To "show what they know" I asked students to act out verbs. Using the iPad camera pairs of students photographed each other frozen in different verb poses. They imported the photos into Skitch and labelled the photo with the verb. Each pair created 6 labelled photos. They imported the photos into Pic Collage, re-sized and rotated them to their liking to create a verb poster.
No samples shown because of school district guidelines about student privacy.
