Dewey Decimal System 400-500

This week in the library we learned about the Dewey Decimal System.  We focused on the 400-500 sections of our library.  The 400's have books on foreign languages, dictionaries, hieroglyphics, and sign language.  The 500's are books on mathematics and natural sciences. There are books about math, space, weather, dinosaurs, habitats, insects, reptiles and mammals in the 500's. This is our second to the largest section in our library.  Here are some of the books we highlighted this week.
