See where the story takes you.
There are the lessons you might plan around a book: math, art, social studies—or no plan at all, just pure enjoyment—and then there’s the emergent curriculum, which the children suggest based on sparks they pick up from your reading. Pay attention to the discussions that follow the reading of a book, and consider how you can use the students’ enthusiasm to boost your educational goals.
How about storytelling? Ask the students to put themselves in the place of a character from the book, or to create a “further adventure” of that character. Take turns telling the story before it is time to write it down & create a book to share. Storytelling before writing helps the student organize their thoughts & gauge audience reaction—it’s a great pre-writing step!
