Question

I need an idea for a gift fot my math teacher!

Answer 1

It is difficult without knowing the person. If the teacher is like me, the best generalist gift would be a very good bottle of something alcoholic. Personally I'm not a fan of the usually suggested contraptions and thingamajigs. Don't get me wrong, when I was 14 I would have killed for a Klein bottle or a Gomboc, but now I'm not into  "objects" anymore, especially those whose only function is "exist" (and catch dust).

But maybe she/he is into this kind of things. You can stalk the teacher a little and learn what other interest beside math they have...

Answer 2

Try not to get something cringey. There are many many examples of eg bad maths t-shirts that if someone got me I'd only wear while sleeping, but I'd accept it politely.
