Math Mammoth Blue Series EBooks
Math Mammoth Blue Series ebooks are **worktexts** on specific math topics for grades 1-7. "Worktext" means that the ebooks contain both explanations of the concepts and lots of varied problems. It is like a textbook and workbook combined.

Each of the Blue Series books **concentrates on a few topics** only, such as addition & subtraction, place value, clock, measuring, money, multiplication, division, geometry, fractions, decimals, ratios, percent, integers, and so on. This topical arrangement makes the books suitable for many kinds of situations, such as:

- To supplement any other math curriculum;
- As a remedial material for students who are behind;
- As a review material on specific topics.

It is even possible to use the Blue Series books to piece together a complete curriculum; however, I would advice you to consider Light Blue series instead, since it IS designed to be exactly that.

The Blue Series books are **very affordable** as PDF downloads (ebooks): the prices vary from $2 to $7.00. They are also available as printed versions.

These books cover all the necessary topics for grades 1-6 and some for grade 7.

The PDF files of these ebooks are enabled for annotating. This means that the student can actually complete the PDF file on the computer, using the typewriter and drawing tools available in Acrobat Reader version 9 or higherm, or on a tablet device such as an iPad, using a PDF app that has annotating tools.
