- No certificate
Algebra 1 on Khan Academy is a 17-unit course that starts with algebra foundations and solving equations and inequalities, then covers working with units, linear equations and their graphs, the forms of linear equations, systems of equations and systems of inequalities. From there it moves to functions, sequences, absolute value and piecewise functions, exponents and radicals, exponential growth and decay, multiplying and factoring quadratics, quadratic functions and equations, and irrational numbers. A unit on creativity in algebra and a teacher resources unit round it out. The page lists 182 skills; each unit mixes lessons with practice, quizzes and a unit test, and a course challenge tests everything at once.
Your progress on each skill is tracked from Not started to Mastered. The page points learners who feel unready to the separate Get ready for Algebra 1 course. The whole course is free with no paid features, and Khan Academy does not issue certificates. No duration is stated.
