This is a set of QR Code task cards, one question per card, a total of 8 cards. Each card has a question asking which fraction (between 2 choices) is either greater or less. Students should work it out, then scan the QR Code with an iPod, iPad or other device with a QR Code reader. This will take them to the correct answer to check their work. I usually print these two to a page, because they really don't need to be full page size for students to use them.
