Math Mammoth printed books sale

Math Mammoth printed books at now at 20% off at Rainbow Resource Center!

Please note that they sell TWO versions of the books:

(1) Books in full color
(2) Books with black-and-white inside pages

BOTH have full-color covers so you cannot go by that. The full color books cost slightly more. You can mix and match if you'd like, such as by purchasing the student books in full color and the answer key and test books with black-and-white inside pages.

This promotion runs till June 2, 2017.
