Google Document

Google docs has a similar format to Microsoft Word but this new way allows for more collaboration and easier to access for everyone. (not everyone might be able to afford Microsoft office) I would recommend this if you were teaching in a low income area because of the price tag of Microsoft word but this is also good in a high income area because with smart phones and people becoming more connected to the internet it’s an easier way to share things.

There are multiple ways this tool can be used in education like going through a peer edit. (for homework), getting student opinion. Maybe pose the question to the class “what did you learn from the chapter?” so that anyone that has missed that day can be caught up as well as (from a teacher perspective) you can observe what your students did learn in case there is something you want to go back over in class.   

A weakness of the Google document is that it can not really be used in a math setting. 

Here's a sample google document on how this tool can be used.
