This 20 page document includes spine label related practice pages (worksheets), exit ticket assessments, and a task card center (there is a version for either horizontal or vertical spine labels). I use it for 4 weeks of lesson plans for one grade in my primary school library, but you could also use the different assessments to differentiate lessons for students of differing ability or grade level. It provides material for fiction call numbers/spine labels. Nonfiction is not included in this
