Category Description for Math Mammoth:

Theres a whole lot to like about this well-conceived and inexpensive math program. The main features of this program, according to author Maria Miller, are:

  • Focus is on conceptual understanding rather than rote problem-solving
  • Teacher instructions are right in the book; no need to buy a separate teacher book
  • Clear explanations are written for the student, so the lessons are virtually self-teaching
  • Lessons use lots of visual and pattern exercises
  • Mastery oriented:concentrates on each topic for a long time studying fewer topics per grade than with spiral
  • Emphasis is on mental math and number sense
  • Very little teacher preparation is required
  • Content aligned to Common Core Standards

These are all valid claims and sum up this approach nicely. Its linear approach is similar to that of the MCP Math program. Topics are introduced, studied in depth, then the student proceeds to the next topic. Visually, it reminds me of Developmental Math because of the extensive use of pictorial representations. Users posting online have compared the course to Singapore Math, but I don't really see much similarity. While they both emphasize conceptual learning and mental computation skills, Math Mammoth has a much more traditional feel. A distinguishing feature of this program is the authors amazing ability to simplify and clarify math processes so children can understand them easily. Even in printed form, this course is the easiest on the budget using a strictly by-grade comparison. And for those purchasing the complete program on CD (or download), the savings are even greater. Imagine getting a complete, masterfully taught math curriculum for grades 1-7 for less than $150. I would call that frugal and smart.

Each Grade Level Set consists of four components: Student Workbooks A & B, an (optional) set of Tests and Cumulative Reviews, and an Answer Key containing answers to both workbooks and tests. Currently, we carry the curriculum in print format or CD format by the grade level, Grades 1-3 and 4-7 combined on CD, and the entire course on CD. The course is also available as a download (go to site) for slightly less than the CD price. Both download and CD have colored student pages. All grade levels of printed materials are now available in your choice of black and white or color. Currently, the CDs also include bonus software, Soft-Pak - for Windows only (math, language arts and testing).

Student Workbooks A and B for each level have varying numbers of chapters, each focusing on a math topic. These are sometimes very broad. For example, one very large chapter (68 pages!) in Worktext 4-B is simply titled, “Division”. It reviews division, and then covers every facet of fourth grade division. Since division skills are being built step-by-step throughout the chapter, there’s really no need for review or testing until the end; but it does make for a long teaching unit. Each chapter begins with a short introduction. This is where you will find any teacher instruction for the chapter, including background information, strategies and ideas for teaching lesson concepts, a summary of lessons by title (including number of pages for each), and a list of Helpful Internet Resources for further exploration, practice and enrichment. If the chapter is on a skill introduced in a previous grade, the skill is reviewed before the new material is introduced. Lessons each include a complete explanation of each skill being taught, numerous examples and models (many visual) to help students understand the concepts behind the math, and a reasonable number of problems for students to work to ensure comprehension.

The lessons vary from 1-5 pages each. For planning, the author suggests simply dividing the number of pages in each book by the teaching days rather than planning to teach a lesson a day. This would generally mean covering 1-2 pages a day depending on grade level. After the last lesson in each chapter there are one or two reviews. Chapter tests are contained in the separate Tests and Cumulative Reviews Book, as are cumulative reviews (taken upon completion of each worktext chapter) and a comprehensive test for the grade level. A nice feature is the inclusion of grading instructions and scales. If remediation is indicated, the author provides a website (www. for additional math worksheets by grade level and skill. Worksheets are randomly generated within your provided parameters, so each is different.

Use the Skills Review Workbooks books alongside the Math Mammoth curriculum to review concepts that are being taught. Each book is divided into chapters that correspond with the curriculum chapters. These workbooks are optional, and are intended for those who want a spiral review. Each review in the workbook is one page in length and includes a variety of math exercises. Students might write math equations, color pictures, or solve puzzles to put their math skills to the test. Some children require more practice than others, so use only the review pages you need. Skills Review Workbooks are printed with color for a little more visual appeal, and the number of reviews vary from book to book. Answer Keys are a separate book and are also printed in color.

