This is a very simple, six slide Flipchart that I use to introduce each of the sections in our library. I use this to prep students to use the computer catalog. The sections in my library are Everybody (usually Easy in other libraries), Chapter Books (FIC), Dewey (Nonfiction), and Biography. I call renamed our Easy section "Everybody" so that older kids (3-6) do not feel stigmatized about selecting books from that section. I also call our nonfiction section "Dewey" to cut down on confusion since some of the books in that section are definitely not "real" stories.
It also features a practice slide at the end with a call number from each section.
I use the Call Number Activity Page (Also, available in my store) as assessment for this lesson.
