What should I do after my kid reads a book?

Our quarantined nine year old, Paul just finished Holes.  After he read Mudshark, Paul wrote a book report.  I would like him to learn how to write compositions.  How do kids learn to write?  One, he needs to understand the book: characters, setting, plot, symbols, irony, etc.  Start with a teacher’s guide.  I use reading guides for ideas.  Read about the author.  Make a list of the characters.  Which character did your child identify with and why?  Select six of the questions to answer.  Now watch the film.  Make a list: Similarities to book and Differences from the book.  Did the movie capture the book?  This can be a thesis for a simple Five Paragraph Essay.  Scholastic Bookfiles have several reading guides.  Pick four books.  Your child may prefer to answer the study guide questions.  Fine!  Give him a choice between a book report, questions, or a five paragraph essay.  We are doing Holes, A Wrinkle in Time, Hatchet, and Narnia.  All four have films.  Go for it!
