A fun plenary or starter game for any subject or topic that doesn't need any preparation. On each slide there are 16 squares with five treasures hidden behind them. Students answer a question and if they get it right they choose a square and get a point/sweet/sticker if they find a treasure. There are 11 slides with treasures hidden in different places and the slide to be used can be chosen randomly by clicking the spinning wheel on the first slide. This activity is based on the gamification theory that random rewards make games more addictive and fun. Note: In presentation mode click on squares to make them disappear and reveal the treasures.
