About Us

Our mission at the Developing Mathematical Thinking Institute is to help students, educators, and parents understand, use, and love mathematics.  Too often, math educators are guided by textbooks, testing materials, and teacher training programs that are not aligned with key research findings on how to prevent fundamental misunderstandings, avoid long-term struggles in mathematics, and ultimately create a lack of confidence in students. DMTI can help reverse these trends with a comprehensive system of support that empowers students, teachers, school leaders, and families.

Our program is based on 20+ years of research and experience at all grade levels. We focus on the most critical math topics and provide a clear, carefully sequenced progression that leads to future success. We begin in primary schools, where teachers frequently have a strong background in language arts and literacy, but lack confidence and mastery in teaching mathematics. Building on these early learning experiences,we connect content across grade levels and provide educators clear and consistent guidance on how to remedy learning difficulties as well as techniques to extend opportunities for high-achieving students.

With our professional development, we help teachers and educators implement the DMT Framework that builds on students’ ideas, strengthens academic vocabulary, encourages problem solving, and ensures students are able to model and communicate about mathematics.
