Oh, the sharpener. So at the school where I was we give the students pencils. They come in with nothing, we provide papers, pencils, everything and at the end we get them back.
The teacher allows the students to get up (with permission) to sharpen them as needed. After 2 days I put the sharpener away.
I noticed that they were constantly sharpening them, and that was just a way to get up walk around, make goofy faces at the class, etc.
I took out 2 manual (quiet

) sharpener, sharpened everything before class, had about 5 pencils left over, so if they needed a sharp one, they could just change it out and I would sharpen them at my convenience.
All of sudden there wasn't as much need for sharp pencils
And the funny thing was that the kids thought I was pretty smart and way ahead of them because there was one more distraction I cut out, that they have been successfully using with their teacher.
