new ebook (PDF) titled A New and Open World for Learning. A New and Open World for Learning is all about using Google's products and services in education. The ebook is clearly a marketing vehicle for Google Apps for Education, but you will find some good examples of and ideas for using Google apps in your school.
As part of the same announcement in which A New and Open World for Learning was released, Google also announced a revamped Google in Education website. The aspects of Google in Education that are probably of most interest to classroom teachers are the lesson plan index and the classroom tools index. The classroom tools index provides links to information about each of the services available to teachers and students. In the classroom tools index you'll find some tutorial or how-to resources.
