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.

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.
clearwaters14 on Sep 13, 2020
Have used Math Mammoth in the past and we appreciate the colorful text that emphasizes mastery. Our daughter is using Saxon 3 and needs more time with the material before she is developmentally ready to move on to 4th grade level. We will use this text as a comprehensive (year-long) review of concepts she already knows. I recommend using the text both sequentially and as review. We usually reserve several problems from each section for later review.
Douglas H on Jul 24, 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
Like Math Mammoth, workbook is easier than having to print out the electronic pdfs
Colleen V on May 26, 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
sale and we enjoy this program.
Angelique M on Sep 22, 2019
We used the worksheets for grade 2 and wanted to try the entire curriculum for grade 3.
Anna B on Apr 23, 2019
For the same reasons I mentioned for 3-A Worktext. I felt the price was reasonable enough to order 3-B without trying the program first.
Deb T on Oct 19, 2018
I ordered this for my daughter in law as she home schools and this is what she wanted.

School required curriculum.
Tracy R on Jul 2, 2017
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.

Are there any sample pages of Math Mammoth so I can see what it looks like?
A shopper on Mar 26, 2019
BEST ANSWER: I found a website that offers sample pages and worksheets. But i cant share the link in here. If you Google Math Mammoth practicd sheets it should pull up a site directly from Math Mammoth itself.
Also I have used Math Mammoth for 2 years as a homeschool mom and personally love the work text books they give a brief lesson we can go over then offer lots of practice.
