This is a game that I created. It is a fairly simple game, entitled "Survival of the Fittest." There can be up to 4 players. Each child picks which animal they want to be and then takes turns rolling a die and moving that amount of spaces. If they end up on their animal's habitat, they don't have to do anything, because their food and shelter is easily accessible to them. If they land on a habitat that does not belong to their animal, they must go on a hunt for food or shelter (they must draw a card). If they find their food or shelter, they get to roll the die on their next turn and continue onward; otherwise they are stuck in that habitat for another turn.
I would use this game as a fast finishers or perhaps at the end of the unit, to help the students to continue thinking about different animals in their respective habitats.
