One of my older boys' current math curriculum lacks the repetition and time needed to really solidify the multiplication and division facts. My 2 younger sons use a curriculum that is very heavy on the mastery of the basic math subjects, but don't offer a lot of "extras" like time, money or measurement. So when I was given the opportunity to review Math Mammoth, I decided to choose their Blue Series, which is a series of worktexts that cover specific topics meant to be used as a supplement, extra practice or just as review.
Math Mammoth's Blue Series is inexpensively priced and available for PDF download, with a print or CD option also available. The worktexts cover most topics up to grade 6, with some grade 7 topics as well.
I choose 4 books based on areas I thought my boys needed the most work: Clock, US Money, Multiplication and Division 3 and Fractions 2.
My 3rd and 1st graders used the Money and Clock books, while my 5th grader used the Multiplication and Division and Fractions books. We used them in addition to their current math curriculum to touch on topics not covered and for add practice on topics that were proving more difficult to master.
What did we think?
Over all Math Mammoth has a lot of positives.
- The Worktexts are in inclusive. They serve as the text books, work book and answer key all in one.
- I like that there is a PDF option. Not only does this offer a less expensive option (only $2-$7 per e-book), but for those with multiple children, it saves time and money.
- The individual books are intensive enough to provide topic mastery by the completion of the book.
- Math Mammoth gives you all sorts of options from the Light Blue Series which is a full curriculum to a mix and match curriculum using the Blue Series or as a supplement curriculum. There is something for everyone.
- Math Mammoth is self-teaching, with very little prep work for the parent/teacher.
What didn't work for us:
- Switching curriculum is hard, and while I do think it is important to learn how to do math, no matter how it is presented, my older son didn't care for how the multiplication was presented. (That being said, his multiplication did improve.)
- I personally didn't like how the clock book was presented. I can see how young children, with no prior experience telling time, might be okay with starting with a one handed clock. I found it unusual and confusing.
