This was my first experience with Rollyo. Rollyo allows you to create a custom type of search engine using only the websites you select. I created a Searchroll for my 4th grade students on Famous Texans. They are currently researching Famous Texans for a research project. Parents and teachers are often concerned with the types of information that students are exposed to when they are researching online. Rollyo is a great tool that allows students to only retrieve information from creditable sources that were selected by the teacher.
Here's a helpful youtube video that shows how to use Rollyo and the Rollbar.
