This game provides a review after several lessons over animal classification ( mammals, birds, etc.), metamorphosis, life cycle of a butterfly, warm and cold blooded animals, hibernation, etc. There are a total of twenty questions with some blank cards that you could add further questions if desired. This would be great as a whole class activity in groups of 2-4 or as a center reviewing those Science concepts. This game contains question cards, directions and an answer key. You just need to print the cards and laminate them if you desire. You'll need basic game boards, a die, and game markers ( Skittles, eraser tops, etc.) to play!
