Math Mammoth Blue Series books are worktexts or units on specific math topics.
A worktext means that each book includes both the explanations of the concepts and lots of varied problems. Thus, these books combine the textbook and workbook into one.
Each book in the series 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 situations, such as:
The video below explains the basics of the Blue Series books:
It is even possible to use the Blue Series books as a complete math curriculum; however, in that case, I recommend you to check out Math Mammoth Light Blue series, since it is designed to be exactly that.

The books in the Blue Series currently cover all necessary topics for grades 17. Please click here for a suggested order of study and gradelevel matching for the Blue Series books.
The downloadable versions (PDFs) are enabled for annotating. This means that the student can complete the PDF file on the computer, using the typewriter and drawing tools available in Acrobat Reader version 9 or higher, or on a tablet device such as an iPad, using a PDF app that has annotating tools.
These books are also available as Spanish versions, which is very useful for English language learners (ESL, EEL, ESOL students). The students can use both the English and Spanish books (Math Mammoth and Mamut Matemáticas) as their math curriculum. If they cannot understand the English version, they can check the corresponding book in Spanish and understand the math from there — and also learn English at the same time.
The gradelevels mentioned are recommendations only. The books themselves do not mention any grade levels and are usually usable across several grade levels.
