Adopt a problem

Register your team

Starting a term project from one of the 613 problems here? Register your team so we know the problem is being worked on. Later — once the study protocol is approved, and only if you say yes to the invitation — we’d ask your team to re-read your problem twice during the term, because how a team’s reading of a problem changes is exactly what this collection is built to study. Registering costs nothing and collects nothing beyond the form below. Running a whole course from the collection? See teach with the collection.
