Time needed: 15 min
Why? To be outside of the classroom is always welcome for everyone. To involve outside environment in the teaching process is very life connected and effective, if you structure this method correctly.
When? Any time when you need to relax your teaching and learning atmosphere.
How? Let a group of students prepare the game and place some things connected to a topic in the garden, the second group of students need to find them, the first group can give hints. The things which will be hided has to be a connection to the topic as well the places where students hide these things has to be connected as well.
Any risks? This needs a good preparation and you need to make sure that both groups understand what is the topic about. The teacher should prepare this very carefully and complete to give both groups the right hints and guidance. Give for everyone a clear time frame, otherwise it will be endless, because its so enjoying.
