neat interactive chart made by Kathy Schrock that matches Google tools to the levels of Bloom's Revised Taxonomy. That chart is very helpful for selecting a Google tool to support your lesson plans. This morning through a Tweet by Kyle Pace I've learned of another useful resource for teachers interested in exploring the use of Google tools in their classrooms.
This Google Apps Lesson Plan Selector offers dozens of lesson plans that incorporate various Google Apps. You can search for lesson plans by grade level, content area, and Google product.
Applications for Education
If you're trying to develop a lesson plan in which students collaborate with their immediate or global classmates, take a look at the Google Apps Lesson Plan Selector. Even if you don't use any of the lesson plans there, you might get some good ideas to adapt for the unique needs of your students.
