Instructions:1. Sharing is hard for everyone, but we do expect four-year-olds to share as part of their social development.
2. On an index card, write "My Turn Next."
3. Explain to the children that if they are waiting for a desired toy or activity, they can hold the card. Then, when the child who is using the toy or playing in the center is done, the child with the card gets the next turn. She can give the card to another child. For example, three children can play at the water table. But if a fourth child really wants to join, you can restate the rule that only three can play, but offer her the "My Turn Next" card.
4. Depending on the situation and child, you can wait for the natural time to trade, or set a bell.
