Verified answer

Two ways: 1. Modeling. 2. Direct verbal intervention. For example, if I want to teach you to share, I will first model it by saying something like: Mary, when you are done with the blue car, may I use it? Not all children catch it this way though. If you didn't understand, and then you took the car you wanted, you would upset the other child. I would say, She was using that. You need to give it back and use you words. Ask her, Mary when you are done with it may I have a turn? These kinds of interactions need a lot of support through the early childhood years but most young children learn them quite well as long as they are supported and encouraged in their interactions.
