Short version Math Mammoth is a mastery-oriented homeschool math curriculum whose Light Blue Series covers grades K to 8 in two worktexts per grade, with explanations written directly to the student and a strong focus on mental math and word problems. A Math Mammoth tutor works live on the chapter where self-teaching has stalled. Modern Age Coders offers that help live online, mainly in its Elementary Mathematics course, choosing between a group batch and 1-on-1, and you pay nothing for the first class. Courses for Light Blue students ## Live math courses for Math Mammoth families The worktext stays your curriculum. These classes add a teacher who listens to how your child thinks.

The site says: "Math Mammoth Light Blue Series constitutes a full elementary mathematics curriculum for grades K-8." It also publishes topical books and versions for other countries. | Feature | What Math Mammoth says | | --- | --- | | Scope | Light Blue Series, kindergarten to grade 8 | | Approach | Mastery-oriented, organized into chapters by topic; "Each grade level typically contains 8-10 chapters." | | Emphasis | Conceptual understanding, mental math and number sense; "Visual models and exercises are used a lot." | | Mental math | "Mental math strategies are taught and practiced explicitly." | | Word problems | "Word problems are present in nearly every lesson", with operations varied so children have to think | | Teaching style | "All the instruction in the worktexts is written directly to the student."; described as nearly self-teaching | | Videos | Free videos matched to the curriculum for grades 1 to 7, with grade 8 in progress | | Other books | Blue Series topical worktexts for filling gaps or supplementing another curriculum | | Versions | US, International, Canadian and South African | ### What comes after grade 8 Math Mammoth is clear: "Math Mammoth does not offer algebra 1 or above." It adds: "After MM7 or MM8, students can proceed directly to high school math (such as algebra 1)." That handover is a natural moment for a live teacher, because the next curriculum will be written in a different voice. ### Why the operations are mixed The site explains that "The operations used in the problems vary so that children learn to think, and not simply apply the operation that is in the title of the lesson." That is excellent design, and it is also why some children stall: they can do the lesson's skill, but not yet decide when to use it.

There is no separate teacher script. "Each grade level consists of two student worktexts (A and B), which contain both the teaching (explanations) and all of the student work (exercises)." | Part | What it is for | | --- | --- | | Worktext A and worktext B | The explanations and the exercises, lesson by lesson, in chapters by topic | | Answer keys | Included for levels 1 to 8 | | Chapter tests | Included for levels 1 to 8 | | Cumulative review worksheets | Additional review across chapters, levels 1 to 8 | | Worksheet maker | Extra practice sheets, with internet access | | Videos | Matched to lessons, free online for grades 1 to 7 | ### Read Each lesson opens with an explanation and a picture, written to the child. Reading it slowly, aloud if needed, is the first step. ### Try Exercises follow straight after, beginning close to the example and moving further from it. ### Mix Word problems near the end use a mix of operations, which is where real understanding is tested. Because everything is in one book, a parent often sees only the finished page. The reasoning behind it may never be said aloud. Asking your child to explain one exercise each day, in their own words, is the simplest check that the self-teaching is working. Placement ## How do I place my child in Math Mammoth? Math Mammoth publishes free placement tests and gives unusually direct advice: "Many popular math curricula are easier than Math Mammoth and thus there is a danger the child is placed too high" if you go by grade alone. 1. **Know what the tests are.** Math Mammoth says "They are end-of-year (EOY) tests", meant to be taken after studying that grade. 2. **Start high.** Choose the highest level you think your child will pass, and give that test first. 3. **Read results by section.** The questions are grouped by topic, so a low geometry or fractions section shows exactly where a gap is. 4. **Test lower if needed.** Math Mammoth suggests giving sections of lower-level tests to find how large a gap is. 5. **Keep it low-pressure.** It advises against strict time limits, and suggests postponing tests for a child who is already anxious about math. ### Using the results with a tutor Bring the section scores to a free first class. A child who scored well overall but low in one topic does not need to drop a whole grade. Our teachers can work on that topic live while your child continues the main worktext, or you can use a Blue Series topical book for the same gap, as Math Mammoth suggests. ### Switching from another curriculum Children moving from a gentler program sometimes find Math Mammoth's word problems a shock. That is not failure; it is the placement warning in action. A few weeks of explained mixed problems usually settle it.

