I set up an account in Today's Meet. It was very quick and easy. I love that you can share but it doesn't have to be orally in front of the class. Some students don't want to talk to the whole class and that prevents me from hearing their great ideas or them contributing to our class discussions. It can also be occurring in real time and I can see the feedback right then and there.
I tried Edmoto and could not make an account because I did not know my school code.
I then went to Poll Everywhere. This is an alternate to using Activotes I think. It was OK and very simple to make. It can only work if all students have a phone for texting. They don't always have one.
