This is not an assignment - this is just a useful file for classroom learning. (When you open it, you'll figure out what value it has.) Anytime in Edlio, don't pay attention to Edlio's automatically generated "Due Dates." Those are meaningless. I, the teacher, will make any due dates clear to you either in the classroom in person or on Google Classroom.
Also, in the assignment description, like I'm typing now, I might tell you the due date, if the attached file happens to be an assignment. If I type or say a due date, it's a real due date. But quite often, these Edlio postings will just be useful spreadsheets (and sometimes notes) with no due dates, as opposed to them being assignments. If something is an assignment, I will be loud and clear about it, and usually in at least two places.
The main reason I'm using Edlio to post some files is for Microsoft Excel spreadsheets. Google's "Sheets" product conversion is insufficient for our class needs. Microsoft Excel spreadsheets are really helpful to students for learning.
Edlio is a good place for us to house certain files for you use, and it's easy to just give you the link to them on the Google Classroom stream.
