Padlet allows for easy collaboration between multiple users in real-time or asynchronously. Participants do not need to login, and images, videos, and files can be easily added through dragging and dropping or uploading. Posts are automatically saved and viewable by all. Teachers can use Padlet for activities like KWL charts, brainstorming ideas, organizing concepts into categories, and reflecting on discussions. Privacy settings allow the teacher to control who can view and modify the wall.
