"How is this different from Pinterest?" you might ask. Answer: it's not social media. With Padlet, you control who can post content, who sees the board, and where/how you want it accessible to others. Plus, on Padlet you create notes from scratch and add video, photos, etc. to them, whereas on Pinterest you are actually pinning websites you like.
I created a Padlet board to try out the website. Check out my brainstorm below with a variety of ways you can use it in the classroom. In fact, feel free to add your own ideas to the board. I have the settings adjusted so you can add your own post, but not edit others already on the board. I would love to know what other ideas you come up with for the ESL classroom!
