The Big Inch

(Sold at the link here!)

At the core of our curriculum is The Big Inch (U.S. Patent #7,632,099 and #8,070,493). The Big Inch 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.

The curriculum includes a downloadable, printable 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 take this course?

The online curriculum has a downloadable, printable of The Big Inch blocks, markers, and number line for you to use. If using the printable instead of a physical Big Inch, we recommend printing on heavy weight paper or photo paper.

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 HammerMath to teach to the standards. We believe in teaching in a way that sticks with you for life! Our goal is to help students understand and visualize hard-to-grasp concepts of fractions, measurement, and scaling. HammerMath's method is based on 30 years of working with students teaching them on the application of math based on real-world construction and architectural design principals.

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.