As mentioned briefly before, I find the author’s teaching methods very solid, efficient, and effective. Her goal is to imbue the student with an understanding of the concepts in math rather than just how to solve problems and this is evident in her instruction. She consistently shares strategies, “tricks” and revealing insights into the mysteries of math, essentially putting a teacher right on the page. An example is in teaching beginners to add numbers with sums greater than 10. She tells students that when adding 9 to a number, the 9 “really wants to be a ten”, so you should take one from the other number to make it a ten, and then add the rest. I have seen few other curriculums (see Miquon Math) that teach students alternate, flexible ways like this to approach operations. Another feature I liked in the book was using gridded workspaces for solving problems. Especially for students just starting to use multiple-digit operations, it’s helpful to get them in the habit of keeping answers neatly aligned in columns. I also like the scale problems in Grade 4’s multiplication and other chapters. These are much like the ones in CTP’s Balance Math program and very effective for understanding how equations work. There’s also a healthy balance of word problems in the lessons with realistic, practical contexts. The geometry sections are particularly good, too, with ample hands-on work. The author even includes printable manipulatives for constructing your own geometric solids.

I've been using Math Mammoth since my child was in 1st grade and we love it! Simple, clear instruction with no prep that my child can follow with minimal assistance. Teaches many ways to do the same problem, allowing children with varying learning styles to pick up the concept.

I like Maria Miller's Math Mammoth. I'm homeschooling one of my kiddos while still working and I love that this is easy to use and has teacher guidance built in.
Rebecca F on Apr 28, 2022
As an educator, I find Math Mammoth to be an ideal text to teach and master math. I am needing this text, along with 4-A, to keep handy in case one of my students needs it sooner than anticipated.
Carrie P on Jan 11, 2022
Have used Light Blue Math Mammoth for one daughter K-3, and the other in K. Both doing well, expect to continue
Amy T on Aug 2, 2021
I used this series last year and I liked how she teaches the concepts in different ways so children can learn in a way they understand.
Janice B on Jul 12, 2021
This is an excellent series with helpful videos, and plenty of writing space on the worksheets. This is mastery rather than spiral, so kids have time to truly understand one concept before moving on.
Jessica K on May 9, 2021
have heard good things, seems like it will be a good fit, some spiraling but mainly mastery based

Haley S on Jan 15, 2020
I love Math Mammoth. It nearly self-teaches, which helps me home school multiple children. It allows my independent child to soar ahead, and my straggler to, well, straggle, but do so in a way that doesn't leave gaps. We can find support on YouTube and with Kahn Academy when the explanation or practice is not enough.
Caitlin C on Sep 30, 2019
So far, one of the best math programs we've encountered for homeschooling.

Kristina M on Aug 17, 2018
Great math book! I used it with both homeschooling children from the beginning. Can't be more happy with it.
Yana B on Aug 14, 2018
After spending much time researching different options for our homeschooling math curriculum, this fit best with my expectations and state requirements for the math education of my kiddos. I also really like the fact that they have the lesson right before them, so they can independently learn, and I am there in a support role.
Amanda E on Aug 7, 2018
Love Math Mammoth and use it for all students. Very easy to teach and master.
Lara M on Jul 27, 2018
My kids have loved the samples and are really learning a lot!
Angela Z on Mar 29, 2018
Worked for my older daughter, using it as a reference and review workbook for my younger, who is learning math too fast :-) This is the BEST no-frills math curriculum available (coming from an engineer and scientist mom).
Anna W on Mar 2, 2018
Affordable, straight forward math curriculum. We've been using this since Grade 2 and are still happy with it!
Matt C. on Jan 30, 2018
My daughter home schools her children - she chose these workbooks. I'm just paying for them!
Rusty R on Jan 8, 2018
Tried 4A and liked it, so ordered 4B to finish out the year!
Karen W on Nov 8, 2017
Great Mastery-based curriculum and the workbooks are cheaper than the cost of the ink from my printer to print out pages!
Janice B on Sep 16, 2017
This is our third year with these books for our homeschool. I find them to be great teaching tools. The kids never get frustrated and they can work independently easy.
Eliza K on Sep 11, 2016
Math Mammoth is clear, concise and comprehensive. It explains the concepts well, spends enough time on each for the student to firmly grasp the concept, and has the student use it regularly to embed it in their brain. It uses word problems throughout the books. There are also concept specific workbooks if you need to brush up in certain areas. Check out their website for more details.
Tabitha M on Jan 4, 2016
Math Mammoth is the best maths curriculum I have seen.

LOVE Math Mammoth Light Blue
Math Mammoth is thorough and takes small steps on the path to mastery. There are lots and lots of practice problems , but the best part is the word problems. They are indirect and often require the student to figure out multiple steps to solve them. These books for a single grade take my daughter longer than one school year to complete because she only does one page per day. However, this doesn't bother me because I know that she are getting a very solid foundation and understanding of the math. She needs a great deal of repetition, so these books are perfect for her. My son is very quick with math, so I don't ask him to do all the problems once I can see that he understands the concept, so he may finish the grade 4 books in one year. Overall, this is a great math program and I highly recommend it.
