Teaching Procedures Step 1: Lead-in Activity: Show three cups of water: Too hot, Too cold, Just right. Q1: "Can you drink the first one? Why?" (It is too hot to drink). Q2: "Can you drink the third one?" (It is warm enough to drink). Concept: Introduce the balance between “too” and “enough”. Step 2: Rule Discovery Activity: Analyze sentences from Part A and B. 1　 You are old enough to travel alone. 2　 The box is too heavy for him to carry. Q3: "Where does 'enough' sit compared to the adjective? Where does 'too' sit?" (Rule: Adj + Enough / Too + Adj). Q4: "Does 'too...to' mean yes or no?" (It implies a negative result: so heavy that he cannot). Practice: He is too young to go to school. = He is not old enough to go to school. Step 3: Practice Game 1: "Too Much or Enough?"
