I am (hopefully) accomplishing this goal by interweaving my Genre of the Month lessons with lessons about call numbers, sections in the Media Center and using Destiny, our online catalog.
This month I taught a lesson about fantasy fiction to my second, third, fourth, and fifth grade classes and reviewed the different sections of the Media Center as well as how to locate a book using Destiny. I made a PowerPoint to discuss these items and at the end of the lesson, I had students do an activity where they had to look at the call number of a book and tell what section of the Media Center they would go to find the book. I emphasized the importance of using the provided search slips next to the computers to write down the title and call number of the book so that they wouldn't have to run back and forth from the computer to the shelves if they forgot what they were looking for. I think it has worked because I am finding search slips all over the Media Center. Apparently I needed to remind them to throw their search slips away once they locate a book, not leave them on the shelves. LOL At least they are using the slips.
If you're interested in the activity sheet, you can get a copy here.
You can also snag a copy of the search slips I use here.
