Skills Review Workbook

cover for Math Mammoth Grade 5 Skills Review Workbook

This workbook is supplemental, and provides additional practice for the topics in the curriculum. I recommend you only purchase it once you are sure the student does need supplemental practice. Learn more.

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 (if they can read) to teach themselves and to learn directly from the books.

You will also get separate answer keys, chapter tests, additional cumulative revisions (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.

This curriculum is essentially the same as the U.S. version of Math Mammoth Grade 5, only customized for the Canadian audience in these aspects:

  • The curriculum uses the metric measurement units. Since Canadians do use imperial units, such as inches and pounds, in some contexts, the curriculum does mention them, but not often. For example, the worktext 5-B contains an optional lesson on measuring in inches.
  • The spelling conforms mostly to American English, taking into account a few key differences where Canadian English follows British English.
  • Numbers are formatted with a space as a thousands separator, and a point as a decimal separator.
  • Page (paper) size is Letter.

The US version of the curriculum is aligned to the Common Core Standards, which means this curriculum may not be properly aligned to the fifth grade standards in your province. In fact, it is likely to align better with typical 6th grade topics in Canada. However, you can probably find material for any missing topics in neighbouring grades, which means you can simply re-order the material to solve most incompatibilities between different standards.


  • 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 math and number sense.
  • It requires very little teacher preparation, which is a big help to most parents. :)
  • 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 download version

  • 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 download version 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 table of contents for 5-A and 5-B (in the sample files), which will let you see the topics covered in more detail.

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.


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 the coordinate grid, line graphs, and average. 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).


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

  1. A ruler that measures in centimeters (for 5-B).
  2. A compass and protractor (for 5-B).
  3. A ruler that measures in inches (optional; for 5-B).
  4. 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 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.

Note: The grades 4-7 bundle currently includes the Canadian version for grades 4-6, and the U.S. version for grade 7. We decided to offer this bundle prior to us publishing the grade 7 CA version, so that people can get the discount when purchasing a bundle.

The main possible issue is that the U.S. version of grade 7 uses customary units (inches, feet, miles, pounds, gallons) in several places. However, since Canadians are typically familiar with these, it will probably not pose a big problem.

By having purchased this bundle, you can get the CA version of grade 7 for free once it is published (please contact us for it).

By purchasing any of the books, permission IS granted for the purchaser (teacher or parent) to reproduce this material to be used with his/her students in a teaching situation; not for commercial resale. Please note: you are not permitted to share the material with other teachers or parents.

In other words, you are permitted to make copies for the students/children you are teaching, but not for other teachers' usage.
