A game that can be used as a plenary or to identify key terms for a lesson. I often use 'fun' categories, followed by a couple more serious ones. I have included a tutorial of how to play and a blank sheet to print out. Students are required to think of words for each category and as soon as they have filled in all the categories in a horizontal line they need to shout 'stop the bus' everyone needs to put their pens down and they can score points by putting original words in. Teacher or student to pick the letter that the whole class use. Please see tutorial for more detail. Only trouble I have had is trying to score the class as a whole when they play individually. I often just use the person who has said stop the bus first.
