At Hammer, students don't just take math;

they work with it!

HammerMath's Architectural Design Course is designed to help students build a deeper understanding of fractions and measurement fundamentals through real-world application using architectural design principles. At the core of our curriculum is our patented fraction manipulative, The Big Inch (sold separately here). 

After learning fractions, students have fun working with area and perimeter through creative, hands-on assignments. Now, they are ready for architectural design! Students stretch their imagination and dream big by learning how to draw house plans to 1/4" scale and to design their own dream home. HammerMath builds the understanding of critical math concepts preparing K-12 students to adult learners for higher-level mathematics.


The Big Inch

(sold separately)

The Big Inch (U.S. Patent #7,632,099 and #8,070,493) is the only math manipulative that combines measurement and fractions allowing students to physically apply the algorithms of fractions. 

The Big Inch is designed for students to physically create their own fraction problems and present their findings to the class. This unique methodology of combining color and number helps students understand more than just correct answers. Students gain true understanding about the physical space connected to numbers, patterns, and measurement simultaneously developing pre-algebraic thinking. Made of dense, durable plastic, The Big Inch will last for years to come.

Both the Teacher Edition and Student Edition comes with a downloadable, printable PDF of The Big Inch blocks, markers, and number line.

The Big Inch can be purchased separately from the curriculum. To order or learn more about The Big Inch, click HERE.

Frequently Asked Questions

When does the course start?

HammerMath is a manual, self-paced course. When you sign up you will automatically receive an email with login access to the course. You can start anytime.

Do I have to purchase The Big Inch math manipulative in order to teach this course?

The online curriculum has a downloadable, printable PDF of The Big Inch blocks, markers, and number line for you and your students. If using this instead of a physical Big Inch, we recommend printing on heavy weight paper or photo paper. Students can also glue the Big Inch printable to poster board.

What is the difference between the Teacher Edition and Student Edition of this course?

Both courses have the same core curriculum. The main difference is the Teacher Edition features lesson plans, professional development videos, teaching tips, and downloadable discovery worksheets. The Student Version features Perry Wilson, the creator of the program, walking students through the lessons. The student version also features "brain game" quizzes at the end of each lesson that can be emailed to the teacher upon completion. These quizzes are a great way to track your students' progress.

Each Teacher Edition comes with the Student Edition that you can use in the classroom. Individual student logins for your students can be purchased separately by contacting us at [email protected].

What math standards does HammerMath meet?

HammerMath was designed to go beyond the traditional textbook. HammerMath is a teaching supplement that can go alongside any standard math curriculum. We did not design Hammer to teach the standards. We don't believe in teaching students how to learn for a test. We believe in teaching in a way that kids learn! Hammer helps students understand and visualize the hard-to-grasp concepts of fractions, measurement, and scaling, to help prepare them to be problem solvers and thinkers. The HammerMath method of teaching is based on 30 years of teaching students the application of math based on real-world construction and architectural design principals. It's a better way to teach!

Can I sanitize The Big Inch?

Yes! The Big Inch is now made of dense durable plastic that can be sanitized in-between uses. Avoid spraying cleaner directly on the number line.
