We used it to focus on 1 to 2 activities that we will be doing this summer. The students then decorated the glasses and glued them to a folder. They were able to decorate the background of thee folder, however they liked. We added all of their end of the year awards to the folder after our awards ceremony.
You could just have them create a background and hand it as a fun display or just to send home. It would also make a great back to school activity for students to talk about what they did over the summer.
