This is an excellent game to play when you have a group of children who don't know each other well. You can play it with children as young as 4.
Children (and adults) stand in a circle. An adult starts off the game by throwing a beanbag or ball at someone in the circle and asking a question at the same time - such as "What's your name?", "Do you have a brother or sister?", "What's your favourite colour?" and so on. The person who catches the beanbag/ball must answer the question and then throw it on and ask their own question. The game works best if you keep it moving quite quickly, so you may have to step in to prod very young children.
