Each person chooses a name (or makes one up), like Shaun the Sheep, Shirley the Sheep, Timmy the Lamb etc. Sit or stand participants in a circle or in their classroom places. Use a beanbag or a soft small ball and give it to one of the participants, asking them to throw it to someone else, calling out the name of the person they are throwing it to. Ask that person to throw it to someone else. Allow this throwing and catching process to continue until some speed is achieved.

You can later:
Introduce another beanbag or ball so that two are being thrown at the same time. Instruct the thrower to remain silent and tell the catcher to shout out the name of the person who has thrown to them. Instruct the thrower to remain silent and ask everyone to call out the name of the thrower.
