last year at school my DS9 sharpened many pencils down to little bits.
His desk was a mess. He also played with little erasers and stuff. His teacher was very tolerant and tried to work with him on this but no success. I think she understood to a certain point how bored he was.

I suggest to him he us a stress ball this year. He rejected the idea. I was excited to think of this and didn't approach it right - like offering choices or letting him come up with ideas. I'm going to try again.

Does anybody have ideas of what he could do with his hands? It can't be too distracting or messy.
