"8.10" is not merely a number in the teacher's manual. It is the moment when students cross from mimicry to creation. The worksheet provides answers — a scaffold: grammatical notes, suggested glosses, example conversations. But the real work begins when learners take those answers and rehearse them into conversation: switching perspective to play a story, using shoulder leans to indicate shift of topic, threading eye contact to invite a partner into a signed exchange. You can memorize the signs, but the answers become meaningful only when learners make them live.
