This google sheet will help you create a customized daily planner. In order to edit the file, you will need to click "File" then "make a copy." When you edit the Weekly sheet, each daily sheet (Monday-Sunday) will automatically populate.
As an added bonus: If you like my graphic organizer, I've included copies of it for each day that automatically populate when you edit their cooresponding sheet! If that type of organizer doesn't work for you, go ahead and manually edit them (or delete them).
