Padlet is another useful tool for the classroom. I use it to get collaborative feedback from students, as a way to hold students accountable for center work without all the paper, and as progress checks.
It is easy for students to use. If you set up your own account all you have to do is get a QR code for it, have the students scan the code and they are in! They don’t even need the app on their iPad.
Here is an example of how I used Padlet in a lesson. See the lesson here.
