This includes a pdf with the small numbered cameras up to 30 and the middle section. I have on the middle section that you will simply "post the work," so it is more universal. I use an app that I can share work and photos to parents on that I mention, but you could also send an email or however else you communicate with parents.
After downloading, print it out on cardstock and simply glue the cameras on clothespins and put the middle section in a 5x7 frame or use a small hanging chalkboard as I did.
Enjoy your selfies! :-)
