6 topics. One connected path.
Start with the structure, make one legal move at a time, and check the result in the original problem.
01
Expressions & EquationsTranslate algebraic structure, simplify without changing value, and solve equations with a reliable sequence of reversible moves.
5 resources→02Linear RelationshipsRead slope as a rate, build equations from data, and connect tables, graphs, and formulas without treating them as separate topics.
5 resources→03Systems & InequalitiesSolve simultaneous conditions, choose an efficient method, and describe whole solution regions instead of isolated numbers.
5 resources→04Polynomials & FactoringControl exponents, multiply cleanly, and recognize the factor patterns that make higher-degree algebra manageable.
5 resources→05Rational ExpressionsTrack restrictions, simplify factors legally, combine fractions, and solve equations without losing excluded values.
5 resources→06Radicals, Exponents & FunctionsMove between radical and exponent notation, solve carefully, and use function language to describe inputs, outputs, and inverses.
