Our Story

The name Didax comes from the Greek didaktikos, meaning "to teach". We can't think of any more important activity.

For over thirty years, we've specialized in helping educators to address individual learning styles and diverse student needs. Since their introduction in the 70's, more teachers have used our Unifix ® Cubes than any other manipulative in the world. Each year we introduce more innovative hands-on, print, and software tools to make teachers more successful.

Almost all our products come directly from teachers, and we are always available to consider your ideas, needs, or suggestions. Just email our president, Brian Scarlett at brian@didax.com and he will respond personally.

We serve you from our offices and warehouse in Rowley, Massachusetts on the North Shore of Boston. Our international publishing partner is RIC Publications of Perth, Western Australia. Together we serve teachers all over the globe.

Didax is proud to be a member of The Association of Educational Publishers, The International Reading Association, The National Council of Teachers of Mathematics and The National School Supply and Equipment Association.
