For Parents

Before COVID, Prof. Loh used to travel the country on a weekly basis, holding Q&A sessions for parents of 4th–8th graders to discuss strategies for developing mathematical creativity. He is now reorganizing this interactive outreach online, arranged by region. Whenever any region reaches 50 interested people, he organizes a Zoom session for that region.

For Students

(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 made it difficult to host in-person events, he launched a YouTube Live math show, Ask Math Anything, with Po-Shen Loh, in which he interactively answers math questions asked in real-time via YouTube Live. In 2021, several episodes of this show are in collaboration with MATHCOUNTS, where he will demonstrate the problem-solving process by showing how he thinks through problems that he is seeing for the first time.

In general, all upcoming public Live sessions (with all partners) 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.

If you are unable to join the YouTube streams (for example, if your country blocks YouTube), you are welcome to join this alternate Zoom link. Po-Shen Loh will not be actively paying attention to the Zoom link, but it will stream his session. This Zoom link will be activated for all of the live streams advertised on this page, except for the Carnegie Mellon University classes.

Upcoming Show Times:
Sat May 1 (Math League Middle School State Live Solve): 8:00 – 9:00pm Eastern Time
Sun May 2 (Math League Middle School State Live Solve): 8:00 – 9:00pm Eastern Time

Carnegie Mellon University Discrete Mathematics Course

Due to the COVID-19 pandemic, Carnegie Mellon University is protecting the health and safety of its community by holding large classes online. In the Spring 2021 semester, Prof. Loh is teaching an undergraduate course in Discrete Mathematics. It will not only teach the core concepts in that subject, but will also introduce a large number of surprising insights and connections between Combinatorics and other areas.

People from outside Carnegie Mellon University are welcome to tune in to see how the class is taught, but unfortunately Prof. Loh will not be observing or responding to the real-time comments in YouTube. He will be responding to the students participating in the private Carnegie Mellon University Zoom chat.

Class Times:
Mon, Wed, and Fri from 2:10 – 3:00pm Eastern Time, starting Mon Feb 1.
