I love this simple and effective method a teacher can use to keep up with the students' thinking as it develops.
Just have each student share 1 Google document as a journal with you. Put them all in a folder. Then, and this is the magic, have each student add their daily work to the top of the document. You don't need a new document for each little check in. Just add it to the top. Google preview makes it simple simple to check in and see what your student are thinking, what they are getting and where they need help.
