I’m not joking: the first five episodes of this brand new series dropped today. It’s teaching preschoolers how to think procedurally and algorithmically — from absolute basics — and episode 5 is all about breaking into a henhouse by guessing password sequences.

There are no loop constructs yet, let alone lambda calculus or functors, but I have high hopes; also my 3.5-year-old watched it utterly rapt, and the songs are good, not quite up to the absolute bangers of series 1 of Colourblocks but they are solid tunes, well adjusted to the plot, and so far have avoided the weird and regrettably somewhat phoned-in post-prog-rock (“…the next colour is,… orange!!!”) of the music for series 2 of Colourblocks.

Her brain is vacuuming all this stuff up, and given that (courtesy of Numberblocks) she has been reading numbers up to 100 for several months and can answer questions like “how many is four lots of four?” with better than a 50% hit rate, doing procedural thinking and algorithms appears to me to be a valuable next step for her / the “Blocks” franchise.
