As we mention in the story, toys and gadgets known as “fidgets” have been around for a while. Some of your students may use them—they’re items such as chewable pencil tops and toys that are meant to be squeezed hard or stretched. If you’d like to help your class better understand their purpose, you might explain that for some kids, fidgets can calm the part of their brain that has trouble focusing. When kids get to use their fidget, their brain lets them concentrate on other things, like what they need to do in class.
