### Who Should Take?

Students are ready for this class if they have mastered arithmetic with fractions, decimals, percents, negative numbers, and integer exponents. Most students who have completed a typical Prealgebra course are ready for this course.

Students wishing to cover the material in this course at a more gradual pace should consider Stretch Introduction to Algebra A.

Please note: Our Algebra sequence will likely not match up exactly with your school's. Most students who have completed a Prealgebra course are ready for this course. This course covers much of the algebra of a typical honors Algebra 1 course, some of the content of an honors Algebra 2 course, and some additional material not taught in most standard curricula. Visit our Recommendations page for help in choosing the right class.

### Required Textbook

 Introduction to Algebra By Richard Rusczyk A thorough introduction for students in grades 6-9 to algebra topics such as linear equations, ratios, quadratic equations, special factorizations, complex numbers, graphing linear and quadratic equations, linear and quadratic inequalities, functions, polynomials, exponents and logarithms, absolute value, sequences and series, and more!

I liked the class a lot! It was lots of fun learning fromÂ the instructorÂ and his assistants. I learned much more than I thought was possible on an online course. I feel really confident about my Algebra skills now!
