Free CS Lewis Literature Guides

This morning I was looking around and found some free resource guides on CS Lewis.org's site.  You can find them here:  http://www.cslewis.org/resources/studyguides/  The study guides are age appropriate based on the age at which students would read those books.  For example, the guide for The Lion, the Witch, and the Wardrobe is for grades 3-5, but the study guide for Letters to Malcolm is written for high school students.
