I completely agree that you'll have some that like them and others that don't. Your article presents that fact very well. I'm pretty"old school"and think if you have children that aren't able to pay attention they need to use that energy in play. My personal opinion is that more outside time and play time is beneficial to children, and toys might not have a place in certain learning settings. If the teacher is allowed to be flexible in lesson plans, he can then adapt to his class to allow play to be incorporated into learning. I don't have the imagination of how a fidget spinner can be used but there are some amazing teachers out there that should have the opportunity to teach their students in whatever way they see fit.
