Fractions as division — 3 pizzas shared equally among 4 people, each person receiving 3/4 of a pizza, with the DMT Framework components Unit, Partition, Equal, Iterate, Compose, and Decompose showing how the vinculum means 'divided by' and why 3 ÷ 4 = 3/4 is the critical connection for algebra readiness

Teaching Fractions as Division: Why 3/4 = 3 ÷ 4 Is the Connection That Unlocks Algebra Readiness

Most students learn fractions and division as separate topics and never connect that a fraction IS division — that the vinculum means "divided by." The DMT Framework's Unit, Partition, Equal, and Iterate components build this critical connection with the complete Fair Share Protocol, a 30-minute CRA activity that transforms fractions from mysterious symbols into meaningful quotients that prepare students for algebra.

Fraction assessment with the DMT Framework — a diagnostic dashboard showing six gauges for Unit, Partition, Iterate, Compose, Decompose, and Equal, with fraction bars, number lines, and area models as assessment items, revealing which conceptual components are secure and which need support

Fraction Assessment: Why Most Tests Miss What Students Actually Understand — and How the DMT Framework Fixes It

Traditional fraction assessments tell you whether students got the right answer — not whether they understand why. The DMT Framework's six components (Unit, Partition, Iterate, Compose, Decompose, Equal) provide a diagnostic assessment lens that reveals exactly which conceptual building blocks are secure and which are missing, with a complete 6-item assessment protocol that takes 20 minutes and tells you more than any unit test ever could.

Division word problems solved with the DMT Framework — 24 dots partitioned into 4 equal groups of 6 (partitive division) and grouped into groups of 6 showing 4 groups (measurement division), with the six DMT components: Unit, Compose, Decompose, Iterate, Partition, and Equal, showing how structured problem-solving transforms division comprehension

Division Word Problems: Why Students Can Divide But Can't Solve — and How the DMT Framework Changes Everything

Students can fire off 24÷6=4 in seconds but freeze at "24 books shared equally among 6 shelves — how many per shelf?" The DMT Framework's six components transform division word problems from comprehension barriers into structured problem-solving opportunities, with the complete Division Problem-Solving Protocol covering both partitive and measurement division.

Fraction number talks — a classroom circle with students sharing fraction reasoning strategies, speech bubbles showing different ways to think about 3/4 using DMT Framework components Unit, Partition, Iterate, Compose, Decompose, and Equal, with fraction bars, number lines, and area models as visual thinking tools

Fraction Number Talks: Building Fraction Sense Through Daily Discourse

Number talks transformed whole-number instruction — but they disappear the moment fractions show up. The DMT Framework's six components provide the perfect structure for designing fraction number talks that build genuine fraction sense, with five talk structures, a 15-minute protocol, and a complete 5-day ready-to-use plan.

Fraction Intervention Strategies: Why Reteaching the Same Way Never Works

When students fall behind in fractions, reteaching the same content slower doesn't fix the missing conceptual infrastructure. The DMT Framework's six components provide a diagnostic lens that pinpoints exactly where understanding broke down — with a complete 6-session Tier 2 intervention protocol and targeted activities for each component.

DMT Framework Equal component — equal groups in multiplication, equal parts in fractions, equal units in measurement, equal partitioning in division, and equal intervals on a number line, showing how Equal ensures fairness across every math domain

Equal: The DMT Framework Component That Makes Fairness Mathematical

Students shade "3 out of 4 pieces" and call it 3/4 — even when pieces are clearly different sizes. The DMT Framework's Equal component — the constraint that every part must be the same size — is the fairness construct behind fractions, multiplication, division, measurement, and equations, with a complete 25-minute Equal Check Investigation.

DMT Framework Decompose component — breaking 48 into 40+8, 7/4 into 4/4+3/4, and 16×25 into 4×25×4, showing how Decompose creates mathematical flexibility across place value, fractions, and multiplication

Decompose: The DMT Framework Component That Creates Mathematical Flexibility

Students who see numbers as fixed wholes are locked into one rigid path through every problem. The DMT Framework's Decompose component — breaking wholes into meaningful parts — is the flexibility engine behind mental math, fraction conversion, partial products, and subtraction regrouping, with a complete 30-minute Decompose Investigation.

Unit: The DMT Framework Component That Defines What Counts as One

"What counts as one?" seems simple — until you realize it's the root construct behind place value, fractions, multiplication, and measurement. Learn why Unit is the prerequisite for every other DMT component and how the 30-minute Unit Shift Investigation builds the flexibility students need.
