Math Mammoth Blue Series books are worktexts or units on specific math topics for grades 18.
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 books in the Blue Series cover all math topics for grades 18. Please click here for a suggested order of study and gradelevel matching for the books.
The downloadable versions (PDFs) are enabled for annotating. This means that the student can complete the PDF file on the computer, using the comment tools available in Acrobat Reader version 9 or higher, or on a tablet device using a PDF app that has annotating tools.
It is even possible to use the Blue Series books as a complete math curriculum; however, it will take more planning work than using the Light Blue series. It is a cheaper option though and some people do use it as such. If you do decide to use the Blue Series as your main math curriculum, then I recommend you also check out this series of review workbooks to provide your student with mixed review lessons.
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.
Addition 1 — grade 1. Addition within 010, missing addend problems (2 + ___ = 8), word problems.

1. Is the Blue series a complete curriculum?
The Blue Series books have not been written to be a complete curriculum as such. Math Mammoth Light Blue series is the complete curriculum. The Blue Series does not contain tests or cumulative reviews, nor is it organized to go by grade levels.
However, it is possible to use the Blue Series books and "piece together" a math curriculum. This will cover all the necessary topics for grades 18.
Please keep in mind that many books in the Blue Series cover material for several grade levels in one book. The series is NOT organized exactly by grade levels.
2. Do all the workbooks come with answer keys?
Yes. All of the Blue Series books have answers appended in the worktext.
3. Can I buy the books as hardcopies (print versions)?
Yes. The Blue series books are available as printed hardcopies through Lulu.com.
4. In which order should I study the Blue Series books?
Please click here to read the answer.
5. Which book is right for my child?
You can usually find that directly from considering the math topic that your child finds difficult. Check the table of contents of the various books on that topic to find the best match. Or, check this table that lists the approximate study order and grade levels for the Blue Series books.
You can also have your child take a placement test for the Light Blue, email me the results, and I can guide you as to which Blue Series books would be best for your child.
