Includes part A and B worktexts, answer keys, tests, mixed revisions, a worksheet maker, and Soft-Pak.

You will be purchasing the download from my authorized reseller Comecero, LLC.

At the heart of the curriculum are two student worktexts (A and B), each covering about half a year of maths work. These worktexts contain all the instruction and the exercises in the same book — which makes lesson preparation a breeze. The worktexts are written directly to the student, and thus they allow many children to teach themselves and to learn directly from the books.

You will also get separate answer keys, chapter tests, additional cumulative reviews (I do recommend you use at least some of them), and a versatile worksheet maker (Internet access required) for those times when your child needs just a bit more practice.


  • Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the maths, not just learn "HOW" to do it.
  • Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired.
  • The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much.
  • There is a strong emphasis on mental maths and number sense.
  • Very little teacher preparation is required. :)
  • The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material.
  • After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice.

Additional features for the digital version (download)

  • The PDF files can be filled in on a computer, phone, or tablet, using the annotation tools found in many PDF apps. Learn more.
  • BONUS! The digital download also comes with BONUS Soft-Pak programs. The 6 programs in Soft-Pak (4 math, 1 language arts, 1 list maker) offer both on-screen and printable activities in a low-graphic, high content format. Read more and see screenshots.

Overview of topics

The main areas of study in Math Mammoth Grade 5 are:

  • the four operations with whole numbers
  • place value with large numbers and the judicious use of calculator
  • problem solving & simple equations
  • decimal arithmetic (all operations with decimals)
  • statistics and graphing
  • fraction arithmetic (all operations with fractions)
  • geometry: review of angles, area, and perimeter; drawing circles; classifying triangles & quadrilaterals; volume of rectangular prisms

Please also see the tables of contents in the sample file, which will let you see the topics covered in more detail.


The fifth grade is time for fractions and decimals, in particular. We study fractions and decimals and operations with them in depth and with substantial detail. Students also deepen their understanding of whole numbers, learn much more problem solving, and get introduced to the calculator.

The year starts out with a study of whole numbers and their operations. Students get to review multi-digit multiplication and learn long division with two-digit divisors. We also review divisibility and factors from fourth grade, and study prime factorization.

In the second chapter, the focus is on large numbers and using a calculator. This is the first time a calculator is introduced in Math Mammoth complete curriculum—thus far, all calculations have been done mentally, or with paper and pencil. I want students to learn to be critical in their use of the calculator and use it with good judgment. Every exercise where calculator use is to be allowed is marked with a little calculator symbol.

The third chapter is about equations and problem solving. We study simple equations with the help of a balance and bar models. The main idea is to get students used to the idea of an equation and what it means to solve an equation. Students also do a fair amount of problem solving using the visual bar model.

The fourth chapter is about decimals and some of the operations with decimals (the rest will be studied in chapter 6). Fifth grade is the time when students learn all the basic operations with decimals. In this chapter, we focus on place value with decimals, addition and subtraction of decimals, and multiplication and division of decimals by whole numbers. Multiplying decimals by decimals and dividing decimals by decimals is covered in chapter 6.

In chapter 5 we study graphing in a coordinate grid, line and bar graphs, and average and mode. Today's world has become increasingly complex with lots of data presented in the media, so our children need a good grasp of statistical graphs to be able to make sense of all of that information.

Chapter 6 continues our study of decimals. The focus is on multiplying decimals by decimals, dividing decimals by decimals, and conversions between measuring units.

Chapter 7 covers the addition and subtraction of fractions — another topic of focus for 5th grade, besides decimals. The most difficult topic of this chapter is adding and subtracting unlike fractions, which is done by first converting them to equivalent fractions with a common denominator.

In chapter 8, we study the multiplication and division of fractions from various angles.

Chapter 9 takes us to geometry, starting with a review of angles and polygons. From there, students will learn to draw circles, to classify triangles and quadrilaterals, and the concept of volume in the context of right rectangular prisms (boxes).

South Africa

Math Mammoth South African Version has been customised to South Africa in the following manners:

  • The names used are South African names (such as Ansie and Jali).
  • The currency used in word problems is rand. The money chapter teaches both rand and cents.
  • The material is "all metric". In other words, the US customary measuring units are not used.
  • Spelling is British English instead of American English.
  • Paper size is A4.
  • Geographic locations used emphasise South African locations (such as Pretoria, Johannesburg).

Please note that the curriculum is not following the South African official syllabus for 4th grade maths. Instead, it simply is a copy of the US version of Math Mammoth Grade 4. For the most part, Math Mammoth exceeds South African standards. Some standards may not be covered.

Skills Review Workbook

Math Mammoth Skills Review Workbook, Grade 5 provides additional practice for the topics in Math Mammoth Grade 5 curriculum. I recommend you only purchase it once you are sure your student does need supplemental practice. Learn more.


