Each is a short presentation, less than 10 minutes. All are effective and provide an important resources that I integrate into lessons. I have used these videos here with upper-elementary students, middle school students, and even high school students. The key is to include enriched content in a short, attention-grabbing way. You will find that the formats and styles I use work with very wide and diverse age groups.
In this light lesson, students exercise their library shelving skills. A work sheet (provided) invites them to come to the aid of two rambunctious students who have made a mess in the school library.
