Corner Kick Puns

My classroom has air conditioning, but it only kicks in on warm days like today. When my fifth graders came in this morning, a couple immediately started complaining. "It's freezing in here!"

I had been waiting for this opportunity all year! I pointed to the corner of the room. "Well, if you're cold, you can go stand over there. The corner is 90º!"

The best part was the chorus of incredulous students shouting "really?!" who then went over to investigate. It wasn't until they pointed out that the temperature was same over there that they realized they had been duped.
