many students quickly lose confidence. Hands-on learning provides a bridge, giving students something concrete to think with as they make sense of new concepts. 

Making Math Stick: How Manipulatives Boost Learning Across Grade Levels 

Children make sense of the world through sight, sound, touch, and movement. Decades of cognitive and neuroscience research show that sensory experiences form the foundation for abstract thought, including mathematical reasoning. When children explore, sort, build, and compare, they develop the brain pathways that later support number sense and problem solving (Butterworth, 2019; Sarama & Clements, 2021). This idea, often called embodied cognition, highlights how physical experience shapes mental understanding. In mathematics, hands-on learning is essential.
