A resource I had used in high school and college was box collaboration. I had forgotten how easy and seamless it was to share and collaborate using it. As a kindergarten teacher, I think box is a bit too advanced for the younger audience but it made my think of the SeeSaw app I used in my classroom for students to collaborate. I did not come across this as a site to explore for this thread but may have easily overlooked it.
Hi!
I have never heard of this website, but I looked into it after you mentioned it, and I could use this in my classroom with my students and even my coworkers because I would be able to connect with everyone and make sure we are collaborating!
