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:
