This is a very good way to link reading to art. Here you will find a ready-made worksheet with instructions for creating a book jacket to report on a book. There are rubrics at the end so your children know what you will be evaluating on the finished work. You may display the book jackets by genre.
You can also use this plan and adapt it for KS3 where instead of creating the book jacket in paper, they can use Publisher or Word to do it digitally and then print, if desired.
