Rounded up because I do believe that one of the best things we can do for our children is teach them to see others' points of view. Granowsky has a series, and so far I've enjoyed every one I've been able to find. Highly recommended to all educators and families.
I also suggest using the idea as a story prompt. Which fable or folk tale can your children tell from the perspective of the 'bad guy' who might actually be a victim?
In my Kindergarten class I read Jack and the Beanstalk towards the beginning of my experience in teaching. Looking back to how I have advanced now, I would like to read this book to older children as a reinterpretation of the story. I think this is an interesting way at looking at the more "gray" aspects of a character. For example, the students may think the giant is mean and scary and not realize that he is hurt because Jack, the supposed hero, stole something from him. This could also be an intriguing way for students to do character studies, such as finding positive and negative traits in characters who are often seen as clear-cut good and evil.
