Khan Academy Algebra 1 Curriculum Overview
This curriculum covers foundational to advanced algebraic concepts organized into 17 units:
- Unit 1: Algebra Foundations: Expressions, variables, combining like terms, and distribution.
- Unit 2: Solving Equations & Inequalities: Multi-step equations, variables on both sides, and compound inequalities.
- Unit 3: Working with Units: Dimensional analysis and unit conversions.
- Unit 4: Linear Equations & Graphs: Slope, intercepts, and graphing linear relationships.
- Unit 5: Forms of Linear Equations: Slope-intercept, point-slope, and standard forms.
- Unit 6: Systems of Equations: Solving via graphing, substitution, and elimination.
- Unit 7: Inequalities (Systems & Graphs): Two-variable inequalities and systems of inequalities.
- Unit 8: Functions: Function notation, domain/range, rate of change, and inverse functions.
- Unit 9: Sequences: Arithmetic and geometric sequences, recursive and explicit formulas.
- Unit 10: Absolute Value & Piecewise Functions: Graphing, shifting, and evaluating step/piecewise functions.
- Unit 11: Exponents & Radicals: Integer exponents, square roots, and cube roots.
- Unit 12: Exponential Growth & Decay: Comparing linear vs. exponential models and graphing growth/decay.
- Unit 13: Quadratics (Multiplying & Factoring): Polynomials, binomial multiplication, and factoring techniques.
- Unit 14: Quadratic Functions & Equations: Parabolas, zero product property, quadratic formula, and completing the square.
- Unit 15: Irrational Numbers: Supplemental unit (does not count toward course mastery).
- Unit 16: Creativity in Algebra: Supplemental unit.
- Unit 17: Teacher Resources: Supplemental unit.
Key Features:
- Each unit includes multiple sub-topics, practice quizzes, and a comprehensive unit test.
