Lino is a great resource for any classroom. It can be found on any device including computers, ipads, and smartphones. It can be found here and it is free to make an account. Lino allows you to post and edit sticky notes onto a page and saves your work as you go along. This would be great for sharing ideas and photos, discussions, and making comments in any classroom. There is no age restrictions listed on the site, but it would be best for students who can read and write at an intermediate level.
