Do The Math

Help Students Build Numerical Reasoning

Math is about more than finding the correct answer. It's about using numerical reasoning to find the best strategy for solving a problem. Created by Marilyn Burns, one of America's most trusted math educators, and a team of master educators, Do The Math® provides flexible, classroom-tested instruction for building numerical reasoning and confidence. Whether used for core instruction in numerical reasoning, pull-out intervention, or summer school settings, Do The Math provides effective instruction at any elementary grade level.

Every Child Deserves a Confident Start

Created by award-winning educator Marilyn Burns

Supports any Response to Intervention (RTI) strategy

Can be used with all core programs as supplemental or intervention

Every student can succeed

Build a solid mathematical foundation with classroom-tested lessons

"Classroom tested" means there's plenty of support in each module's 30 half-hour lessons. Teachers build capacity as students move from basic conceptual understanding to skills development in addition and subtraction, multiplication, division, and fractions.

  • Addition and Subtraction
    Four Do The Math Teacher Guide books for addition and subtraction

    Supports the development of quantity by using benchmark numbers, thinking flexibly about composing and decomposing numbers, and building facility with figuring sums.

    Builds on the big idea that “10” is an organizer for our number system.

    Reinforces addition and subtraction as inverse operations and teaches the three meanings of subtraction: take-away, missing parts, and comparison problems.

    Applies these big ideas to calculations with greater numbers and provides strategies for solving word problems.

  • Multiplication
    Three Do The Math Teacher Guide books for multiplication

    Provides visual and contextual models to help students understand the meaning of multiplication, supporting the shift from thinking additively to thinking multiplicatively.

    B: FACTS THROUGH 12x12
    Uses an array model to represent the basic facts and demonstrate key concepts and strategies for multiplication.

    Develops strategies for making estimates and computing products with two- and three-digit factors, using the distributive property and multiplying by multiples of 10.

  • Division
    Three Do The Math Teacher Guide books for division

    Builds upon the idea that division is inverse to multiplication and provides computational methods for solving division problems, using contextual and concrete methods to support the two meanings of division—sharing and ungrouping.

    B: FACTS THROUGH 100÷10
    Applies the inverse relationship between multiplication and division to make sense of divisibility and the concept of taking out a quantity by groups of 10.

    C: DIVIDENDS TO 1000
    Extends to dividing two- and three-digit dividends by two-digit divisors, engages students in exploring divisibility, and provides experiences with solving contextual problems involving greater numbers.

  • Fractions
    Three Do The Math Teacher Guide books for fractions

    Connects and builds upon the big ideas of whole numbers as they apply to fractions, using concrete materials to help students give meaning to the abstract idea of fractions.

    Helps students learn key strategies for comparing and ordering fractions while keeping the instructional focus on the meaning of the fractions being compared.

    Builds on what students have learned in order to develop the computational tools and strategies to add and subtract fractions, including improper fractions and mixed numbers with like and unlike denominators.

Student Engagement

Strategically placed formative assessments support students’ progress.

Middle-of-module assessment

Pre- and post-module assessments
Students complete online assessments for a pre-module snapshot of what they know and a post-module portrait of all they’ve learned.

Letters from Marilyn
Detailed preparation materials before each set of five lessons include Letters From Marilyn.

Step-by-step instruction
Every lesson begins with objectives, and then it’s on to detailed, step-by-step instruction.

Mid-module assessments
Every fifth lesson offers an assessment so teachers can regularly monitor student progress.

Hands-on learning helps build conceptual understanding

Summer School

Unlock the math potential in every student

A young girl is writing.

Do The Math Summer School helps students in Grades 1–5 rebuild their math foundation. Designed for at-risk and struggling students, as well as those who require more practice, the program provides the skills and understanding students need to progress to grade-level proficiency during the school year.

Summer school specific design
Do The Math experts and authors created detailed Planning Guides that address a variety of summer school implementations.

Easy to implement
From day one, teachers have the embedded professional learning and point-of-use support they need to confidently guide students through summer math.

Rebuilds a solid foundation
With scaffolded instruction, students progress from basics to more complex operational work and rebuild their understanding of key math concepts.

Engaging for students
Classroom-tested instructional practices facilitate differentiation and meet the needs of every student.

Professional Development

Do The Math Getting Started PD and Coaching

Teachers attending Do The Math Seminar.

Do The Math Getting Started PD develops teachers’ understanding of the Do The Math supplemental program and how its classroom-tested instruction builds students’ numerical reasoning. Teachers learn how to support the development of their students’ understanding and skills with whole numbers and fractions by using Do The Math lessons, games, children’s literature, and assessments.

During Do The Math Coaching coaches work with school leaders and classroom teachers to build on the Getting Started PD experience, creating learning partnerships that are sustainable, data-driven, and customized to participants’ particular needs.
