Math Mammoth in Cathy Duffy's 101 Top Picks!

100 Top Picks for Homeschool Curriculum You might have heard of this popular homeschool book, 100 Top Picks for Homeschool Curriculum by Cathy Duffy. Math Mammoth has been included as one of the top picks for the newest edition of this book, just coming out!

I feel honored about it... years ago, when I started working with the books, I never DREAMED it would come to this!

If you're interested in the new edition of book, Homeschool Buyers Co-op has a group buy for its digital version, ending at the end of this month.

And, if you subscribe to Cathy's newsletter at, you get a $3 discount coupon code for the printed version, I understood.

You can read her review of Math Mammoth in the book, of course, but also on her website as well:


Dear Maria,

I know you are terribly busy, but I just wanted to congratulate you on your (well deserved) recognition by Cathy Duffy. Having used MM for the past two years with my babies I know what an amazing program it is and I can't wait to complete the Light Blue program over the next few years. I recommend MM to all my homeschool friends as well as those who have kiddos struggling in math. The super-reasonable price is fabulous for those of us on very restricted budgets. I am so thankful to you for your vision and abilities and your willingness to share both with moms who are trying to make math better for our babies than it was for us. We will be MM users until there's no more material available. THANK YOU!

A sincere congratulations to you on this recognition!

Our family has been using your program for only a couple of months and we are pleased customers. It is so convenient to have all the grade levels available so if my student is struggling we can go back to the root of the problem. I am using the light blue series for four children ranging in age from 6-11. While I feel we are "behind", I also feel now that we have the tools to address the weak areas and move forward. I believe the time we are spending on this remediation will benefit them long-term.

Thank you for Math Mammoth!
Mary S.
