The Big Idea

Mathematics is a complex topic and can be intimidating to many students. Math can also be challenging for adults. Unfortunately, over 90% of school systems only test and teach a small portion of the many interconnected parts of mathematics – leaving wide gaps in students’ future learning capabilities. DMTI offers a thorough, research-based approach to math education that addresses all foundational aspects of what it means to learn, and love, mathematics.

Professional Development

DMTI offers professional development for teachers to enhance their knowledge and improve their math instruction.

Curricular Resources

DMTI offers solutions to schools and parents.


The Primary Math Assessment (PMA) can be used to predict children's areas of math strengths and limitations.

Unique Approach

The Developing Mathematical Thinking (DMT)
approach has five interrelated components.

1. Building on students’ ideas
2. Modeling the mathematics
3. Creating conceptual and procedured knowledge
4. Infusing structual language
5. Addressing misconceptions
