Suggestions for use: Teacher should demonstrate the game on the IWB first. The game is ideally suited to pair work, if the school has laptops or a computer room, this would be an ideal site to explore factors. Children could play against each other, with talk and discussion before and after each game. Tactics of the gameplay and a record of moves taken / scores achieved would further the learning potential.
