For our first PBL group assignment, we created a project where 1st grade children would work as a group, select a Dr. Seuss story, read and note key details (such as characters, setting, problem, solution, feeling words, etc.) and then relate characteristics of these characters to themselves. They would have to base their opinions off of examples from the text. Then, using technology, they would create a project that showed these details, their opinions, the examples from the text, and how it related to them.
