1.)Set up 4-5 tables in the library media center containing a variety of grocery store items on each one (12-15).
2.)Divide the class into 4-5 small groups. Have each group circle around a table that contains grocery store items.
3.)Discuss the items on the tables with the class and talk about how a grocery store is designed so that specific products can be found easily. Have students share their own experiences.
4.)Have each small group organize the items on their table according to similarities. Have 4-5 different food categories.
5.)As a whole class, walk around the tables and discuss each group's items and they way they have been sorted.
6.)If time allows, combine all of the store items together and have students arrange them on the floor to resemble aisles in a grocery store.
7.)Come back together as a whole group and discuss the fact that a library media center is arranged in a similar way so that people can easily find the books they are looking for. Have students share their ideas about the way books are arranged.
8.)Introduce the ten main categories of the Dewey Decimal System. Explain to students that numbers are used to classify books into categories. Give some examples. Show students the poster of the Dewey Decimal Classification system. (See attachment)
9.)Organize into small groups. Provide each group with 10-12 books that can easily be categorized into the Dewey Decimal System classifications and have them organize their selections. Give each group a copy of the Dewey Decimal Poster to help them organize the books.
10.)Check each groups' books to see if students understand the concept of the Dewey Decimal System. As a whole group, discuss the results. Answer any questions and reteach as necessary.
11.)Once each group's work has been checked, have students list new words they learned during the lesson to create a word wall (i.e. classification, categories). Then have students name some of their favorite types of books and share what section of the media center they would find the book. Then allow students to go to that section and pick out a book.
