This is a full 100 square snakes & ladders game for secondary school kids, complete with large dice.  It is based on the ups and downs of being homeless.  The game is laid out on a large canvas (4m x 4m) where students can stand on individual squares, and throw the dice.  Ladders are positive things that happen in the life of a homeless person, snakes negative things.  It is very effective at raising awareness of the issues homeless people face.
