Familiarize yourself with books the child likes. If you know that writer Eric Carle is an author that the student likes, go to the library and get a few Eric Carle books.
Know your age group. Check the library for a list of popular books based on grade. Most public libraries can provide you with lists of the most popular books. Young classes also like funny books.
Bring a holiday book. If you're Mystery Reader during the week before a holiday, consider bringing holiday book such as "Trick or Treat Countdown" or "The Night Before Thanksgiving".
Bring a prop or a treat that relates to the book. The kids will appreciate it if you bring a snack to give out after you're reading. It can be as simple as a box of mini donuts.
