Who Should Take This Course
To take this course, students should have a solid background in PreAlgebra and the willingness to concentrate on a single math problem for several minutes. A highly motivated student who has just completed PreAlgebra 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 12+ on AMC 8. Still not sure if this is the right course? Feel free to contact us at courseconsulting@poshenloh.com to discuss.

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 donโt know how to start. This course, which can be finished in 1 month, constitutes of 16ย Daily Challenges and 4ย Weekly Challenges. Each Daily Challenge has two related math problems and their explanations. Donโt worry if they look unfamiliar. Just use the whole time during the problem videos (and hints) to think. Youโll get to invent your own strategies, which is the fun part!
Even if you figure out how to do a 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. This brings advanced math down to earth.
There is only one practice problem in each Daily Challenge (the โYour Turnโ problem), and there arenโt any homework problems. This is because 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. Youโll spend the same time on fewer problems, every one of which needs fresh creativity.
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 flavor of mathematical thinking for a bit of time almost every day.ย
The standard pace is to pick four days each week for four Daily Challenges, plus one hour on the weekend for the Weekly Challenge. If you think this pace is not challenging enough, feel free to double the pace, so that you can finish eight Daily Challenges and two Weekly Challenge each week.
