I love seeing all the classrooms in Google Slides- obviously! I made a whole video on it, ha! But day to day Canva is more my vibe. If you don't have a Canva account yet, run and make one. It makes your assignments and communications to admins and families look so engaging. I even use it for projects for my family. This video shares a "how to" guide on creating a virtual classroom using canvas.
I love this option because you can download as a PDF with links, leave as a presentation, publish as a website or copy an embed code. It is so versatile and Canva images always look so sharp.
