Switching from Singapore Math to Math Mammoth: which level to check first
Find the last Singapore Math level your child worked in to see where to look in Math Mammoth, how strong the evidence is, and the free placement test to give next.
In short
No publisher we found publishes a direct Singapore Math to Math Mammoth crosswalk, so we place both programs on one shared grade scale from each publisher's own level guidance. Finishing 4A / 4B in Singapore Math points to Grade 5 in Math Mammoth, or Grade 4 if the placement test shows gaps (Confirmed by publisher). Evidence across all 6 Singapore Math levels: 6 Confirmed by publisher. The placement test is the real answer.
Checked Oct 17, 2026. Built from the same table as our math switch helper and methodology page.
The placement tests are end-of-grade tests, so they also show which specific topics are missing. Parents use them to check readiness for other programs too.

Why these levels
Singapore Math: Singapore Math says its levels align with U.S. grades and that students switching in often start at an earlier level. Sources: Singapore Math placement tests: levels align with U.S. grades; switching students often start earlier, Nicole the Math Lady placement examples (Abeka K to Singapore 1A; part of Saxon 2 to Singapore 2A).
Math Mammoth: Math Mammoth's Light Blue Series is organized by grade level, with a grade-level book and end-of-year placement test for each of grades 1 to 8. Sources: Math Mammoth Light Blue Series: complete curriculum by grade level, Math Mammoth placement tests for grades 1-8 (end-of-year tests).
A match is only as strong as its weaker side. Confirmed by publisher means both publishers state the level we used, not that they confirmed the pairing. Supported by parent reports means at least one side rests on reviewers or parents. Unverified means we found no source for at least one side.
