Polyvision is like having a special piece of paper that you can draw on with all different colors of markers. But when you're done drawing, you can wipe it all clean and start again!
Polyvision is actually a high-tech type of whiteboard where you can write, draw, and show pictures during a presentation or meeting. It's made of a special material that lets you erase everything you've written or drawn, like a regular whiteboard, but instead of being one big board, it's made up of smaller panels that can move and rotate. This means that you can keep adding information to your presentation without having to manually erase it every time.
It's really helpful for brainstorming ideas, planning projects, or explaining something to a group of people because it makes it easy to show your thoughts and ideas visually. Plus, since it's reusable, it's a more sustainable solution than using lots of paper or sticky notes.