These are the places our teachers meet most often when homeschool students bring Math Mammoth work to class. They are general teaching guidance, not statistics. | Where | What happens | What tends to help | | --- | --- | --- | | Grade 2 and 3 mental math | Counts on fingers instead of using a strategy | Name one strategy and use only that for a week | | Grade 3 and 4 multiplication | Tables memorized in order, not by relationship | Build each fact from one you know | | Grade 4 long division | Loses place in the steps | Estimate first, then divide | | Grade 4 and 5 fractions | Treats numerator and denominator as separate numbers | Always draw the whole | | Making change | Subtracts on paper and loses track | Count up from the price | | Mixed word problems | Uses the operation in the lesson title | Ask "what is happening?" before any numbers | ### The self-teaching trap A capable reader can finish pages by copying the pattern of the example. Scores look fine until the chapter test or the cumulative review. If the review pages go badly after good lesson pages, the explanation was read but not understood. ### When to bring in a teacher Not for one bad page. A teacher helps when the same kind of mistake repeats over a chapter, or when your child stops wanting to open the book. Often a few sessions on one chapter are enough before the worktext can lead again. Worked examples ## What mental math strategies help with Math Mammoth? Math Mammoth teaches mental math explicitly, and these are the kinds of strategies our teachers practise aloud with students. All examples and wording are ours, not taken from the worktexts. | Fact | Strategy | Said aloud | | --- | --- | --- | | 7 x 8 | Double, double, double: 7 x 2 = 14, x 2 = 28, x 2 = 56 | "Times 8 is doubling three times." | | 9 x 6 | Ten times, minus one group: 60 - 6 = 54 | "Nine sixes are ten sixes take away one six." | | 6 x 7 | Five sevens plus one more: 35 + 7 = 42 | "Six groups is five groups and one more." | | 25 x 12 | Four 25s make 100: 12 is three fours, so 300 | "Group the 25s into hundreds." | | 4 x 19 | Round and fix: 4 x 20 = 80, minus 4 = 76 | "I used one too many in each group." | ### Dividing 96 by 4 in your head Split 96 into parts that divide easily: 80 and 16. Then 80 / 4 = 20 and 16 / 4 = 4, so 96 / 4 = 24. Check by multiplying: 24 x 4 = 96. The idea to say aloud: you may split the number you are dividing, as long as every part is shared by the same amount. ### Making change by counting up Our problem: something costs 13.65 dollars and you pay with a 20-dollar bill. Count up from the price: 35 cents makes 14.00, then 1 dollar makes 15.00, then 5 dollars makes 20.00. Change: 5 + 1 + 0.35 = 6.35 dollars. The idea to say aloud: it is easier to add up to the bill than to subtract across zeros. | Problem | What is happening, and the answer | | --- | --- | | A book has 8 chapters of 24 pages. How many pages? | Equal groups, so multiply [192] | | 84 stickers are shared by 7 children. How many each? | Equal sharing, so divide [12] | | A ticket costs 6.40 dollars; you pay 10 dollars. Change? | Count up [3.60 dollars] | | Sam read 37 pages, then 48 more. Pages read? | Joining, so add [85] | | A 3/4-full jug holds 600 mL. Full jug? | Each quarter is 200 mL [800 mL] | | 9 x 14 in your head | Ten fourteens minus one [126] | With a tutor ## How does a live tutor work alongside Math Mammoth? Math Mammoth is designed for independence, so a tutor should protect that. Our lessons follow the worktext and hand the work back to your child as soon as possible. 1. **Tell us the grade, worktext (A or B), chapter and lesson.** Placement test section scores help too. 2. **Read the explanation together.** The teacher asks your child to put it in their own words, which shows what was missed. 3. **Practise the strategy aloud.** Mental math in particular is learned by saying it, so classes are full of talk. 4. **Mix the problems.** Fresh mixed word problems written by our teachers, so your child practises choosing the operation. 5. **Hand back to the book.** When your child can explain the chapter, they carry on alone with the worktext and its reviews. ### Worktext alone For a child who reads the explanations, explains answers when asked and does well on chapter tests. ### Worktext plus a batch For a child who enjoys hearing others' strategies, in a class of fifteen to twenty. ### Worktext plus 1-on-1 For a gap shown by placement, or a chapter where confidence has gone. Strategies ## From counting to choosing a strategy Our description of how mental math grows in a Math Mammoth child. | Stage | What it looks like | | --- | --- | | 1. Counting | Counts on or uses fingers | | 2. Recalling | Knows some facts by heart | | 3. Deriving | Builds new facts from known ones | | 4. Choosing | Picks the quickest strategy and says why | ### For parents Stage 3 matters more than speed. A child who can build 7 x 8 from 7 x 4 will never truly forget it. Ask "how did you know?" more often than "what is the answer?" ### For students If you forget a fact, build it from one you know. Before a word problem, say what is happening in the story.

Yes. Homeschool students who use Math Mammoth join our teachers live online, working on the chapter where they are stuck. Classes run in a batch of 15 to 20 or one to one. ### What grades does Math Mammoth cover? The Light Blue Series is a full curriculum for kindergarten to grade 8. Math Mammoth says it does not offer Algebra 1 or above, and that after grade 7 or 8 students can go straight to high school math such as Algebra 1. ### Is Math Mammoth self-teaching? Math Mammoth describes it as nearly self-teaching, with all instruction written directly to the student and free matched videos for grades 1 to 7. Many children manage alone for long stretches; a teacher helps when a chapter does not click. ### How does Math Mammoth teach multiplication? Math Mammoth says mental math strategies are taught and practised explicitly. In our classes we build each fact from known ones, such as 7 x 8 by doubling three times, so children can recover a fact they forget. ### Where can I find Math Mammoth extra practice? Each grade includes a worksheet maker, and levels 1 to 8 include cumulative review worksheets; the site also offers free online practice. Our teachers add fresh mixed problems of their own in class. ### Which Math Mammoth placement test should my child take? Math Mammoth suggests starting with the highest level test you think your child will pass. The tests are end-of-year tests grouped by topic, so look at section scores, and test lower sections if a gap appears. ### Why is my child struggling with Math Mammoth word problems? In our experience it is usually because the operations are mixed on purpose, and the child is still using whatever the lesson title suggests. Asking what is happening in the story before using any numbers helps a lot. ### Will a tutor replace Math Mammoth? No. The worktext stays your curriculum. We teach the stuck chapter live and hand the work back to the book as soon as your child can explain it. ### When are classes? Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. ### Are you connected with Math Mammoth? No. We are an independent online school. Math Mammoth is a trademark of its owner, and we describe it only from its own published pages.
