To understand the use of an encyclopedia, have your child look through one. Like a dictionary and thesaurus, encyclopedias are listed in alphabetical order. Remind your child that instead of one book like a dictionary, an encyclopedia comes in many volumes. Most volumes are labeled with one letter. An encyclopedia gives information about many topics such as, famous people, places, things, and events. Have your child choose a topic of interest. Encourage your child to look up their topic in an encyclopedia and find as much information as possible.
