> Anyway, it is possible to do this again and with two small kids I'm very interested to know how. For math, I recommend Hejny method; I have great experience with it (as a student) https://www.h-mat.cz/en/hejny-method https://www.h-mat.cz/en/hejny-method https://www.youtube.com/watch?v=xm0xsBjdMe4 https://www.youtube.com/watch?v=xm0xsBjdMe4 It is now used experimentally in Czech schools, but the textbooks are translated to other languages, too. You can buy the textbook with the teacher's manual and try it at home. Short version is that this method makes kids discover math on their own (with a lot of nudging, of course), so they can enjoy and remember it better. Works both for gifted and average children, but they will progress at different speeds.
