I like the Swift Playgrounds materials a lot. It's a great grounding in Intro to CS. BUT it quickly gets boring for 9 y/o's. Even gamedev, Roblox, etc. They are digital natives so the novelty isn't a fascination to them, the way it was to us: "you mean I can actually program Goldeneye myself at home???" The trick is to get them to see code as an enhancement to life. It's fascinating to see the renaissance in table top RPGs like Dungeons & Dragons amongst the youth today. One time we couldn't find the dice set. So I wrote a simple Python N-sided die. And they were fascinated by BigInt: "you mean I can roll dice with as many sides as I want???"
