Some amazing Google scripts to start the school year off right.

All of these are some great free scripts, you can use to automate your classroom and leverage the power of Google Apps in your classrooms.

Flubaroo http://www.flubaroo.com/
Teacher creates a Google Form with multiple choice questions. Students fill out the form (quiz, assignment). Teacher runs Flubaroo to autocratically grade the assignment. Results are presented with some nice data summaries

doctopus http://www.youpd.org/doctopus

Automates creating, sharing, grading and returning work to students via Google Apps.
Make a spreadsheet with your roster, names and email addresses.
Your starting document (handout, quiz, etc...)  Doctopus will use your roster to share a version of your doc with each student, and the link to the student's work will be located in a column of the spreadsheet next to their names. Your students will then receive an email notification that it's ready for them in their drive folder. When the assignment is completed you can stop their editing rights. Then you assign a grade and give feedback in the spreadsheet. The script automates the process of sending out an email to each student containing the grade and the feedback.  (Check out integration with Goobric for creating Rubrics for grading of these assignments.)  Updated: 8-29-13- Read more about doctopus use in the classroom by a Norris teacher.
