I had never heard of many of these resources.
Quizlet sounds very useful.
I have a PC at home but I know the schools mostly use Mac - so google drives to share info is important to me as a sub.
I am also a sub and rely heavily on Google Docs for sub plans for the day. I also have a PC at home while Chrome Book and MACs are used in most of the schools where I sub. I found the Cacoo app that allows on line collaboration on a project very similar to collaborations done at work before I retired.
Arianne, I too sub which I do by the day and not as a long term sub where I would have to create plans and we use Mac at school too. There are so many resources to use and as you said Google drive sounds great and after reading your comment this is something that I will have to look in to for my next school year.
