In this game, there are 10 Geography 10 and History questions. I printed the geography questions on green paper and the history questions on orange paper. I then cut out the ten answers for each topic onto the same coloured card, laminated them and then stapled them at different heights onto a string that is tied to a brick at the bottom of the water and a float at the top of the water. This is great for differentiation and I put the higher numbers (8,9,10) at the end of the string closest the brick. Of course pupils need goggles but they can do it in teams of 4/5 . The kids absolute love this game and I also have 10 PE and 10 Science questions too.
Wonderful idea. Believe it or not I am in the process of creating 'underwater' problem solving games to be used for groups who do not enjoy or benefit from widths and lengths. Will share when it is finished.
