8th Grade Math Worksheets

Eighth grade is the step into algebra and functions: students work with exponents, square roots and scientific notation, connect slope to proportional relationships, solve linear equations, and identify and compare functions. In geometry they use transformations, congruence and similarity, the Pythagorean Theorem, and volumes of cylinders, cones and spheres. Every worksheet below is free, prints as a PDF with an answer key, and can be assigned online.
