This prompt asks Novice-Mid level students to explain to their teacher what they have in their backpacks and what they are missing.
Use voice recorder, audacity, google voice, or a cell phone to have students record their presentations.
I create paper "backpacks" using my file SCHOOL SUPPLIES FOR COUNTING. I tape a medium sized manilla envelope to the back and slice up the zipper part using an exacta knife. I put a variety of supplies inside that they will have to count. You could do the same with any supplies you have in your classroom.
