This lesson plan summarizes a 30-minute library lesson for kindergarten and cross-grade 1st/2nd and 3rd grade classes about the theme of the sun. The purpose is to provide an enjoyable read aloud while teaching basic information and concepts about the sun. Students will gain an understanding of what the sun is and why it is important through reading fiction and nonfiction books, singing songs, and a sun-themed craft. The librarian will check for comprehension through questions during and after the read aloud and activities.
