Builds a strong sense of belonging to something special... your class... Encourages differences and similarities to recognised and valued... Hugely improves our efforts at inclusion... The students quickly came out of their shells and are blossoming... Reveals much of the nature of the students... Gets us buzzing as a group... Encourages participants to take part in their own game and go and find things out from others... brilliant ice breaker game... Helped to resolve a huge problem we had in getting students to gel... Switches the students
brains on from the moment go... Helps to break down various
barriers... Gives a big boost to developing important life skills... This gives a great insight and a fantastic array of examples, clues and hints as to the characters of each individual in the group... Helps participants learn some things about themselves...
