Every Day Life Example
In this classroom example we split the class into two teams – the boys and the girls. Both teams start with zero points. The teacher will ask a question. The first team that raises their hand gets to answer. Right answers get 1 point. Wrong answers get -1 point. The first team to get to 5 points wins.
The boys get the first answer right and the second answer wrong. The girls get the next answer right and the boys get the last answer right.
