Choose fidget and fiddle toys that aren't too large or too noisy. Many teachers and trainers worry their "toys" will be distracting. But the opposite is true. Fidget toys can help people focus better because they use up our "floating attention." Floating attention is the distractable part of our brain that protected our pre-historic selves from predators. In classrooms these days, we're better off occupying our minds with brainless activities, that won't divert our minds from important learning topics.
