This is beautifully done.
Some resources for learning FP:
I started with mit-scheme but it was horrible for a vim and ipython user. This helps you configure tmux, vim, and racket for sicp.
That GitHub username reminds me of xkcd 1105. https://xkcd.com/1105/
Both SICP and HTDP are from MIT.
HtDP is published by the MIT Press, but I'm not sure that's the same as saying it's "from MIT". None of the authors of HtDP are at MIT. One is at Northeastern, one at Northwestern, one at Utah, and one at Brown. Lots of CS books are published by MIT Press regardless of whether MIT actually makes use of the material.
Also, HtDP uses PLAI, a language implemented in Racket, which is not pure Scheme, but that's a pretty minor nitpick that doesn't really detract from your point. HtDP is a pretty good textbook, in my (admittedly limited) experience with it.
