This applies to the kind of events that insurance companies are interested in such as the likelihood of an accident or the length of life of a 30 year old male. Give each pair of children 20 cards. You might like to use sheets of prepared cards in which case the children could colour them in to provide some sort of ownership. Otherwise you will need to direct the children to draw cats on 10 of the cards and dogs on the other 10. When the children have completed their pack of cards demonstrate a game of Cats and Dogs.
Rules Shuffle the cards.
Put the cards face down in one pile. Take turns turning a card from the top of the pile. Compare the two cards. If they are different, the other player takes them. The game continues until all cards are used.
