Edmodo is an excellent social learning platform for your classroom.  It is a great way to connect, exchange ideas and share content.  If you regularly use this software or are thinking about starting, three key features to know are as follows:

1.  Library -  Use this to organize and share electronic materials.  Instead of uploading multiple files to one post (which can make the home view very long), create a folder in your online library and click one button to share it with students.  The Library also helps to organize your materials for future instruction.

2.  Small Groups - You can create smaller groups within your classes.  This is an excellent feature for group work and small group discussion.  

3.  Quiz - Create quizzes for students with multiple choice, true/false, fill in the blank and short answer questions.  Great immediate feedback for both you and students.
