Create a google doc
Fullfil the document with any information that you want to.
You can share the document with your students by clicking in share (top left).
If you want that your students write directly in the document, I suggest to share it with “read only” permissions and guide them to create a copy to be share with you.
You can add comments by clicking in the “Comments” icon to guide your students or select some text use the right click and choose comment.
NOTE: You can follow your students work in real time as they are writing the document. To have as many windows as documents created and keep your computer performance, I suggest to share the document to a group of students instead of do it individually. So, you only need five of six documents per class, and in each document you can have 4 or 5 students working together, but each one in their on laptop/tablet.
