Good Online Jobs for SAHMs?

Hey! So I've been thinking for a while of taking some online classes so I could work from home with a job that has a lot of flexibility. I think coding/programming is a field that is only going to become more important as time goes on, BUT I know nothing about it and don't really have an interest in it personally. I just can't think of anything else that is a good option for a SAHM and could pay well. I HATE talking on the telephone and it's not very practical with young kids anyway so all those jobs that you call people for is a huge NO GO for me. I love science and like math(to an extent, lol) and am pretty good at both. Any input helps :) so thanks!
