ANSWERS AT YOUR FINGERTIPS! Students run their finger down the Flipper® guide to the topic they want to refer to. Then they "flip" the coated cards up to reveal the card containing the information needed. Each Flipper® guide contains hundreds of rules, examples, and definitions printed on both sides of 5" x 3.5" coated cards. The coated cards are attached to a 6.5" x 11" plastic backing. Three holes permit carrying the Flipper® guide in a three-ring notebook.
