From counting & writing numbers to reasoning & justification?!

Sound familiar?

Math time at your table is a special place.

“Do I look forward to math? Well....”

“I like math, am not a “math person”, but I do enjoy teaching it. There's just something missing...”

“That lesson was AMAZING! I can't wait for the next one. I could do this all day!”

Children have more fun, get enthusiastic about math, and build the confidence to speak up and explain, setting a course for the years ahead.what math time can feel like at your table

What your K-2 child can actually do

Counting is one thing. Using a strategy to do it quicker, explaining the strategy, then verifying it works and showing it with a model; that's different.

When “how do you know?” is a normal question in the early years, explaining becomes a habit for life.

Two topics quietly predict the power levers: spatial reasoning and measurement.

Students who memorize facts but never build spatial reasoning hit a wall in the upper grades. Students with shaky facts but strong spatial reasoning catch up easily. And it can be learned: every DMTI lesson has children building, drawing, and explaining with visual proportional models. That modeling is the practice, along with measuring, comparing, and composing shapes.

Where this goes next: subtraction that follows

When your child composes a new ten and sees 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 your child builds, draws, and explains. That's fluency that survives past the timed test. Watch the free Grade 2 lesson →

Built in schools. Now in your homeroom.

This is not a homeschool experiment. It is the program and the people 300+ schools brought in for their classrooms, opened up to families. The lessons are the same ones that produced the numbers below. The weekly live calls are the same researchers behind them.

25 schools

4,618 students in the peer-reviewed cluster-randomized study

2.71

effect size (Istation), nearly unprecedented in math PD research

79.2% vs 65.7%

proficient or advanced, DMT classrooms vs comparison (RMC Research, independent evaluation)

Who benefits most? The students furthest behind. In that study, the students who started with the lowest math performance made the largest gains. Independent evaluation (RMC Research): 79.2% of students in DMT classrooms proficient or advanced vs 65.7% in comparison classrooms, with DMT schools serving more students in poverty and more English learners. If your child is behind, this is built for them. If your child is ahead, this is built to keep them thinking.

Two words do heavy lifting: unit and compose.

The most powerful vocabulary in K-2 is not a sight word list. It is the precise language of mathematics, and these two words appear everywhere from here to college. Your child will use them for the next twelve years. You will know exactly what they mean.

unit

The thing being counted or measured. A unit of 1 vs. a unit of 10 or 100. Fahrenheit. Watts. Halves. Quarters. Unit. A kinder through forever word.

compose

To put together. K-2 students compose 6 from 4 and 2, compose shapes from pattern blocks, compose tens from ones.

compose is everywhere: compose numbers compose shapes compose music compose a story a composition book

Because the words are precise, they align you and your child on the same idea. When we're consistent with compose, decompose, unit, iterate, partition, equal from K-2 on, the math conversation never has to restart. It's the same through college and beyond.

“It is so fulfilling to send them away with real foundational skills. I'm so happy to be able to teach this way.”

Students read the scene and say the math out loud: three and two composes five.

CLASSROOM MOMENT · MS. ASHCRAFT'S CLASS

“It's amazing to me how much those kindergartners understand. People say don't use big words with these little kindergartners. Yeah, they can, and they actually love them, because that makes them feel so smart.”

MRS. HOCHSTRASSER · KINDERGARTEN TEACHER

“I haven't had to pull kids through math for probably the last four or five years... we give them the language they need to express their thinking.”

MRS. STUCKI · KINDERGARTEN TEACHER

Before DMTI: “Great math instruction in kindergarten was extremely boring. If you follow a box curriculum and repeat counting to 100 a thousand times across the school year... the students aren't growing: they can't visualize or see what's happening within the mathematics.”

After one year: “Math became my favorite part of the school day... it made a lot of sense to the students, and my students started growing within just a couple of months' time. They were already hitting end-of-the-year benchmarks.” Rosie Ashcraft, from her interview above

“Despite extraordinary barriers: nonverbal students, 3-month absences, working memory challenges, our students grew. These kids aren't just saying math words anymore. They can explain them and show models to back it up.” Rosie Ashcraft, kindergarten teacher, on the growth and the math talk in her own classroom.

