Where they match

How each one plays by grade

Math Mammoth runs 3 grades further than Beast Academy. If you want one program to carry the subject for the long haul, plan on leaving Beast Academy around grade 5 and choosing again.

Beast Academy

Grades 1-5

Level 1 combines the guide and practice into one book. Owners and the publisher both flag the shapes chapter in 3A as a wall worth skipping and returning to. After Level 5 students move to AoPS Prealgebra, usually around ages 11 to 13.

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 Beast Academy fits

Made for mathematically strong kids who read well and enjoy being stuck on a puzzle for fifteen minutes, often the ones headed toward competition math later. Kids working at grade level, kids with math anxiety, and kids who need the steps demonstrated first tend to bounce off it hard.

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. Families who want video instruction, scripted teaching, or a program that carries them through high school won't find it here, and neither will anyone whose child isn't reading well yet.
