Somehow, even by 3rd grade, students think that writing informational pieces somehow begins with copying facts out of books they read. One of the goals for 3rd graders is to take notes on research topics and when my kids noticed this on the feedback form our district has, they mentioned quickly how hard they thought note-taking was. Even after all that we have done with sketch-noting this year, they had little confidence when we started to talk about "research" and "note taking".
So I decided we'd meet a few books in a weeklong unit of study on notetaking/informational reading/research. I ordered 4 picture books about Wangari Maathai as I figured this was a person very few of them knew much about. I also knew that it tied a bit into our Science curriculum. We read Wangari's Trees of Peace, Wangari Maathai: The Woman Who Planted Millions of Trees, Seeds of Change and Mama Miti over 4 days.
