I print these using the Labels template 15163 (Shipping Label) in Microsoft Word (for a 2" by 4" label). I then stuck the labels on the front and back of 4x6 index cards. They can then be used for group or pairs quizzing. Our favorite activity is "Quiz-Quiz-Trade" - each student has one card and they face another student with a card. "Quiz" - one student names the card held by the other student; "Quiz" - the other student names the card held by the first student; "Trade" - students trade cards, then go find another partner and repeat.
