One morning I was reading to a group of mature 4 year olds. When I introduced the book title and was explaining its meaning, a hand in the back row shot up.
I called on the young girl and she asked with a worried look, “Is that a GOOD word or a BAD word?” After I explained the definition, gave examples and reassured her that the word was indeed a good one, she relaxed.
She had obviously been instructed in appropriate vocabulary and was developing an organizational system about the word’s proper use. This skill, known as Classification, is predominantly a math skill. We see it in toddlers as they sort blocks by shape or color. And we see it in children as they line up cars according to some common characteristic.
