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 US version of Math Mammoth Grade 3, only customised for the international audience in these aspects:
- The currency used in the money chapters in grades 1-3 is the Australian dollar. (The download
versions for these grades also include the chapter on money for US, British, European, South African, Canadian, and New Zealand currencies.)
- The curriculum teaches the metric measurement units. Imperial units, such as inches and pounds,
are not used.
- The spelling conforms to British international standards (British English).
- Page (paper) size is A4.
- Large numbers are formatted with a space as the thousands separator (such as 12 394). (The decimals are formatted with a decimal point, as is used in the US version.)
The US version of the curriculum is aligned to the Common Core Standards, which means this curriculum may not be properly aligned to the third grade standards in your country. 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 maths 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.
- For multiplication tables and division facts, you can use our online practice program (free). Visit the pages for Multiplication Tables Online Practice and Division Facts Online Practice
Additional features for the download version
- The wortexts use Australian currency, but the chapter on money (chapter 5) is additionally provided in six other currencies: US, British, European, Canadian, New Zealand and South African. You will automatically get all these versions when you buy the digital version of Grade 3 Curriculum (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 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
Third grade is a time for learning and mastering two (mostly new) operations: multiplication and division within 0-100. 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:
- 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.
- 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).
- 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).
- 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).
Additional topics we study are time (chapter 4), money (chapter 5), measurement (chapter 8), and bar graphs and
pictographs (in various chapters).
Please also see the table of contents for 3-A and 3-B worktexts in the sample file, which will let you see a detailed list of the topics covered.
Here is a list of manipulatives that are needed or recommended for grade 3. Measuring tapes, scales, and measuring cups are only used in the measuring chapter.
- An old-fashioned alarm clock or other analog clock where you can turn the minute hand and the hour hand will turn as it is supposed to (optional; for 3-A).
- A ruler that measures in centimetres (for 3-B).
- A measuring tape that measures in metres (for 3-B).
- A kitchen scale that measures in grams (for 3-B).
- A measuring cup that measures in millilitres (for 3-B).
- 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 3-B).
Reviews / Testimonials of the 3rd grade curriculum
Maria, I wanted to thank you for such a wonderfully effective and affordable math curriculum. Last year, I used the light blue series with my 3rd grader in our first and only year of homeschool. This year, she returned to public school and was ranked in the 88th percentile on standardized beginning of the year math testing. What a relief to know Math Mammoth was what she needed to stay on grade level and in step with her peers! She’s come home on several occasions beaming with pride with her success in math at school. Many, many thanks from a grateful mom!!
Prior to using Math Mammoth, we had been using Teaching Textbooks for 2 years. Sad to say that those two years left my ten year old pretty behind. I looked at several different programs, but ultimately chose Math Mammoth (MM). The cost was the final tie breaker between this and Singapore. It's been wonderful! I really like the mastery approach as opposed to the spiral approach of Teaching Textbooks (TT). We came from grade 4 from TT but decided to start at grade 3 in MM to relay the foundation for my son and I'm glad we did. It's easily understood(for me), the concepts are easy to teach, and I appreciate the links at the beginning of each chapter for further practice. There were a few sites with games to learn the Roman numerals that really helped us both! Math is not my strong area but we both enjoy this curriculum and there is zero fight to do math every day. I'm honestly feeling more confident in my teaching abilities after using this curriculum for a few months, because it's helping me to better understand certain math concepts as well. I recommend it in any homeschool Facebook group I'm in, whereas I used to recommend TT, because hey, who doesn t love being able to say, "Go do your math!" and let the computer do the work for you? Definitely learned that one the hard way.

Math Mammoth has been very inviting for my son - it provides a lot of guidance on how to do a problem using mental math methods. It provides grids that he can use, which help him know when he should/could write the problem down and show his regrouping work. It eventually weans the kids off of these grids. My son now feels comfortable with the methods, and will tackle a problem mentally if possible, but will readily write it down if necessary. Another advantage is that all of the instruction and worksheets are included in the text. I appreciate that all of the grade levels are included for a very economical price. I ordered this program at the end of our 3rd quarter of 3rd grade, and I have been having my son move quickly through the 3rd grade work to touch on areas where he was weak or cover material he has missed. This leaves us in a good position to start off 4th grade next year. I'll be having my 2nd grader use this program next year as well, and we are looking forward to it!
Math Mammoth is working out great for my kids, and me. It isn't as complicated to teach/prep as some other curricula we've tried (Singapore and Saxon), but I really feel it covers everything really well. Kids don't mind doing the worksheets... they mix it up so it doesn't get too boring and tedious. We did the 3rd grade program this year for my at level daughter and 1st grade advanced son. I don't make him do quite as many problems (my 3rd grader does them all) since he has the ability, but not really the patience to do as many. We plan on using the 4th grade program next school year. Buying it through the co-op is an amazing value for such a great program.

...it is the perfect blend of easy and challenging for Mr. C.
It's easy to understand but the lessons still give him a real challenge.
In one lesson Mr. C was working on mental addition of 2 and 3 digit numbers and he loved challenging himself to get the answers quicker and quicker. While some curriculums might simply say "do the problem in your head", Math Mammoth broke the lesson down step by step to give Mr. C different tips and tricks to solve mental addition in easier ways.

I spent quite a bit of time researching which Math curriculum to use when I started homeschooling my 3rd and 5th grade kids. This was exactly what I hoped to find when I went looking. The placement test helped confirm which level to use. The material is easy to understand, yet challenging. We all love it and will continue to use it!
Thank you for creating Mammoth Math! It is beautifully and incrementally organized to promote student learning, makes the kids think, has excellent problem solving throughout, and follows the Common Core better than most curricula. All this for a superb price, especially since teachers pay for much of what is provided in their classrooms!
