Summary
- A math teacher was suspended for a quiz containing fat-shaming and sexist questions.
- YouTube videos show the teacher writing math on his bare feet for students.
- Students are filmed dancing for extra credit in some of his videos.

A veteran math teacher at Lowell High School in San Francisco, Tom Chan, has been placed on indefinite leave following accusations of assigning a fat-shaming and sexist quiz. The quiz reportedly included questions about students' weights and the cost of dates based on a woman's weight. This controversy has brought attention to Chan's YouTube channel, where over 200 videos showcase his unconventional teaching techniques.
Clips from the channel reveal Chan writing calculus and geometry concepts on his bare feet, and students performing dances for extra credit, a practice some parents deem humiliating. The school principal confirmed Chan's leave and stated the district is actively investigating the complaints.
Chan has taught at the school for over 20 years. While some students and parents describe his methods as intended humor, others, including concerned parents, view them as inappropriate and potentially abusive. The school district has reiterated its commitment to student safety and encouraged open communication regarding such issues.
