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.

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-B, to keep handy in case one of my students needs it sooner than I anticipated.
Carrie P on Jan 11, 2022
To supplement areas where my child needs more practice.
Lori G on Oct 5, 2021
I was burned out on Saxon math and dreaded the idea of teaching it again this year. I like the idea of these math books and how the years worth of work is split into two books. Since the cost is so reasonable I figured we could try them with out too much expense. I also love that the author offers free videos of her teaching the work. She is very homeschool friendly!
elise f on Aug 9, 2021
I like how there are free vidoes of instruction if your child doesn't understand the way you explain things.
Janice B on Jul 12, 2021
have heard good things, seems like it will be a good fit, some spiraling but mainly mastery based, also a great value with online helps included

A struggling 5th grader is unprepared for middle school and this summer she is going through this worktext, 4A, after finishing the previous worktext, 3B.
Dawn M on Jun 22, 2019
Trying to see if we can get through a whole year of math. I have the light-blue series for different topics for grades 1-3, but need the whole year all at a glance rather than topics for my 4th grader.

best math curriculum out there
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
I started my oldest two in RightStart Math and loved the foundation it laid for them, but I needed something that would provide more independence as my third one came along. Now all three do MM and I love how the workbook contains the textbook so they can learn to work independently. MM provides lots of review and wonderful explanations/instruction. It works well for us. Oh, and I especially love all the word problems!

Very complete curriculum, from our older daughter's experiences.
Alicia T on Mar 20, 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
For home school or remediation, this curriculum is very well developed and printed in a format that is student & teacher friendly. I really like the examples used in the work-text book. The daily problems lead the student into truly understanding the concepts and working with the concept from different directions. If you want your child to love math and know it from top to bottom, this is your curriculum. I've used it for several years and I have yet to see anything any better created.
Karen S on Feb 23, 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
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've taught middle school math grades 5-9 for 10 years and I've evaluated lots of curriculum. I've found the Math Mammoth is top notch!
Matt J on May 23, 2017
I have been using Math Mammoth texts for my elementary aged kids for the past year and a half and they are working great for us. Very straight forward, no need to plan, and each step prepares my kids for the next one very well. The methods teach new concepts step by step so no one gets lost or confused. Also, love the focus on mental math!
Abby B on Jan 10, 2017
I like the way the math mammoth curriculum is organized and the fact that it is mastery based.
Taneka A on Oct 25, 2016
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.

Good basic math curriculum for my reluctant math student
Kim K on Jun 22, 2016
We love the Math Mammoth curriculum and you can't beat this price!
Janna B on May 4, 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.

My son loves it!
My son is thriving in MM. He likes how Maria explains each of the concepts and the “why’s” in multiple ways. He also likes how it’s very cut and dry and to the point. He enjoys math. I like how It works through the concepts gradually and thoroughly that my son can work on it independently. You get a rigorous and complete math curriculum that works well and at an affordable price it’s a win,win in our homeschool.

Just Wonderful!
I can't rate Math Mammoth highly enough. My husband and I grew up learning math the traditional way and muddled our way through, but stll tend to find math and numbers confusing. I did not want that for our children, so I tried to find a better way To teach them about numbers.
I heard that Singapore taught math comprehension so much better and didn't kill your kids love of learning with endless repetion, so we took that route. However I found Singapore to have gaps that I, as a math-challenged teacher, could not fill in. I struggled and gave up many times. Because of this and other factors, my kids and I got years behind in math. :(
I just discovered Math Mammoth this last November, and it truly has been an answer to prayer. We went back to start near the beginning and are cruising through the workbooks and learning more quickly and easily than I would have thought possible! The concepts are clearly and carefully explained and the work is easy for the kids to complete on their own. The amount of repetition is reasonable but easy enough to cut out when not needed. And best of all, math concepts are taught from more than one approach,without being confusing, so the kids can understand things from more than one angle. Great educators deserve higher praise and renown than most other professions and Maria Miller is truly deserving of very high praise and appreciation! She has opened up a world of understanding when it comes to numbers! Thank you so much.
