Math Success by DMTI launches K-6 math program for teachers

Math Success by DMTI has launched mathsuccess.io, a teacher-focused K-6 math program that combines professional learning with curriculum resources and direct access for educators. The Boise-based institute says the model is designed to help teachers improve student understanding, with pricing set at $21 a month for individuals or $1,000 a year per school building.

Why it matters: - Math Success shifts math support from district-only professional development to direct access for individual teachers. - The program targets a core problem in math instruction: helping teachers understand student thinking well enough to teach concepts, not just procedures. - DMTI says the model is especially relevant for students who struggle most in mathematics.

What happened: - Math Success by DMTI launched mathsuccess.io in Boise in September 2026. - The program is a teacher-focused, conceptual-first K-6 mathematics platform. - Math Success combines teacher preparation, professional development, and curricular resources. - The program is built on more than 40 years of research at the intersection of mathematics, psychology, and instruction. - Individual educators can enroll for $21 a month. - Schools can enroll every teacher in a building for $1,000 a year.

The details: - The DMT Framework uses visual models, structural mathematical language, and reasoning before moving to procedures. - The goal is for students to understand why mathematics works and to apply reasoning strategies in new situations. - DMTI cites a cluster-randomized study of 25 schools and 4,618 students that found higher math scores in DMT schools than in control schools. - The school-level effect in that study was 0.09 standard deviations, with the largest gains among students with the lowest prior math performance. - The study was peer-reviewed and published in the International Journal of Science and Mathematics Education. - A separate federally funded randomized study assigned eight schools to DMT or control over two years. - Students in grades 2-5 in that study gained 0.2 standard deviations over the control group. - An independent evaluation by RMC Research Corporation found 79.2% of students in DMT classrooms scored proficient or advanced in mathematics, compared with 65.7% in comparison classrooms. - That gap held for three years. - The DMT schools in the evaluation served more students in poverty and more English learners than the comparison schools. - Math Success says the DMT Framework has been used in more than 300 schools. - DMTI says the framework has reached more than 350,000 students and prepared more than 14,000 teachers.

Between the lines: - The launch package pairs curriculum with teacher development, which suggests DMTI sees teacher knowledge as the lever for student gains. - The strongest reported effects among lower-performing students point to a strategy aimed at closing gaps, not just raising average performance. - The company is positioning the product as both a software-style subscription and a schoolwide professional learning purchase, which broadens its market beyond traditional district contracts.

What's next: - DMTI plans to keep supporting teachers through direct learning, coaching, and live Office Hours. - Jonathan Brendefur hosts live Office Hours every Monday at 3:30 pm Mountain Time, and journalists are welcome to join. - More information is available at mathsuccess.io.

The bottom line: - Math Success is betting that stronger teacher understanding of mathematics can translate into stronger student outcomes, especially for students furthest behind.
