Who Should Take This Course

This course is for you if you are looking for a fun, challenging and efficient exploration of the crucial points in Algebra, a mainstay of middle and high school math competitions. To take this course, students should have successfully completed our Module 1: Algebra Basics course, or have skipped over it due to prior background.

A highly motivated student who has just completed Pre-Algebra will find this course challenging, but manageable with effort. A student who is currently doing well in Algebra 1 will also learn a lot from the course and will discover some interesting facets of math that they had never realized before. Not recommended for students who can already score 17+ on AMC 8. Still not sure if this is the right course? Feel free to contact us at course-consulting@poshenloh.com to discuss.


Syllabus

How To Use This Course

The best way to build creative thinking skills is to play with challenging new problems every day, especially those for which you don’t know how to start. This course consists of 16 Daily Challenges and 4 Weekly Challenges. Each Daily Challenge has two main math problems and their explanations, with additional mini-problems interspersed throughout the explanations to help reinforce your learning. Don’t worry if they look unfamiliar, just use the whole time given during the problem videos (and hints) to think. You’ll even get to invent your own strategies, which is the fun part!

Even if you figure out how to do the main problem yourself, watching its explanation video is still very beneficial. It will show multiple interesting ways to do the problem and introduce deeper ideas in math using everyday language. 

The way to learn how to solve the widest variety of problems is to learn how to invent your own solution methods! So, we encourage you to solve new problems all on your own instead of working on repetitive exercises. You’ll spend the same time on fewer problems, every one of which needs fresh creativity.

The Discussion function is enabled for all Explanation modules; feel free to use it to dive deeper with other learners!

After every four Daily Challenges, we revisit the topics (with some twists), through a Weekly Challenge problem set that lets you focus uninterrupted for 40 minutes, on a variety of specially designed questions. After doing the problems, please read the explanations, even for the problems you solved. There are a lot of fun math coincidences and insights hidden in the problems.

We recommend pacing the course so that you can play with this way of mathematical thinking for some time every day. 

The standard pace is to choose four days each week to work on the Daily Challenges, plus one hour on the weekend for the Weekly Challenge.
