I discovered this website/service for putting together classes this morning. I work as a software engineer, but teach coding sessions to ~20 8-12 year olds every other Friday for 1.5 hours.
We do our lessons in a lecture format, and I have ~20 volunteers from the local college who help out as well. Currently I am just evaluating the offering to see if it will be a match.
I really like what I see, but I imagine I'll need to do some tailoring since the various game affects are centered around a typical class setting instead of an extra curricular.
If anyone else is out there doing something like a code club I would love to hear about your experiences.
