To share your class code for Google Classroom I created a template in Google Draw. Make a copy of the template and type the class code at the bottom of the badge.
Feel free to use or modify this graphic, no attribution required.
After entering the class code into the drawing, use the file menu to “Download as” and choose PNG. This downloads a 300×300 pixel image to your computer that you can use on your class website or PD slides to share the class code.
