What your child should master by the end of 8th Grade
By the end of 8th Grade, a child should command linear equations and functions, the Pythagorean theorem, exponents and scientific notation, and geometric transformations: the core of high-school algebra and geometry readiness. Students analyze relationships between quantities as functions and reason about lines, slope, and systems of equations.
Key learning topics:
Work with integer exponents and scientific notation; estimate square and cube roots
Understand and compute slope; graph and write linear equations (y = mx + b)
Solve linear equations and systems of two linear equations
Understand functions: define, evaluate, compare, and construct them
Apply the Pythagorean theorem to find distances and missing side lengths
Use transformations (translations, reflections, rotations, dilations) for congruence and similarity
Find volume of cylinders, cones, and spheres; analyze two-variable data with scatter plots
Proficiency looks like: a child who can find the slope of y = 2x + 3, solve for the missing leg of a right triangle, simplify expressions with exponents, and graph a line.
