Welcome to a fun and systematic tour of middle school competition math, designed for beginners. Through an original teaching style that develops creative thinking, students will discover the rich world of math that they can build from their foundation.

Course Structure

► Module 0: A sampler of the 5 main areas of mathematics: geometry, combinatorics, algebra, number theory, and probability

Module 1: An introductory Algebra course focusing on basics that will lay a strong foundation for students to explore more useful and deeper topics covered in this course series

► Module 2–6: Each module will rapidly cover fundamental math competition tools used in each of the 5 subject areas

► Module 7–11: Each module will dive deeper into the applications of each of the 5 subject areas 

Note: The 12 courses provided are designed to be taken in their numbered order.

Course Features

► Expand horizons: a step beyond the regular curriculum, focusing on depth instead of learning concepts early

► Challenge level: comparable to MATHCOUNTS Chapter level or AMC8 / AMC10 problems

► Course presentation: engaging, creative, and challenging, with no repetitive practice

► Daily mental workout: designed to build a habit of actively thinking about math

► Self-paced learning: courses remain available to review for 365 days after purchase

► Discussion with peers: provides environment and motivation to learn more and aim higher

All courses are taught by Po-Shen Loh, a social entrepreneur who works across the full spectrum of mathematics and education, in diverse areas around the world. He is the founder of the free personalized learning platform, an education technology social enterprise which algorithmically curates openly licensed math and science lessons and problems contributed by the world. Sales of these online courses support the development of these social initiatives.

To create these lessons Loh draws from his experience as a mathematics professor at Carnegie Mellon University and also as the national coach of the USA International Mathematical Olympiad team. His research and educational outreach takes him to cities across the world, reaching over 10,000 people annually through public lectures and in-person events, and he has featured in or co-created videos totaling over 5 million YouTube views.

Professor Loh has been continually involved in math competitions since he was a contestant in the 1990's. He ranked 3rd at the National MATHCOUNTS competition in middle school, and won a silver medal for the United States of America as a contestant at the International Mathematical Olympiad in high school.
