In fact, sometimes we parents are used to looking at the world of children from the perspective of adults, which makes things complicated. Since the children take the initiative to give gifts to teachers, they must like this teacher. Teachers who are liked by children will definitely not care about the value of the gift itself.
You can guide children to make something by hand, such as a greeting card, or a picture drawn by the children themselves, and write blessings to the teacher. It's very good. You can also ask the children their own ideas. Many times, children's imagination is incomparable to adults. You can give appropriate ideological guidance.
My son once made a magazine for his teacher - he excerpted all the words about the teacher in his diary, and each page also had his own drawings. After the completion, it was a thick book. We were all surprised by the children's creative talent. Haha, you can give it a try!
