Singapore Math (Dimensions Math) vs Math Mammoth: which one suits your child?
Both teach math for understanding with bar models and mental math, but Singapore Math is taught by the parent from a guide, while Math Mammoth explains each lesson on the page so many children can work alone.
The short answer. Neither is better for every child. Choose Singapore Math (Dimensions Math) if you want to teach math yourself and enjoy leading a short discussion each day. Choose Math Mammoth if your child reads well and likes working through pages on their own. Whichever you pick, the level matters more than the brand, so find out where your child is before you buy.

How they differ
| Singapore Math (Dimensions Math) | Math Mammoth | |
|---|---|---|
| How a lesson runs | Parent leads a discussion of an opening problem (Think), then the textbook shows solutions (Learn), then the child practices in the textbook and a separate workbook. | The child reads a worktext page that explains the idea, works the problems on the same page, and the parent checks answers and sets the pace. |
| Parent role | High in the early grades: the textbooks are not meant to stand alone, and the lesson presentation sits in the Home Instructor's Guide. | Low to medium: no separate teacher's manual, short teaching notes per chapter, full answer keys; the parent steps in when a concept or word problem stalls. |
| Review (spiral or mastery) | Mastery by chapter; workbook practice mixes in earlier topics, with optional chapter and cumulative tests sold separately for grades 1-5. | Mastery by chapter with a mixed review at the end of each chapter and separate cumulative reviews; optional Skills Review Workbooks add spiral practice. |
| Visuals or manipulatives | Concrete to pictorial to abstract: linking cubes, base ten blocks and play money in early lessons, full color textbooks, black-and-white workbooks. | Mostly drawn visual models on the page rather than physical manipulatives; black-and-white pages that some children find plain. |
| Word problems | Multi-step word problems solved with bar models, a signature of the method; problems get demanding quickly. | Also uses bar diagrams; from grade 2 most word problems need two or more steps and pull in earlier topics. |
| Screen time | None required; optional paid lesson videos for grades 1-6. | None required; free videos match many lessons, plus optional online practice and games. |
| Pace against school grades | Publisher describes it as more advanced than typical US standards, often covering topics earlier; grades PK to 8. | Publisher says it meets or exceeds Common Core and warns many programs are easier; grades K to 8. |

Switching between Singapore Math (Dimensions Math) and Math Mammoth
From Singapore Math (Dimensions Math) to Math Mammoth
Take the Math Mammoth placement test, which is an end-of-year test for each grade. Children coming from Singapore Math usually place close to their Singapore level because the two programs teach in a similar way; check statistics and probability, which Math Mammoth covers more fully. Expect an adjustment period while the child learns to read explanations without the parent leading.
From Math Mammoth to Singapore Math (Dimensions Math)
Take the Singapore Math placement test for the half level you think the child has finished; passing it means move on, not start there. Children switching in often start a half or full level below their grade, mostly because of mental math strategies and multi-step word problems. With few gaps, the publisher suggests borrowing material from the earlier level instead of going back a full year.

See where they stand →Questions parents ask
Is Math Mammoth the same as Singapore Math?
No. Both use bar models, mental math and a mastery approach, but Math Mammoth is written to the child in one worktext, while Singapore Math is taught by the parent from a separate guide.
Is Singapore Math harder than Math Mammoth?
Singapore Math introduces some topics earlier and its word problems are known for being demanding, but both programs run at or above typical US grade expectations. Children from gentler programs often place lower in either one.
Can my child do Math Mammoth or Singapore Math independently?
Many children can work through Math Mammoth largely on their own once they read well. Singapore Math is built around parent-led lessons, though older and quicker students can do more of the practice alone.
Which level should my child start in?
Use the publisher's placement guidance for the program you choose; levels rarely line up one to one between programs. If you are not sure where your child stands, an independent adaptive test such as Point of Progress (grades 3 to 10, about forty minutes at home) shows their level and the skills that need work.
