Place value students build and see — units they compose themselves. Subtraction that runs on the same models as addition. Fluency from strategy, not another worksheet of naked numbers. Free to start, today.

We know what the primary years actually feel like — because we've been in the room.
When students compose a new ten and see it, 47 + 25 becomes something they can reason through. When subtraction runs on the same number line and bar models they already used for addition, it arrives as the same idea in reverse — not a new procedure to survive.
That's real place value: units students build, draw, and explain. That's fluency that survives past November. Watch the free Grade 2 lesson →
Real teachers. Real classrooms. Captured on tape.
Dramatic gains — the kind you can point to on the assessments and see in how students talk about the math.
“This is it. This is how to teach math.”
“These kids aren't just saying math words anymore. They can explain them and show models to back it up.” — Rosie Ashcraft · and Principal Chinita Irby: “In 14 years, I've never seen a company come in and support the children directly. DMTI works with the teachers and the students side by side.”
The Grades 1-2 Pack is open right now, no trial needed. Yours to keep whether or not you ever enroll.
Place value & the operations — a full lesson taught, with practice and printables that go with it.

“The primary years are where place value and the operations are won or lost — and most programs teach the column before the unit. Let me show you the version where regrouping isn't a mystery.”
The people behind 30+ years of classroom research don't hand you a binder and disappear. They're in the portal, on the weekly calls, and — when you need it — building a plan for your students with you.
Coach in the room, number line up
PD that respects your time
Fraction questions? He's got them.
Your classroom, your students, your constraints. You tell us what Tuesday actually looks like — we start there, not with a script.
Diagnostic → instruction → intervention, mapped to your roster. You'll know exactly what to do tomorrow and why it works.
Weekly live calls with Dr. Brendefur & Dr. Ismail, portal Q&A answered by people who've taught the lesson. When you hit a wall, we're there.
Tell us about one student who's stuck — or one lesson that keeps falling flat — and we'll help you build the plan for it. That's the partnership: teacher-led, expert-backed. We don't push a system downward; we listen, advise, question, and support.
This is what each part is worth on its own. Inside the Complete Math Success Program, it's all yours — built around you, the teacher.
Every line is included in your membership
Plus at least an hour of expert time free — and as many questions as you can ask, answered. Start with 7 days free, and everything you download is yours to print and keep — FOREVER.
Subtraction gets to be easy. You don't need one more thing on your plate — you need a clearer path through it. One routine this week; the rest builds from there.
Straight answers — the same ones we'd give you on a call.
No — it supplements it. The models, routines, and assessments deepen how your students think about the math you're already required to teach, alongside your adopted curriculum.
The lessons target the concepts your grade-level standards expect — number sense, place value, the operations, fractions — and we'll help you map them onto your district's pacing.
Less than you'd think. Lessons come with plans, printables, and practice built in — most teachers start with one routine a week and grow from there.
Printables print on any printer; the demo lessons and interactive games run in your browser. Nothing to install.
Coaching is live and on demand — sessions live in the portal, so you can catch up whenever it works.
