Would you like your students to be able to work independently on standards-based games of your choosing? If so, then you may want to consider setting up a Symbaloo account. Symbaloo is a web 2.0 tool that allows you to build collections of information called webmixes. You can then allow your students to use the webmixes that you have created. Below, I have included webmixes that I use for a center rotation with my kindergarten students and a tutorial on how to set up a Symbaloo account.
