Wall Wisher is an online notice board maker. It gives you a virtual space where you can post short text notes in the same way that you could put post-it notes onto a notice board in your classroom. But this noticeboard can be shared between people all over the world. As well as text notes you can add images, video and links to other websites.

It’s a neat way of getting a shared space to collect ideas from people for a brainstorm. Or to post resources for a topic. Students could ask questions about a topic which you (or each other) can then answer
