Jason Ermer’s Collaborative Mathematics project has launched its first video challenge. The project aims to allow mathematics to happen collaboratively via the medium of online videos, and video responses. The idea is that having watched the challenge video, you work with a group of friends (collaboratively) and post a response video, and then watch others’ response videos, and hopefully somewhere along the line mathematics will happen.

The site has a section for teachers and parents, indicating that the challenges are suitable for work by a group of students or young people (although YouTube’s minimum age restriction of 13 to post your own videos means children younger than that won’t be able to post their own responses).

The first challenge is on Ermer numbers – five-digit numbers of the form ERMER, where E, R and M represent distinct digits.
