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.


Features

  • Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, 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.
  • It requires very little teacher preparation. :)
  • 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.

Overview of topics

In the fourth grade, students focus on multi-digit multiplication and division, learning to use bigger numbers, solving multi-step word problems that involve several operations, and they get started in studying fractions and decimals. This is of course accompanied by studies in geometry and measuring.

The year starts out with a revision of addition and subtraction, patterns, and graphs. We illustrate word problems with bar diagrams and study finding missing addends, which teaches algebraic thinking. Children also learn addition and subtraction terminology, the order of operations, and statistical graphs.

Next come large numbers—up to millions, and the place value concept. At first the student revisions thousands and some mental maths with them. Next are presented numbers up to one million, calculations with them, the concept of place value and comparing. In the end of the chapter we find out more about millions and an introduction to multiples of 10, 100, and 1000.

The third chapter is all about multiplication. After briefly revising the concept and the times tables, the focus is on learning multi-digit multiplication (multiplication algorithm). The children also learn why it works when they multiply in parts. We also study the order of operations again, touch on proportional reasoning, and do more money and change related word problems.

The last chapter in part A is about time, temperature, length, weight, and volume. Students will learn to solve more complex problems using various measuring units and to convert between measuring units.

In part B, we first study division. The focus is on learning long division and using division in word problems. In geometry, we first revise area and perimeter, and then concentrate on the topic of angles. Students measure and draw angles, solve simple angle problems, and classify triangles according to their angles. They also study parallel and perpendicular lines.

Fractions and decimals are presented last in the school year. These two chapters practice only some of the basic operations with fractions and decimals. The focus is still on conceptual understanding and on building a good foundation towards 5th grade math, where fractions and decimals will be in focus.

When you use these books as your only or main mathematics curriculum, they can be like a "framework," but you do have some liberty in organizing the study schedule. Chapters 1, 2, and 3 should be studied in this order, but you can be flexible with chapters 4 (Time and Measuring) and 6 (Geometry) and schedule them somewhat earlier or later if you so wish. Chapter 3 (Multiplication) needs to be studied before long division in Chapter 5. Many topics from chapters 7 and 8 (Fractions and Decimals) can also be studied earlier in the school year; however finding parts with division should naturally be studied only after mastering division.

Please also see the tables of contents for 4-A and 4-B in the sample, which will let you see the topics covered in more detail.

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 4 provides additional practice for the topics in Math Mammoth Grade 4 curriculum. I recommend you only purchase it once you are sure the student does need supplemental practice. Learn more.


Manipulatives

Here is a list of manipulatives that are needed or recommended for grade 4. Measuring tapes are only used in the measuring chapter.

  1. A protractor (for 4-B).
  2. A ruler that measures in centimetres (for 4-A and 4-B).
  3. A measuring tape that measures in metres (for 4-A).
  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 for themselves for the exercises, therefore making or buying the manipulatives is entirely optional (optional; for 4-B).

Review of Math Mammoth by mommybugg238

Review of Math Mammoth from You've Got This Math (focusing on MM grade 4)

Hi Maria, I'm writing to thank you for Mammoth Math, Grade 4! I realized in November that my fifth grader had learned virtually no math in her fourth grade year, when her school was mostly remote due to COVID. The COVID learning loss is real, and a lot of the concepts in fourth grade math, like problem solving, time and measurement, and beginning to develop a sense of fractions and decimals, just can't be skipped over. We did two pages a night, about six nights a week, plus two pages in the morning on most weekends and holidays. It took us a little under six months to complete the Level 4 Light Blue Series, and I'm thrilled to let you know that my daughter has mastered the material. We are going on to Level 5, and I expect she'll be fully caught up and ready to go just as she starts sixth grade. Thank you for creating such a high-quality and simple-to-use math curriculum!!

I just wanted to say that my kids and I are really enjoying the curriculum. They are finishing up the 4th grade (light blue) course right now. I love how everything is broken down. Things are really clicking for my twins. I have one child that picks up on concepts rather quickly, and one for whom academics are always a struggle. Well, several times throughout the year I've heard her say, "I actually get this." You have no idea how happy that makes me. I'm glad I decided to purchase the bundle, so the next few years of math are covered.Thank you.

Just finishing Chapter 2 of Math Mammoth 4th grade. Love the open and go format. So many extras are included in the bundle--reviews, additional problems to work, websites for fun practice on each topic. Really well-designed curriculum.

Also, prior to buying we had our kids do placement tests with Math Mammoth and an online curriculum with a comic book-based text. They were in tears and very resistant, but they love Math Mammoth!"

I just wanted to tell you that I just moved my son from Horizons math to your Math Mammoth. Mostly because I wanted a mastery-type curriculum and yours was highly rated and also suggested by Math Without Borders. He is doing so well with it and it's hard to believe that just after a few weeks his mental math has improved incredibly. He loves the workbook and the games are excellent and has been a great motivator for him. Engineering is in his future so I wanted to hit math hard this year to prepare him for Math without Borders.

Thank you so much for all of your emails and care taken with your curriculum. He will be getting a Mammoth stuffed animal for Christmas!!

Regards
A happy homeschooling mom (Allisha)


"Math Mammoth utilizes color in their books. This is a HUGE bonus in my opinion. It can be very monotonous to stare at page after page of black and white numbers, especially for little ones. Things like the fractions you see here are so much more interesting, and easier to explain when you have color designations."

New to home schooling, I felt overwhelmed trying to pick out a suitable curriculum to suit a 1st and 4th grader (in particular), having come through regular school up to 3rd grade. Both kids are enjoying Math Mammoth so far. The hints and tips for mental math throughout are great. The program provides flexibility if a student is struggling on something because I can hop back and print out some 3rd grade reminders of key concepts. I love that I can generate extra worksheets of different problems online anytime - brilliant. We haven't got far enough yet to use the chapter reviews but glad that they are there for us when we're ready. The pricing through homebuyers is amazing to cover both students through 8th grade if we so choose. I chose to do the download option and print as we go. I would recommend this product (and a good printer!)."
