Tops & Bottoms, adapted and illustrated by Janet Stevens (Harcourt)

 This book is about a hare and a bear.  The hare makes a deal with the bear that they will use the bear's land, but the hare will do the work of planting and harvesting the crops.  At the beginning of each season, the bear picks if he wants the top or bottom of whatever is grown.  After bear picks his part, the hare picks what to plant.  Each season, the hare picks crops so that the part bear chose is the part that is thrown out and the part left for the hare is what gets eaten.  

I would use this book for lower to middle elementary students.  This story shows how the hare is the one doing the hard work, and he is the one who profits in the end.  This book could also be used with a science lesson talking about how different crops grow and what part we use from them.
