We were at the end of a lesson on the order of adjectives. The students shouted out some nouns, randomly: microphone, tie, scooter, banana. I threw a dice in the air. It landed on a six. Suddenly everyone was speaking English, their voices raised in excitement whenever they came up with a new word: a stunning, huge, affordable, checked, Chinese, iron microphone.
Next lesson I got them to describe an object in the classroom. Tall, active, middle-aged, white-skinned, wrote one pair. "What's that?" I asked.
