Padlet is like an online bulletin board that you can use in your classroom to display information. You can also use it to collaborate with your students, reflect, share links and pictures, and more--all in a secure location.
Here's a little overview of what Padlet is.
I am introducing grades 3-6 students to Padlet in the Technology Lab by having them post an interesting fact about themselves on a Padlet board I created. They will be using Padlet again in the future, so this was a good introduction for them. Once you explore it a little bit, I bet you'll think of many great ways to use Padlet in your classroom.
