Rosie has a confession:
She used to dread teaching math.
After 11 years in the classroom, she was confident teaching literacy, science, social studies—everything except math. She knew something had to change, but she wasn't sure what.
Then she joined Math Success by DMTI and learned the foundations of how children actually learn mathematics.
Today? She runs a student-led kindergarten classroom where 5-year-olds co-construct learning intentions, persevere through "the pit" of productive struggle, and eagerly anticipate novel, challenging problems.
Her students don't just learn math. They love math.
The Transformation: From Skeptic to Believer
When Rosie first encountered the DMT Framework, she was skeptical.
Like many elementary teachers, Rosie had experienced math as a set of procedures to memorize, not a subject to understand. The idea that kindergarten students could conceptually understand composing and decomposing numbers seemed ambitious.
But she decided to try.
She worked with Dr. Jonathan Brendefur, founder of Math Success by DMTI, to learn the foundations of how children learn mathematics and the best ways to teach it.
Over time, something remarkable happened. She saw a massive difference in her students' confidence and achievement. The transformation was so profound that she now says she'll only teach in schools that allow her to use the Math Success by DMTI program.
The Classroom: Student-Led, Language-Rich, Misconception-Friendly
Walk into Rosie's kindergarten classroom during math time and you won't see a teacher lecturing at the front.
You'll see students:
- Co-constructing the "Learning Intention" and "Success Criteria" in language they understand
- Creating visual diagrams to represent what they're learning (because they're 5 years old)
- Communicating their thinking openly
- Being comfortable with incorrect answers and misconceptions
- Providing feedback to each other to correct thinking
This isn't just "nice classroom culture." This is deliberate pedagogy grounded in the DMT Framework.
The "Pit": Where Confidence is Built
Rosie has watched countless students struggle with challenging, novel problems.
She's also watched them persevere through what she calls "the pit"—that moment of productive struggle when the answer isn't obvious, when they have to think deeply, when they might fail. Download "The Pit" poster to use in your classroom.
And she's watched their pride and confidence explode when they emerge from the pit having solved something they didn't think they could solve.
This is the opposite of traditional math instruction, where teachers demonstrate procedures and students practice until they get it right.
In Rosie's classroom, struggle isn't failure—it's the pathway to understanding.
The Lesson: Composing and Decomposing Numbers
Consider a typical kindergarten lesson on composing and decomposing numbers (Unit 1, Lesson 4 in the Math Success curriculum).
Traditional approach: Teacher shows students that 5 can be broken into 2 and 3. Students practice with manipulatives. Worksheet follows.
Rosie's approach:
- Present a novel problem: "Show me different ways to make 5"
- Students explore using multiple strategies (counters, drawings, fingers, number lines, bar models)
- Students share their strategies with the class
- Class discusses which strategies work and why
- Misconceptions surface and are addressed through conceptual understanding, not correction
- Students reflect on what they learned and how their thinking changed
The difference? Students aren't memorizing that 5 = 2 + 3. They're understanding that numbers can be composed and decomposed in multiple ways—a foundational concept that will serve them throughout their mathematical careers.
The DMT Framework in Action
Rosie's classroom exemplifies all 5 components of the DMT Framework:
1. Taking Students' Ideas Seriously ✓
Students co-construct learning intentions. Their thinking drives the lesson. Misconceptions are valued as windows into understanding.
2. Using Multiple Strategies and Models ✓
Students use counters, drawings, fingers, number lines, bar models—multiple representations to build understanding.
3. Teaching Conceptual Before Procedural ✓
Students explore why numbers can be composed and decomposed before learning any procedures or symbols.
4. Using Structural Language ✓
Rosie uses the 6 foundational words intentionally: unit, compose, decompose, iterate, partition, equal. Kindergarteners learn to say "I can compose 5 using 2 and 3" with confidence.
5. Embracing Misconceptions and Mistakes ✓
The classroom is safe for wrong answers. Misconceptions are addressed through conceptual understanding, models, and language—not correction.
The Results: Engagement, Confidence, Achievement
Rosie reports a huge change in student engagement during math lessons.
Her students—many of whom face significant challenges (100% free lunch, 9 English learners, 3 nonverbal students)—don't just participate. They LOVE math.
They know challenging problems are coming. They look forward to them. They feel successful when they solve them.
What This Means for Your Classroom
Rosie's transformation isn't unique. Teachers across the country are experiencing similar shifts when they learn the foundations of how children learn mathematics.
You don't need to be a "math person" to teach math well.
You need:
- Understanding of how children learn mathematics
- Tools to build conceptual understanding before procedures
- Language to help students communicate their thinking
- Strategies to embrace and address misconceptions
- Support to persevere through your own "pit" of learning
Rosie got all of this through Math Success by DMTI.
So can you.
