megscott, there isn't a built in way to do this in Canvas, but Dropout Detective (paid third party solution) has this functionality (we've had it for a while and love it) OR a pretty easy script you could use that would provide this functionality (for free) - Re: Accessing all student grades...
The free solution might initially sound a little technical (and scary), but ultimately it all boils down to downloading GreaseMonkey (or Tamper Monkey) to your browser and then clicking on the script provided at the end of @James ' post. It literally took me less than a minute and it works like a charm!
