This includes two pages made to look like bookshelves. Each shelf has a section from the Dewey Decimal categories, beginning with 000 - 099. There are 10 titles to cut and paste onto the correct shelf. This can be used as a library activity for a lesson, as a pre-test, post-test, or laminated to use in a center. I use this with my 3rd grade students as an informal or formal assessment. Answer key is included.
