If you were to scour Google Drive templates and scripts you would find some tools for making flash cards, but none of them would be as simple to use as Flippity.net.  Flippity is a tool that allows you to create online flash cards using data in your Google Spreadsheets.  Flippity has great instructions that guide you through using the template, entering your data, and publishing your flashcards.  Once published you can bookmark and/or distribute the url that will allow you or your students to access the flashcards.  Flippity also allows you to to shuffle the cards as well. While memorizing vocabulary does not require the highest level of thinking skills, it is sometimes necessary.  Flippity is a good tool for creating flashcards and distributing them easily.  Once you have done this for your students a couple of time, have them create their own.  I know my own boys did much better with memorizing vocabulary when they had to make the flashcards themselves.
