My classes and I have been celebrating Poetry Month since the start of April. Students each signed up for a day to bring in poems to read and discuss and I promised them that the last day of poetry (this Thursday) we would have Dunkin Donuts and celebrate. Today I was observed for the first time and one of my classes acted very immaturely. They did things they KNOW they are not supposed to do: take out their cell phones and ask the AP if she wants to look at pictures in the middle of the lesson or throw pens across the room after I tell them to stand up and walk it to the person. I've promised this DD celebration since the first day in April and I don't want to go against my word, but I REALLY am not in the mood to throw them a party when they clearly didn't show that they deserve it. I'm afraid to go back on my word because they will think I don't mean what I say. What would you do in this situation?
