Google Classroom Assignments with Kami
Kami makes all your PDFs interactive. It has tons of features, try playing with it a bit. One of my favorites is the ability for students to annotate either in writing OR verbally! I also love the ability to add almost any math symbol you can imagine.The assignment shown in this example is very basic but you can do SO MANY things in Kami.
Any Googly thing can be converted to a PDF to use in Kami! Just attach it as a file from your computer.
After saving it as a PDF, you can upload it into your Google Drive and attach it as a Drive file. That is an extra step, though. So it is really up to you!
