Sometimes during our language arts lesson, I do silly things that help keep the lesson engaging. I have a group of boys who cannot get over the silliness after we move on. They continue to giggle and giggle and they can't stop. Even after the others are ready to move on. Also, when we are doing a brain break or singing a song during circle time, they laugh so loud that we can't hear the song. I hate to be a nag and I want my students to be able to laugh and be silly sometimes, but these boys cannot shut it off. Is it just something they have to grow out of? I'm sick of always saying "Shhhh" to these boys.
