I've started charging them "paws" (our PBIS tickets - they get them for being safe, respectful and responsible) to go to the bathroom. Yesterday, a boy came up to me, "Ms. J, I really have to go to the bathroom but I don't have a paw." I said, "oh, really? What happened to the fistful you had this morning?" And he said, "Man! You're good at this!"
Hahahaha! Yes, I have superpowers.
The best part was that he tried it again today!
Ahhhh, third grade.
