Description

Grade 8 mathematics focuses on linear algebra and linear functions. Students meet irrational numbers, apply the laws of exponents, use square and cube roots and scientific notation. They connect proportional relationships to lines and slope, solve linear equations and systems of two equations, and define, evaluate and compare functions, modeling relationships with y = mx + b. In geometry they study rotations, reflections, translations and dilations, congruence and similarity, angle relationships, the Pythagorean theorem and volumes of cylinders, cones and spheres. Statistics introduces scatter plots, lines of fit and two-way tables.