Here is a list of manipulatives that are needed or recommended for grade 5.

  1. A ruler that measures in centimetres (for 5-B).
  2. A compass and protractor (for 5-B).
  3. Fraction manipulatives. The curriculum contains printables to make your own fraction manipulatives. The text uses visual pie models extensively, and students even learn to draw them for themselves for the exercises, therefore making or buying the manipulatives is entirely optional (optional; for 5-B).

Reviews & testimonials

Math Mammoth review at As They Grow Up blog

Just want to say thank you! I've been homeschooling for 9 years and I'm going to switch my youngest son (5th grade) to Math Mammoth from Singapore Primary Mathematics 2022. I think he will thrive on the text being addressed to the student rather than my attempts at scripted lessons because math is not my strong suit! I appreciate all the details on your website. I watched some of your teaching videos and my son will enjoy not being "babied" as he feels he is with videos we watched with Singapore. I can tell you are passionate about teaching math and providing excellent curriculum. THANK YOU!! Wish I had found you sooner!!

This is our first year homeschooling because we wanted to travel. We started doing Singapore Standard Edition because that is what she was doing at her former school. I immediately realize that despite an MBA and a pretty good math background, I had no idea what I should be doing to teach the lessons. So we stated looking for something else, challenging, but that I could understand and teach. We selected MM and also are using CTC Math because of the videos, a perfect combination. I like that MM is a printable since we do not always have internet connection on the road and they give us all the grades. Because Singapore skips some basics in the early grades, I am combining both the 4th and 5th grade MM lessons as I determine what my child needs. Excellent program, plenty of practice and the examples, unlike Singapore really make the lesson objective clear. I would highly recommend.

My children (first and fifth graders) have both enjoyed Math Mammoth very much. I like that I only print what I need and they like not being bombarded with too many problems per concept. Once they get it, we move on. I love the unit studies like "Money" which I can use with both kids. Highly recommend Math Mammoth!

Thank you so much Maria. We adore you! I really appreciate having access to such an exceptional program. What a God send. You are such a blessing to our family and our homeschooling community. It's the best math program we've seen. And we've tried many over the years.... Saxon, Singapore, Calvert and one in the public school system that we were able to borrow. It beats them hands down. It is thorough, well thought out and it makes our kids think math. There's just enough practice and repetition for concepts to really sink in without boring them. It's the only math program that we've used that I didn't have to run searching for a supplement. Thanks again Maria, so very glad that we found you.

Zayne's math studies are going great! I like this curriculum so much better than Saxon... we spend enough time on each new concept so that he really "gets it"! The downloaded material (grade 5) is much more colorful (and therefore keeps his interest!) than the printed version of Math Mammoth [used in grade 4]. And with all the extra "helps" you provide; from hints, suggestions and games to a list of other sites with games, downloads (math rider was a favorite!) and freebie helps... you've made math FUN for BOTH of us! I really can't thank you enough (and I've already homeschooled 2 boys...one is a computer website developer and the other is a chemical engineer...so I'm an OLD mom and frankly ready for some fun with schooling)!

Math Mammoth is AWESOME!

I am a mother of 2 lovely daughters ages 13 and 11, both in French immersion public school on Vancouver Island, Canada.

My youngest daughter has had a difficult Grade 5 year with math and had some extra learning assistance provided at school. I have often worried that because all instruction is in French, her second language, it may ultimately be more difficult for her to understand the math lessons or perhaps the way it was taught. And although I have tried to help her during the school year, it became more of an exercise in translation, for I have only taken 1 year of basic Introductory French at University, and she had to translate the question for me before I could help.

I knew that we needed to work on this over the summer. I learned that there were more gaps in her math knowledge than I previously believed. This is when I abandoned tutoring her math in French, and began looking for worksheets on the internet. I was very happy to come across your free worksheets but after looking at the complete Mammoth worktext sample pages and the Youtube clips to help teach the 'teacher', I was so impressed, I bought the Grade 5 Light Blue worktext A and B. I really like how clearly the lessons are explained and how the concepts flow together seamlessly and that you personalized this course with instruction for the 'teachers'. And when I told my daughter that I found a math teacher on the internet that can teach ME how to teach, she seemed pleased and perhaps a little relieved (!!? )

So here we are, day 4, page 17, she is picking up speed and her attitude has lifted as she begins to understand math covered so far. I really like the the lessons or rules are highlighted or outlined so it is easier to refer back to. The worksheet are visually appealling as well. I hope we can get through the whole course this summer without it being too arduous, but I see that she is gaining self esteem and excitement she works though questions with a little less guidance from me.

So, Thankyou very much Maria!

I expect to be purchasing the grade 6 Light Blue worktext to 'work along' with her as she returns to Math in grade 6 French immersion in September. I feel more confident that I will be able to track her progress and then offer help as necessary (or IF necessary!).

Sincerely, Elaine
