1) If you do not have access to a FISD Google account (most parents).
You will not be able to view many of these folders. They often contain copyrighted material that cannot be made accessible to the general public. Sorry!
If you do have a FISD Google account, you probably just need to switch Google accounts:
2) (Desktop, Laptop, Smartphone, or Tablet - easy way)
The most fail-proof method is to log out of all Google accounts and then log ONLY into your FISD Google account.
3) (Desktop or Laptop - better way)
In the top-right corner or your web browser, click on the account button and either switch to your FISD account or add a new user with your FISD account. This is the best way to switch between personal and school accounts with the least amount of hassle.
This example uses Google Chrome. On the second line, just to the left of the three vertical dots, you will see your account icon. Yours will probably be something different from Mr. Tyer's face. Click that icon and add your FISD Google account. You can add as many Google accounts as you like and switch between them at any time. It may look different on different browsers, but the process should be the same
4) (Smartphone or Tablet - Occasional fix)
If you are on a browser on a tablet or phone and are having trouble switching accounts, try opening a new tab and then go to "myaccount.google.com" and switch accounts there. Then swap back to this tab, hit refresh and see if it loads for you. This worked for Mr. Tyer using Safari on an iPhone and iPad.
Unfortunately, this is a problem with Google Sites. The program will scale and rearrange the size and shape of the page to fit a smartphone or tablet, but it is not very good at scaling the font size to better fit multiple device sizes and shapes. Hopefully this functionality will improve in future updates.
