Fabulous, ultra-thorough resource on reading workshop.  The whole site is practically a how-to book.

This site was recommended by a teacher who has used it with quite a  bit of success with students.

I think I'd find this a bit overwhelming as a future teacher (and even now as a current teacher!), but this is a great list of blogs.

Does a nice job of summarizing brain research and how to apply it

LiveBinders is a great tool to save and organize resources.  Here are some of the top ones for 2012

This site provides an extensive collection of free resources, math games, and handson math activities aligned with the Common Core State Standards for Mathematics. Our math printables are suitable for use in math centers, small group or whole class settings. Instructions for each activity are presented in large print on a task card in child-friendly language to enable students to work on tasks independently after a brief introduction to the task. All materials and activities on the site are designed to support the Common Core State Standards and are based on the belief that effective mathematical learning is best achieved when students are given frequent opportunities to develop their own problem solving strategies, to pose questions, and to engage in mathematical inquiry through the use of open-ended tasks.

PBLU is an online social network of educators who continually learn and share how to do Project Based Learning. PBLU provides free online two-week classes and Common Core aligned projects that teachers customize and implement while receiving tips from an experienced PBL facilitator and feedback from the online community. PBLU launches the summer of 2012.

Mangahigh.com is one of the world's first games-based-learning sites, where students learn Mathematics via purpose-built casual games that balance fun and learning.

As usual, a very extensive list from Cybraryman

Great site from a teacher I've "known" for years online.  This is her page for a presentation on using googlesites.  Teachers (and students) will be able to create their own websites.

This resource from Annenberg includes a video on Olympic history and other resources.

Wonderful classroom website. What a great way to involve all stakeholders: staff, students and parents. Beth Newingham and Holly Gordon share a third grade classroom in Troy, Michigan.

Learner Express is a gallery of short video modules distilled from over 350 hours in the Annenberg Learner Collection. The science topics are useful in a STEM-based curriculum, while the math topics align with the Common Core Standards. You can quickly locate 1-5 minute videos to enhance classroom or professional learning. Indexed, annotated, and linked to related resources,
