First, introduce storytelling.
1. Tell a story: cry for food.
Teacher: Students, what do you think after listening to the story?
Student: Free to answer.
2. Thinking: Besides the waste in our school, where have you seen waste?
3. Teacher: When we enjoy the delicious food on the table, we may also produce waste. Today, let's talk about waste. Write on the blackboard: How much waste could have been avoided-the waste on the dining table.
Second, the exploration of new knowledge: waste at the dinner table
(1) Take a look, read and think.

5. Teacher's summary:
It is a waste to throw away food you don't like; It is a waste to throw away old toys; It is a waste not to turn off the tap conveniently; Gluttony is also a waste ... this waste is easily overlooked. Maybe the amount wasted at one time is not much, but it is a great amount as time goes on.
