Course Philosophy

This syllabus outlines a 10-week schedule for mastering the foundational concepts in Art of Problem Solving: Prealgebra. The pace is approximately one chapter per week, though some chapters require more time than others.

The AoPS methodology is built on learning by solving challenging problems. You should not expect to understand everything immediately. The learning happens when you get stuck and work your way out.

Required Textbook

The Art of Problem Solving: Prealgebra

by Richard Rusczyk, David Patrick, Ravi Boppana

ISBN-13: 978-1934124215

Additional reference materials will be provided by the instruction team.

Learning Approach

Read and do the Problems

Complete all "Problems" as you read through each section.

Do the Exercises

Complete all "Exercises" after reading each section.

Mastery

True understanding is demonstrated by successfully solving the Review Problems and Challenge Problems at the end of each chapter. Do not skip these!

Check Solutions

Use the Solutions Manual after you have attempted a problem and are either (1) stuck or (2) want to check your final answer and see an alternative method.

Tips for Success

Consistency is Key

Set aside dedicated time each day to work on the subject. 30-45 minutes every day is better than one 4-hour session on the weekend.

Write Everything Down

Do not do problems in your head. Write out every step, every time. This builds good habits and makes it easier to find mistakes.

Don't Be Afraid to Be Wrong

You will make mistakes. Every mistake is a learning opportunity. When you get a problem wrong, don't just fix the answer; understand why you made the mistake.

Review

Before starting a new chapter, spend 15 minutes reviewing a few problems from the previous chapter to keep the concepts fresh.