The Math Activity Pack, shipped to your door.

Hands need things to hold. The pack is the physical side of the program: real manipulatives with a storage bag and activity guides that use them, the same activities our coaches run in classrooms.

Math Activity Pack manipulatives: pattern blocks, counters, and cards (pack photo coming)

Activity cards and games from the Math Activity Pack (pack photo coming)

K-2 Pack

Chips, pattern blocks, multi-sided dice, cards, wooden blocks, and connecting cubes
Premium Printed Activity Cards included
Includes 1 full year of portal access
Storage bag, sized for the homeroom

K-6 Pack

Everything in the K-2 Pack, scaled through 6th grade
Stir sticks and patty paper for fractions, geometry, and measurement
Premium Printed Activity Cards included
Includes 1 full year of portal access
Storage bag + activity guides included

Every pack comes with a full year of Math Success. See the two ways to start.

This year is the course-setting year.

Early math does more than hit benchmarks: it jumpstarts reasoning itself. The language (unit, compose, decompose) and the models (number line, bar model) a child learns in K-2 are the same ones that carry them through fractions, algebra, and college. Nothing to unlearn. Everything builds.

Number seen, composed, and explained out loud

in elementary

Fractions, place value, multiplication: same words, bigger numbers

in high school & beyond

Reasoning that scales: models still work, language still precise

$Dr. Sam Strother teaching fractions at the board$ Fraction questions? He's got them.

We listen first

Your child, your pace, your days. You tell us what math time actually looks like at your table, and we start there, not with a script.

We build the plan together

Diagnostic → instruction → activities that close the gap, mapped to your child. You'll know exactly what to do tomorrow and why it works.

We stay in the room

Weekly live calls with Dr. Brendefur & Dr. Ismail, portal Q&A answered by people who've taught the lesson. When your child hits a wall, we're there.

“Effective mathematics instruction isn’t more complicated. When the adults understand the mathematics and what to look for in student thinking, they can focus on what matters most, and the work gets easier, not harder.”

Every parent is in a different place. Our goal is to meet you where you are, help you understand the mathematics and your child’s thinking, and make good decisions about what to do next.

Tell us about one concept your child is stuck on, or one lesson that keeps falling flat, and we will build the plan with you. That is the partnership: parent-led, expert-backed. We do not push a system downward; we listen, advise, question, and support.

Questions teachers ask before they join

Straight answers, the same ones we'd give you on a call.

Am I qualified to teach this? I'm not a math person.

Yes, and you will understand the math better as you go, alongside your child. Every lesson is demonstrated on video first: watch the teaching, then bring it to the table with the script and the models already in your hands. When you want a person, Office Hours is every Monday, and the people answering are the researchers behind the program.

How much time does this take each day?

About fifteen minutes at the table. The lesson video, the printable, and the exact language to use are all in the lesson. Most families start with one routine a week and grow from there.

What if my child is behind? What if they're ahead?

Both are the design case. In the research, the students who started furthest behind made the largest gains, and the diagnostics find the gap and hand you the activities that close it. Children already ahead get the harder thing: explaining, defending, and proving, not just bigger numbers.

Is it aligned to standards?

Yes. The lessons target the concepts grade-level standards expect (number sense, place value, the operations, fractions), so whatever your state requires for homeschool reporting, this covers the concepts underneath it.

Do I need special tech or a printer?

Printables print on any printer; the demo lessons and interactive games run in your browser. Nothing to install. The Math Activity Pack adds the hands-on manipulatives, shipped to your door.

What if I can't make the live calls?

Coaching is live and on demand. Sessions live in the portal, so you can catch up whenever it works. Office Hours runs every Monday at 3:30pm Mountain if you want it live.

How does billing and canceling work?

$21/month for up to 2 students, $10/month for each additional student ($100/yr on the yearly plan). Month to month, no contract. Cancel anytime in one click, and everything you've downloaded is yours to keep. If it doesn't make math time clearer within 30 days of your first charge, we refund you. No forms.
