2. The purpose of this lesson is to teach students
about the fundamentals of the Dewey Decimal
System to enable them to locate books in the
library. Many students are overwhelmed when
entering the library because of the vast
amounts of books on the shelves. Learning the
Dewey Decimal Classification System will
guide the students to the books of their choice!

arrangement of subjects of nonfiction
books, and it classifies books by dividing
them into 10 main subject groups that are
called categories. Each category is
represented by figures beginning with 000
and going on to 999. In other words, it is a
system of numbers used to mark and
arrange mostly non fiction books.
