Hi Alexander,
The hour of code is a global event, although it has a greater impact in the US. There is a way to sign up as a volunteer on the Hour of Code website:
https://code.org/volunteer/local
For the most part those teachers that are having their students introduced to coding, know nothing about coding themselves. So usually the activities for the Hour of Code need to be extremely easy to implement and very engaging to students ie the games.
It's great to see what you're doing for the Hour of Code in FL. Are you doing and Wolfram Language based activities?
Thanks,
Adriana
