Math Mammoth was created by Maria Miller, a math teacher who built the entire curriculum as affordable, parent-light PDF downloads. The Light Blue Series is the complete curriculum (grades 1-8), organized by grade level with two worktexts per year — instruction and practice in the same book, so no separate teacher’s manual is needed. Each grade covers 8-10 chapters organized by topic, with a strong emphasis on conceptual understanding, mental math, and number sense rather than rote memorization.
The Blue Series is a separate library of standalone topical worktexts — fractions, decimals, multiplication, long division, and more — that families buy individually to fill gaps or review specific concepts, independent of grade level. Math Mammoth is most commonly downloaded as a PDF and printed at home, keeping the cost well below most comparable programs. Printed copies are also available through Rainbow Resource and other retailers.
One of the least expensive complete math programs available, period.
Instruction and practice in one book — no teacher’s manual needed.
Standalone topical worktexts let families target specific weak spots.
