Wikipedia: Show and Tell (education)
Show and tell is a common expression about showing an audience something and telling them about it. In the United Kingdom, North America, New Zealand and Australia, it is a common classroom activity at early elementary school. It is used to teach young children the skills of public speaking. For example, a child will bring an item from home and will explain to the class why they chose that particular item, where they got it, and other relevant information.
