I was finding that my students needed a much more “straight forward” model to utilize while creating their paper prototypes. Therefore, I created this prototype using Google Drawings. My students found it very resourceful, I hope yours do as well! Additionally, if your students wanted to create a digital prototype, they could “make a copy” of this document, and customize as needed!
Thank you for sharing and making it customizable!
Always happy to help! Here is a tutorial video for students trying to customize their prototype in Google Drawings
