Prealgebra 1
Summary
In AoPS Prealgebra 1, middle school students build the foundation they need to succeed in the next course on their journey. Students explore key topics in number theory and algebra: exponents and exponent laws, common divisors and multiples, linear equations, inequalities, ratio and proportion, conversion, speed, and more.
Prealgebra 1 is available as a live course that meets online weekly for 75-minute sessions, or as a self-paced course. Our self-paced course allows students to move ahead at their preferred pace, with automated interactive instruction replacing the live class meeting times. Both course styles offer instructor feedback on student work, as well as office hours and a class message board for student support throughout the course.
Prealgebra 1: 16 Weeks
Our weekly live Prealgebra 1 course brings together eager young problem solvers from around the world for 75-minute classes with an experienced instructor and multiple assistants. Students also learn from our Prealgebra textbook and videos, while honing their skills on several types of homework problems. Furthermore, they can use the class message board to collaborate with their peers and receive help from instructors outside of class time.

Why AoPS?
Extraordinary Live Instruction from Accomplished Faculty
Our teachers were outstanding math students themselves, and many were winners of major math awards as well as recipients of degrees from schools like MIT, Harvard, Stanford, and Princeton. Our instructors understand from their personal experiences how to inspire and challenge eager learners, and they serve as role models for our students who aspire to similar success.
Active Learning
Learning is not a spectator sport. Students best learn by tackling hard problems themselves, not by watching others do the work. In our classes, instructors start with questions, challenging the students to find the key insights on their own. This helps students learn how to generate new ideas as required, and to develop new skills as needed. When students inevitably get stuck, teachers and assistants provide hints and more direct instruction. After students have solved a problem, instructors reinforce important concepts and strategies. Then–it's on to the next problem!
Focus on Non-Routine, Challenging Problems
Thirty years ago, many intellectual careers consisted of repeatedly solving routine problems. Computers fill most of those roles now. Successful people in the next generation will need to develop new skills throughout their careers as their older skills become obsolete. To prepare our students for this challenging future, we go well beyond the basics in our courses, showing students how to apply fundamentals to problems that are not replicas of problems they've already seen. This teaches students how to learn, so they'll be ready for the rigors of top-tier colleges and internationally competitive careers.
Multiple Learning Avenues
Students learn in many ways, so we deliver instruction in multiple forms. In addition to our live classes, our students can read the Prealgebra textbook, watch videos, solve many different types of homework problems, and participate in mathematical conversations with instructors and other students on the class message board.

Who Should Take This Class?
This course is ideal for students who have completed an elementary school (grades 1-5) math curriculum and are eager for a more challenging mathematical experience. Students can try the Prealgebra 1 "Are You Ready?" diagnostic test to see if they are prepared to take this course.
Prealgebra 1 is also the next step for students who have completed grade 5 of our elementary school curriculum, Beast Academy. (But you don't have to be a Beast Academy student to take Prealgebra 1!)
Each class session is 75 minutes long, and brings together eager students with outstanding instructors for a highly interactive mathematical conversation. Students whose schedules don't allow participation in the live classes, or who wish to pursue their studies at their own pace, should consider our self-paced version of Prealgebra 1.
