I absolutely LOVE this idea from Angela Gadtke from Seesaw. She has created a back to school letter template that can be posted on Seesaw and scanned using the Seesaw QR code feature. This would be a fun way to introduce students and parents to Seesaw, as well as a fun "meet the teacher" intro! Click the image to be taken to an editable Google Drawing with instructions on how to use this template.
Another idea is to create an "about me" collage using the free app Pic Collage for Kids, then post this to Seesaw and provide parents and students with the Seesaw QR code to scan. Here's an example of that idea from Kami Butterfield.
