Pages is an office program designed by Apple for their own devices, such as the iPhone, iPad, iMac and Macbook. It complements other Apple office programs such as Numbers and Keynote.
The software is similar to what you may be used to using, Microsoft Office.
Microsoft Word is the equivilient of Pages, Excel is Microsoft's version of Numbers and finally Microsoft PowerPoint is similar to Keynote.
By default, when you are working on a Mac and save a Pages document, it will default to a .PAGES file.
Whilst this is absolutely fine, when you upload it to the school, Microsoft Word is not able to read the Apple file format.
You will need to convert or export the PAGES file to Microsoft Word DOCX format, or the OpenOffice XML format.
There are a couple of ways that you can convert a Pages file to a Word document:

Click the ‘Convert’ button and wait for the conversion to finish.
