Remember not include students' names. As the teacher I am supposed to set the example and be the disciplinarian. I am supposed to always maintain order. I find it difficult when you have a few clowns in the classroom and they are truly funny.
Laughter is sometimes hard to keep in.
I try but sometimes a students says something that is truly funny and the whole class erupts in laughter and guess what, I do too. I can truly say that sometimes a bit of laughter is the only thing that keeps me from breaking. I had some great teachers who were either funny or had interesting stories to tell. Their humor broke the monotony of an hour long class.
