Recently my pupils have been enjoying revising vocabulary using fly swatters to hit appropriate words or pictures on the board. Two pupils volunteer to come out to the front with their back to the board. On the board I have either words or pictures. Either I - or pupils - shout out French words which are represented on the board. The pupils have to turn around as quickly as they can and hit the right answer. I am sure I found this idea on pinterest so sorry can't give exact credit. I normally make several slides with the images in different places and switch slides when the pupils are turned away from the board. This stops them from just memorizing the place.
