Fidget toys have been marketed as universal educational supports in the absence of a scientific evidence base. This article gives an overview of the existing literature on the effect of fidget toy use on student attention, behavior, and learning, and a review of two competing theoretical approaches to fidget toys: sensory processing theory and cognitive load theory. Currently, there is not sufficient support for the implementation of fidget toys in the classroom. Suggestions for best practice when using fidget toys in an educational setting are included.
