Looking for a way to develop flashcards for your students to use on the iPad? How about using flashcards that have already been created by someone else? Flashcardlet is a free application that allows you to do those things easily. This application allows users to create a front-and-back flashcard from scratch. It allows you to copy or combine decks or to download (and modify) flashcard sets from Quizlet that were made by others or made by you (make sure you make your sets public for this to work).
If you are unfamiliar with Quizlet it is well worth a peek. This free Web 2.0 tool has features where students can study flashcards, be tested online, play games to help with mastery, and allows a quiz to be custom designed (true/false, multiple choice, written, etc.). All features of the site work on iPads.
If you would like to learn more about how to use Quizlet take a look at this tutorial (originally designed for Social Studies teachers).
