Lesson Plan Vault
The lesson plan vault is simply a place to store your lesson plans. You can copy and paste between the lesson plan vault and your favorite word processor. You can also edit lesson plans in the built-in editor.
If that's all the lesson plan vault did - store lesson plans - it wouldn't be all that great. The real value from the lesson plan vault is the ability to search through lesson plans. You can search through lesson plans that you've created, or search through lesson plans created and shared by other teachers. The more teachers put their lesson plans in the vault, the more they can be shared among teachers.
If you would like to keep your lesson plans private and not share them with other teachers, you can do that too. Just check the box to keep your lesson plan private and it won't be included in other teachers' searches.
