These are really good, but it’s the last one that I really love. The first thing I thought of when I read your title was a children’s tv character who teaches kids to count. Like, a group of kids are quarreling over how to divide candy and a voice off-screen would say “What you need is to be a little bit more mathemagical!” and the camera would pan to this numerical wonder. Followed by all the kids exclaiming “It’s the Number Witch!”

Probably ends with a lovely little song about how proper division is sharing :)
