Hi Amanda I actually like your vibrant idea that teachers role is changing by the end of each period. It will force teachers to keep their skills up to date and students will take advantage of these teachers.
It is good point that those tags or packaging be prompts. But children by themselves cannot reach a conclusion. There should be some educated adults who can guide them or add something new to their conversation.
Actually, I like the ideas of "Tea Timeout" and "make children discuss Writings on tea label". It would be a great opportunity for children to socialize and combine dots in their minds. If we can make children to discuss on different topics, and gain the habit of questioning everything, it would help them to realize their creative confidence.
