Symbaloo

Our classrooms all have laptop carts and I've been looking for a way to organize sites our students use on a regular basis. Through the power of twitter, I found Symbaloo.  Symbaloo is a simple start page that allows you to organize and access favorite sites on one page. It has a great look for kids (as well as adults). Symbaloo allows you to create various webmixes, so I created one for 1st, 2nd, and 3rd grades as well as a subject area for the main subjects. Our school uses Google Apps, so using Google Sites, I create a home page for each grade level. I made that page include the webmix with more general sites (our school homepage, AR, IXL, etc.) I then created a Language Arts, Math, Science, Social Studies, Keyboarding, and Just for Fun site for each grade level. Click here to see our 2nd grade example.
Symbaloo is very user friendly. You can increase or decrease the size of your webmix. You can personalize the icons for each individual square. You can add or delete sites on your webmix any time. You can also embed it in another site, email the link to anyone, keep it private, or share with the world. 
I have shared this with our teachers and they are excited about how easy it will be for their students to access web sites. We also plan on sharing the google site for each grade level with parents so they can make it their homepage on home computers.
Symbaloo is free, but there are paid accounts as well.  Check it out! I think you will be pleased.
