The Big Inch

(high-density polymer Big Inches currently on backorder)


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.
