I have created a special display of picture books about people who, sparked by imagination or insatiable curiosity, had big ideas they developed in order to help others. As I explained to our students, big ideas can come from observing nature or from identifying a community need. Big ideas can lead to social justice, new realms of study, artistic breakthroughs, and even new kinds of toys. Here are a few of my favorites. Scroll over the images for captions. These books are available through your local independent bookseller or several online sources.
