Can you see a potential use for Rollyo in your library?
Not really. So far this is my least favorite thing. I searched "japanese gardens" and came up with one roll which had a couple of sites about gardens in general.
I searched homework as instructed and then narrowed it to multiplication and came up with a few sites that had tips for kids that were strugging and tricks you can use if you don't have a good memory - but nothing fascinating.
I am a researcher and I like to start with the whole world as my source and narrow it down on my own. I treat each search individually and am sometimes surprised where I am led. I'd hate to narrow my focus from the start.
However if I were teaching someone whose skills weren't too polished maybe I would narrow the focus for them by setting up a roll.
