Regular Live Streams

(Excerpts from Weekly Show)

For several years Po-Shen Loh routinely traveled the country (and world) on a weekly basis, giving math talks in different cities to increase interest and ability in math. When COVID-19 (the coronavirus) made it difficult to host in-person events, he launched a free weekly YouTube Live math show in early 2020. In response to sudden school closures, he started running the free daily YouTube Live stream Ask Math Anything, with Po-Shen Loh on Mon Mar 16, in which he interactively answers math questions asked in real-time via YouTube Live. All upcoming sessions will be announced here on this page, with automatic notifications sent to subscribers to the Official YouTube Channel of the Daily Challenge with Po-Shen Loh.

Due to YouTube's legal restrictions regarding real-time chat, active participation in all live streams is meant for people 13 years of age or older.

This button to join the active live stream will be updated 15 minutes before the stream start time, and all streams will also appear at that time on our Official YouTube Channel.

Daily: Ask Math Anything, with Po-Shen Loh

In each 60-minute weekday live stream, Po-Shen Loh invites students, teachers, parents, and anyone interested in math to post math questions in the YouTube Live interactive chat. He will improvise mini-lessons around them, showing how mathematical reasoning is interconnected, and how learning to think creatively about math can actually simplify the task of learning math itself. He gives preference to questions in Algebra 1, Geometry, and Algebra 2, as they are the gateways to mathematical fluency.

Format. This stream is intentionally friendly and informal. Po-Shen Loh will pick out the most mathematically interesting questions in the chat in real time, and interact with the audience. None of the mini-lessons will be prepared in advance, to give the session a more lively feel.

This show ran every weekday from Monday March 16 – Friday July 3. In July, the show reduced its frequency due to Po-Shen Loh organizing the USA Math Olympiad Program, which ran that month.

Weekly Show

In each 45-minute weekend show, Po-Shen Loh talks to parents and students about learning math more deeply. The goal is to show how it is fun to think creatively about math, and also to provide a global platform for real-time discussion and interaction. These weekend shows are designed for students who are already doing very well in their math class at school, and seek more challenge.

Format. The first 15 minutes will introduce and discuss an interesting math problem specifically chosen to exemplify mathematical thinking. The remaining 30 minutes will be a free-ranging Q&A session on any topic around learning math.

Next Show Time. 8:00pm – 9:00pm Eastern Time (USA), on Saturday, Jul 11, 2020 (Episode 24). Equivalently, 10:00am Sydney Time on Sunday, Jul 12, 2020.
