Scratch

In 2013, I volunteered as a teacher in a one-month programming course using scratch to two classes of second-grade elementary school kids. It was a lot of fun, both for me and for the kids! Hopefully, in the future this will become part of a bigger project with paid teachers.

By the way, Scratch is a fantastic tool for introducing the subject of programming to small children. If you have kids (or nephews), do not miss it!
