I would keep them for your children to do homework with. My son goes through a whole box of pencils every year for just homework. Mostly because he sharpens them more than necessary and because he deliberately looses them to try to get out of homework. He also will not use a fairly new pencil if the eraser has come off and will not allow me to put a new eraser on the pencil. I currently have 2 new boxes of pencils in my desk just for homework. Why would it hurt to just hang on to them? Even if your kids can't use them for homework this year, they have many years of school and homework ahead of them. If you feel like a pack rat keeping them, then donate them or use them for party favors.
