Grade 8 Topics
The year algebra begins in earnest — real numbers, exponents, roots, linear equations and functions, and the data that lives on a graph. Each topic is taught from the ground up with interactive, self-checking lessons.
The course — 7 topics, in order
- 01The Real Number SystemRational vs. irrational numbers, terminating and repeating decimals, classifying the reals, and placing any number on the line.6 lessons
- 02Exponents & Scientific NotationThe laws of exponents, zero and negative powers, and writing huge and tiny numbers in scientific notation.6 lessons
- 03Square & Cube RootsSquare roots and cube roots, perfect squares and cubes, and solving equations like x² = 49 and x³ = 8.6 lessons
- 04Linear EquationsMulti-step equations, variables on both sides, and equations with no solution or infinitely many.6 lessons
- 05Linear FunctionsSlope and rate of change, y = mx + b, and reading a line four ways: table, graph, equation, and words.Soon
- 06Systems of Linear EquationsTwo lines at once — solving by graphing, substitution, and elimination, and what the intersection means.Soon
- 07Scatter Plots & Bivariate DataPlotting paired data, spotting correlation, fitting a trend line, and reading two-way tables.Soon
