I was quite surprised at how thoroughly my niece and nephew were absorbed by this book. The text is very simple, the story is very black and white, but the children were just swept up in it! The concept in the book is very easy for young kids to understand (they probably live versions of this story themselves on a daily basis), and older young kids will get a kick out of watching Martha learn what they already know. Cute story with plenty of opportunities to discuss consequences associated with positivie and negative behavior.
