Programming for kids - Lemmings.world

I’m thinking of starting a local group for kids (8-12 yo) to learn programming using Scratch. Do you have any pointers that I might consider? For reference, I’m a senior developer and architect, the programming part will probably be the easiest of it all.

This was a cool talk on teaching programming gradually (with a lang called hedy) at last year’s strangeloop: youtu.be/fmF7HpU_-9k - might be some useful takeaways for you in there
Thanks!
