Where they match

How each one plays by grade

Dimensions Math (Singapore Math)

Grades PreK-8

Parent-taught in PK-2 with the heaviest prep of the line, semi-independent by grades 4 and 5, and expected to be independent from grade 6 on. Homeschool parent support thins at grade 6 and again at 7 and 8, so plan an exit or a tutor there.

Math Mammoth

Grades 1-8

Independence is gated by reading, not by math. Grades 1 and 2 are parent-led in practice despite the text being written to the student, and owners are blunt that the self-teaching framing oversells it for weak readers. Grade 4 is a difficulty spike. Grade 7 is a standalone pre-algebra course and grade 8 covers only part of Algebra 1, so families bridge to a different publisher for high school.

Who Math Mammoth fits

Fits budget-minded families with several kids, parents who want math off their plate without a screen, and fluent readers who can absorb a written explanation and get to work.
