I used Tim Pratley’s Power Turtle with a middle schooler as an activity during 2020 quarantine and the kid liked it. Immediate gratification from the graphics and the time-tested Logo turtle worked well. Lo and behold, he didn’t care about the parens lol. I think it’s a good base to build on IMO, although the lessons trail off (they do get into fp concepts maps and stuff).

Also had a similar training exercise derived from clojurebridge materials (one of which leveraged quil + turtle graphics) and custom curricula for adults of various background (about 4/5 non-programmers). Worked great.
