We have been using a website called Symbaloo to display our favorite website links for students. Each center has their own Symbaloo. In some centers we have also added other webmixes (what the page of links is called) for things like keyboarding practice and research projects. Below are the links to our elementary buildings' Symbaloos.

Here is a User Guide for Symbaloo. If you would like to make Symbaloo your homepage, page 2 shows you how to do so from Chrome, Safari, Firefox, and Internet Explorer.
If you would like to use Symbaloo on your iPad or tablet, here is a tutorial. (Hint: I found it most useful to sign up for a free account, login on my iPad, and then the Symbaloo App will save any webmixes I choose.)
