Looking at the legacy of the Montreal Olympic Stadium, nicknamed 'The Big Mistake&' because of the amount of money poured into it.\n\nAlso asks the children to think about the impact on the environment and society.\n\nIncludes an activity at the end of creating a legacy for the London 2012 stadium and how to use it creatively and sustainably.\n\nMy kids got so involved in this, it really surprised me how motivated and inventive they were - they even carried on in their own spare time!
