I was discussing family resemblance with a class of 10-year olds. One bright spark informed me: "My mom said that the reason children look like their parents is because of something in your pants". This stumped me for a minute. Then I caught on. "Oh," I said, "You mean it's in your genes." "Right," he replied quite seriously. "It's something in your jeans."
I teach pre-k and we have a housekeeping area set up for our dramatic play. One of the little girls was in the center with one of the little boys the other day and she said, "If you don't straighten up -- I'm LEAVING YOU!" It caught me by surprise. I realized that she must be hearing this at home, but I couldn't help but laughing. It's great how something unsuspected can turn around a day for a teacher.
I was earnestly trying to get the concept of MOOD in literature across to my 4th-graders. I told them it was the emotion(s) the author made you feel, and asked them for another word for "emotions." (I was looking for "feelings.") One bright boy raised his hand and confidently said "hormones."
