So if it keeps your more focused...that means it could help with something like ADD right?
Note, I said "help", not "cure."
I do think the cube could help. I do not think the spinner can.
I honestly didn't even see that you were talking about the cubes. I actually don't even know what the cubes are. But whatever, maybe the cubes can help XD.
Look them up, they're a great idea. Something to play with thoughtlessly.
The spinner I think defeats the purpose. You have to put thought into spinning it and holding it. They're toys. They certainly have no place in classrooms.
They are driving teachers crazy. When I was a kid it was yoyos.
