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.

Math Mammoth is a fantastic curriculum! Maria lays out the concepts in a way that the child has an understanding of the basics and builds upon it until mastery. After 14 years of homeschooling (so far!) Math Mammoth is the best math curriculum I have used. (I have used many!)

We've been using the Math Mammoth program for years. This is for my third student. I like the variety of exercises for each concept, and that it takes a deep dive into each topic. I build in review by circling back around.
Christine R on Aug 1, 2021
Math Mammoth helps us understand concepts quite nicely, and is easy to teach!
Amy R on Feb 9, 2021
We are almost finished with 3-A and need this to continue with our math this year.

Good, mastery-based (non-spiraling) math curriculum that is inexpensive.
Hanna L on Aug 7, 2019
I have been using the downloaded version this summer to tutor my grandchildren. It is less expensive to buy the printed than the download version. It is 16 cents a page at Office Depot to run the books.
cynthia s on Aug 4, 2019
We've used Math Mammoth for years for two kids and love it!
Horrex K on Jun 26, 2019
This student will prepare this summer with this worktext in Math, 3B, and move onto the next in the series, 4A, to build a better foundation for middle school.
Dawn M on Jun 22, 2019
I have the digital download and have used Math Mammoth for 6 years at all levels. It's my favorite math curriculum for elementary, and I teach high school math at our co-op and formerly in a private school. We found MM3 about equivalent to Saxon 5/4. My eldest completed Saxon 5/4 in her last year of private school with an A, but when we switched to Math Mammoth, we went back and covered a few sections from MM3 that had not been covered well in Saxon before moving on to Math Mammoth 4.
Jennifer D on May 17, 2019
This series is very thorough. We do not feel rushed while learning.
emily on Mar 29, 2019
We used the Math Mammoth Light Blue Series for Grades 1 & 2 with both of my girls last year and made great progress in math! I really love how the series explains math concepts and that it is open and go.

Elvira D on Sep 15, 2018
My daughter needs additional practice and help when she's working through concepts. She can get the numbers, but it's the logic and steps she needs help with and this looks like it will help with that as she works through the problems.
Michael P on Apr 7, 2018
I love Math Mammoth! Maria Miller makes math fun!
Antonina T on Feb 4, 2018
it fits the skills that I am currently teaching and looks to be a wonderful resource.
melissa w on Nov 15, 2017
I love Math Mammoth's approach to math. Information is presented and taught in an orderly fashion. There is not endless repetition, but concepts are built upon and revisited frequently with end of chapter reviews.
Jennifer P on Oct 30, 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
I felt it was a good fit for my son.
Miriam D on Mar 31, 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
Have previously used and it is a good product.
Kim O on Jul 14, 2016
Have been using this with one child and am ordering for the next child. These books are great for teaching full understanding of concepts and mental math. They are working great for us!
Abby B on May 9, 2016
We are using Math Mammoth for our homeschool.
Stephanie C on Feb 7, 2016
I need help with math in our homeschool.
Lisa S on Jan 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

Exactly what we needed to cover a few topics he never learned using MUS. His transition this fall should now go smoothly! Easy to follow instructions meant he was able to do it pretty much independently.
