The math course I was working from was: thegreatcourses.com/courses/secrets-of-mental-math, but Arthur Benjamin also has a book teaching the same things: bookshop.org/a/91541/9780307338402. The bookshop link is an affiliate link so I get a buck or something if you buy it through this link (thanks, if you do!).
Some thoughts on interleaved practice: youtu.be/AWTYfzxBwPg
Some thoughts on deliberate practice: youtu.be/WbUOY9ioIqw (tackling some myths about deliberate practice); youtu.be/3SZDj5TEhU0 (on criticisms of the deliberate practice model)
A quick intro to the novice to expert transition: youtu.be/qwDzjQsM3yQ
