[UPDATE: This freebie is no longer available]
I’m a huge fan of American’s Math Teacher products (they do a lot of skill mastery) so I was thrilled to see that they are offering their first book, Mastering Essential Math Skill: Whole Numbers & Integers, for FREE in PDF format.
I’ve been going through the hard-copy book with my 3rd grader so I’m excited to have a copy that I can print directly from my laptop.
You’ll need to create an account at Teachers Pay Teachers if you don’t already have an account but it’s completely free to create one.
