I was just on Instagram browsing #TeachersFollowTeachers and one teacher posted a picture of a fidget bit. It's a little basket that has things for students to to keep their hands busy while helping them stay focused as well. For example, this teacher has some spiral coil key chains, some cut up pool noodles, and some dryer balls. Is this stuff actually useful. I fell like my students would be playing with the items rather than just keeping their hands busy. Anyone use something like this?
