An American English teacher tells a class of 5-year-old Japanese children, each with a whiteboard and pen in hand: "Let's write down the sentence, 'I am hot.' "

"Chris, put a space between 'am' and 'hot'," the teacher tells a boy, who follows the teacher's advice.

"Look, I'm done!" the boy cheerily says, pointing at his whiteboard with the correct sentence on it.
