I looked at Voicethread, edmodo, diigo, and skype. I have an account with edmodo, diigo, skype, and with Google docs. Google Docs will enable the kids to share ideas with each other and between classrooms.
We will use skype with the other first grade classes, our reading buddies, and with students involved in FFA.
I also created an account with symbaloo . I plan to use this right away as soon as we get our new technology. It places all the sites in one place for the kids to access.
