Use of fidgets and other stress tools

Here is a picture of my new supply of cool fidget tools. I have a whole box of stress balls. We allow students who want to use a fidget tool to use one in class only after they have signed a contract. We use the Responsive Classroom approach so I wrote a description and contract about using the object as a tool not a toy. This has helped regulate the use of these items. We ban anything that makes noise, is messy, or too distracting to peers (like spinners a few years ago).  The Monkey Fidget is my favorite because it is small, quiet, and has a marble inside that the student can simply push back and forth inside the small mesh sleeve. The one draw back is it is small and many of the students who need a fidget also are the same kids that loose things easily. We make the students leave their fidgets in their homeroom. We supply fidgets to our special teachers for use in their instructional spaces. I personally believe most of our students could self-regulate and not need fidget tools if we could provide a second 30 minute recess but since that is not going to occur we continue to try to find tools that help children focus. I would rather have them use a fidget I provide that tie their shoelaces together - that used to happen at my former school that did not have a budget for fidgets.
