Who Should Take?

Students are ready for this class if they have mastered square roots and fractional exponents, order of operations, linear equations and inequalities, ratio, and proportion. We recommend that students have experience with factoring quadratics prior to taking this course.

Please note: Our Algebra sequence will likely not match up exactly with your school's. Most students who have completed our Introduction to Algebra A course or a high-level honors Algebra 1 course in school are ready for this class. However, we encourage students to take our Introduction to Counting and Probability class before beginning this course. 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! This book is used in our Introduction to Algebra A and Introduction to Algebra B courses.

I really enjoyed this course. It was at the perfect level of challenge for me, and I learned a lot (and had fun!). I love the amount of detail that is put into the course. I think the amount of homework was just right, enough to cement in the knowledge without any busywork.
