Trading cards are a fantastic tech tech tool that you can use both as a professional and a student. I decided to make mine for my professional learning statement but you could easily bring this tool into the classroom and have students make their own for a variety of purposes. As a teacher, you could even make a class game where you could trade cards with others, or be able to use these cards for different purposes such as a bathroom pass. The website that I created my trading card on even has lessons that incorporate trading cards into them.
