Product Description:

Third grade is a time for learning and mastering two (mostly new) operations: multiplication and division within 100. The student also deepens his understanding of addition and subtraction, and uses those in many different contexts, such as with money, time, and geometry.

The main areas of study in Math Mammoth Grade 3 are:

  1. Students develop an understanding of multiplication and division of whole numbers through problems involving equal-sized groups, arrays, and area models. They learn the relationship between multiplication and division, and solve many word problems involving multiplication and division (chapters 2, 3, and 9). They learn the multiplication tables, and learn how to use their knowledge of multiplication tables to solve basic division facts.
  2. Students develop an understanding of fractions, beginning with unit fractions. They use fractions along with visual fraction models and on a number line. They also compare fractions by using visual fraction models and strategies based on noticing equal numerators or denominators (chapter 10).
  3. Students learn the concepts of area and perimeter. They relate area to multiplication and to addition, recognize perimeter as a linear measure (in contrast with area), and solve problems involving area and perimeter (chapter 7).
  4. Students fluently add and subtract within 1,000, both mentally and in columns (with regrouping). They learn to add and subtract 4-digit numbers, and use addition and subtraction in problem solving (chapters 1 and 6).
  5. Additional topics we study are time (chapter 4), money (chapter 5), measuring (chapter 8), and bar graphs and pictographs (in various chapters).

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.

Have been using Math Mammoth for 5 kids over 10years. Use to print at home, but this is much more convenient.
Tina T on Dec 6, 2021
I'm using The Good and the Beautiful math for its games, but I love Math Mammoth for how thorough it is, and how my daughter can plow through it without much help. I'm sure we won't do every page, but it'll be perfect for the days I don't have time to do all the games and activities in TGATB.

Great math curriculum. We have the downloads but it's too expensive to print them at our local print store. We enjoy this math tremendously and have seen great results.

Math Mammoth is a cheap and easy program. I like how it is open-and-go and has all the information you need to teach right there on the student page.
Laura M on Aug 28, 2020
good straight-forward math curriculum with little parent involvement
Susan V on Aug 19, 2020
We initially bought this in black and white and found it to be too bland and visually flat. The colored version helps give better spacial awareness and I can tell them to pick a problem in the green box for example.
Jessica L on Jul 22, 2020
We have been using this curriculum for all four of our kids. It is thorough with multiple approaches per concept.
Deborah S on May 28, 2020
Used this with my older son so I'm both familiar and feel it's a great curriculum. It shows you how to do things in many different ways so that a child can understand the WHY and then choose HOW to compute.
Anna B on May 27, 2020
We've really enjoyed the curriculum thus far. Easy to follow and teach.
Stephanie G on Apr 27, 2020
I am a professor of mathematics, and we have been through several curricula for our homeschooled children, some with special needs. We settled on this approach, because it is comprehensive, pedagogically sound, even correlated with the Core Curriculum Standards (though that is not a huge consideration with us). Homeschool friendly with appropriate ancillary materials. And not super-expensive.
Barry P on Mar 24, 2020
My 9th grader has completed the entire Math Mammoth series (grade 3-7). I am very happy with his depth of understanding. He was well prepared for Foerester Algebra. I have ordered Math Mammoth again for my younger students.

Cynthia D on Jul 25, 2019
Math Mammoth was a breakthrough for us when my daughter was in 3rd grade. The explanations in the worktext are so easy to understand, and I have now switched both children to Math Mammoth!
Hope S on Jun 4, 2019
Math Mammoth was a great fit for my son in grades 1 and 2. I look forward to teaching it again!
Elsa E on May 15, 2019
We used the worksheets for grade 2 and wanted to try the entire curriculum for grade 3.

So far this has been the best math choice for us. It's written to the student making it easy for me to teach.
User on Dec 20, 2018
I have been extremely impressed with Math Mammoth. It has, as does everything, some things that I would change but all in all it is so very well ordered and thought out and simple. Also it is inexpensive and I do very much appreciate that.
Kathleen B on Oct 25, 2018
Seemed to offer math strategies for a highly intelligent child with dyslexia for whom math facts may be difficult to memorize even though he is already grasping higher math concepts. Also, dyslexic individuals are highly visual and grayscale math books have not been stimulating enough.
Deb T on Oct 19, 2018
I ordered this for my daughter in law as she home schools and this is what she wanted.
Nancy C on Sep 18, 2018
This is our second year using Math Mammoth and our fourth year homeschooling. We love how Math Mammoth teaches mastery before moving on to the next concept.
Crystal C on Aug 12, 2018
After review it seems the best for my students.
Susan S on Feb 23, 2018
We used the blue series last year to pick and choose which topics to cover. I decided to use the light blue series this year so we can follow the progression laid out for us. I like the way Math Mammoth combines instruction and practice in one worktext, and the mastery approach works well with the right amount of review for us.

