Hi, J-H-H - like you, I'm also a creative person who is bad at math, and I didn't learn to tie my shoes until I was at least 9 or 10. I think it helped when my mom took some time to teach me one-on-one, and she did it in the most encouraging, loving way possible - this was in contrast with the way they taught it at my preschool, with the teachers barking at us, "Come on, come on, this is EASY! You're gonna have to learn SOMETIME!" I didn't find their approach encouraging at all, and in such a big class, I didn't get the one-on-one help I needed. I do remember my mom buying me a lot of velcro and zip-up shoes, and shoelaces that were shaped like wire coils, which were cool.
