Check out Mentava [1] (backed by Garry Tan, IIRC). Their goal is to have kids reading and doing basic math much younger, so that they are ready for high school level coursework by the time they are in late elementary school. I heard about it after my kids were too old for the program, but it sounds interesting. 1: https://www.mentava.com/program https://www.mentava.com/program