Carmen L on Jul 14, 2017
School required curriculum.
Tracy R on Jul 2, 2017
My child has been using Right Start Math, but is ready to begin working independently from me, and this is my favorite curriculum for that purpose! The joint emphasis on critical thinking, on understanding the mathematical concepts, and on mental arithmetic make this a winner for me! This will be my second child in this curriculum, and I'm so pleased with it, I don't even look for alternatives from year to year. <br /><br />My children definitely prefer the colored text over the black and white workbook.
Katherine W on Jun 16, 2017
It got a great review on Cathy Duffy's 102 Homeschool Picks, and it meets my criteria of minimal teacher prep time, teaches concepts as well as drill, and goes beyond common core. I also like that supplemental worksheets are available on the Math Mammoth website, and to top it off, it's a good deal!
Julie B on Sep 16, 2016
Our daughter has extremely strong reasoning and number sense skills, which I believe is due in part to using the Mammoth Math materials. I am looking forward to teaching her this year, using this workbook. Previously I have bought the downloadable version and have had the worktexts printed and bound at our local copy centre. It works out to be the same price to buy these worktexts already printed andin COLOUR! Our daughter is excited about having them in colour in this year.
Karyn H on Sep 9, 2016
The descriptions are clear and right in the book so you just need to buy the workbook no teacher's book. There is lots of review of previous chapters as you complete each one so you keep building and maintaining your skills. It's the most cost effective complete math curriculum that I've found that works.
Melanie W on Aug 9, 2016
This is our 3rd year using Math Mammoth! We love it!
Rochelle W on Mar 15, 2016
This math curriculum has worked well for our family. It is a great balance of mastery and review. I like the length of the lessons as well. Very doable for younger students to sit and complete in a timely manner.
jennifer w on Mar 15, 2016
Recently finished Math Mammoth Grade 2. Curriculum is straightforward, doesnâ??t talk down to children, and can be worked independently once concepts are reviewed with teacher/parent. It works best for my children.
Jessica H on Feb 16, 2016
I love Math Mammoth. My son has dyscalculia, and we struggled to find just the right curriculum for him, but this is it!! A couple weeks ago he said, "Mom, remember when math was so hard for me?" This curriculum has allowed him to achieve success and gain real confidence!

switching from Singapore math, how do I determine which grade for my child? (is it as challenging as Singapore math or on a different level... would grade 3 be comparable across programs?)
Sarah on Mar 3, 2023
BEST ANSWER: Math Mammoth is challenging, but it depends on how your student learns. I have a mathematically inclined child that excelled with this curriculum. I switched from Math Mammoth to Singapore with a different child because Singapore is more hands on and visual for that learner. I would look at the table of contents, as Singapore does introduce some concepts in earlier grades than Math Mammoth. The Math Mammoth website has samples you can download if you want to see a more robust sample. A random side note - my math loving child performed better when the books were in color, than when I purchased the black and white version. I mention that because there are some editions of Singapore in color, and others in black and white.
Are these book coil bound?
A shopper on May 25, 2022
BEST ANSWER: No. They have a glued spine. The lay open flat and aren't very thick, so they're easy to write in. They're also available in PDF on the math mammoth website so you can downloand it and print unbound from home.
When you buy a Math mammoth worktext on its own (not as part of a package), is there an answer key in the back?
A shopper on Jun 27, 2016
BEST ANSWER: No, there is not. The answer key is a separate publication and covers both the A & B books of each level.

The RR catalog description of 'Creativity Express' was extremely thorough so I hesitate to add to it I think my review may be helpful for a different aspect of purchasing so I continue I purchased this art instruction CD-ROM because of homeschool mom guilt Am I giving the kids all the classes they would enjoy in a 'regular school?' Are they 'missing out' because they aren't getting art instruction by a professional artist? This was compounded by the fact that my six year old son seems to get a great deal of enjoyment from drawing- technical drawings of planes etc but also figures My basic drawing skills were about exhausted on him already and we can't afford art lessons So I turned to RR to see what they had I figured $25 was a decent price and I hoped that I wouldn't be annoyed by a penguin and a polar bear discussing art I was greatly pleased My kids aren't allowed to watch tv when they wake up so now when I come out for my coffee they are on the computer learning about art When I am in the kitchen preparing dinner I am learning from just overhearing their lessons The characters are not annoying or repetitive the 'classes' are easily selected and navigated and the skills are easily practiced on paper They learn alot of art history and interesting facts and usable skills for their own art projects The lessons have come up in the car and at bedtime so I can tell that they are interesting and informative enough to stick in their little brains past the time on the computer The 6 and 8 year olds are 'doing' the lessons and the 3 year old is sitting beside them laughing and learning as well My homeschool mom guilt has evaporated-- my son taught me about hot and cool colors! He's not missing out on anything! I think this CD-ROM is great for a number of uses-- you could monitor your child and ensure that they do each lesson such as one a week and you'd get about a year of lessons You could just let them do art lessons on the 'give-it-up days' that we all have You could let them use it instead of playing mindless games on the computer It could be a summer class to keep them thinking I am really glad that I purchased this product and my kids say that it is "really cool and fun and funny"

What a fantastic product! I didn't think I could get my non-artistic son interested in any kind of art instruction but this has changed everything for him He has gone from grumbling and complaining about art lessons to begging to be able to use this CD ROM He regularly wants to try the actual hands-on projects after the lessons and our whole family has benefited from the art history facts that he now throws out from time to time All I had to do to get him started was load the cd and show him how to use itwhich has been important since I'm also homeschooling a middle schooler (who also likes to go through the lessons with her brother) and caring for a newborn For roughly $30 this was a great purchase for our family and our homeschool!
