In Google Drive, click on Storage. If your total is above 5 GB, your Google Drive is no longer backing up new files. Storage is sorted by your largest files.
Spend some time deleting files that you no longer need. Large files that you want to keep should be downloaded to a personal device.
Create folders for each grade level starting with the school year and your grade level (e.g. 19-20 5th Grade or 22-23 8th Grade).
*note* make as many folders as needed for all of your school work in Google Drive
Inside EACH "year" folder, create four new folders:
Language Arts
Math
Science
Social Studies
Sort your files by date modified (newest to oldest). This will allow you to see what date you accessed your files. Then you can drag and drop your files to their appropriate school year folder.
FOR THIS YEAR'S DOCUMENTS (and going forward):
Open your documents, and rename them with the date, class, and assignment.
Move each file into the correct "core content" folder (e.g. math documents go into the math folder).
If you want, you can create an enrichments folder (or four) for those documents.
If you would like to color code folder, right click > change color.
