First of all, it's really good that you have this intention. I think your class teacher will be very touched. But I have to tell you that teachers are forbidden to accept gifts. If you give a gift, not only will your mind be quantified, it will affect the gift-giving atmosphere in the class, but it will also bring trouble to your class teacher.

Therefore, I suggest you don't think about giving too delicate gifts. If you must give the teacher a gift, a well-made small greeting card and a paper crane folded by yourself will be enough. After all, what you want to give is a gift, not property.
