Students run their finger down the FlipperŪ guide to the topic they want to refer to. Then they flip the laminated cards up to reveal the card containing the information needed. Each FlipperŪ guide contains hundreds of rules, examples, and definitions printed on both sides of 5"x 3.5" laminated cards. The laminated cards are attached to a 6.5"x 11" plastic backing. Three holes permit carrying the FlipperŪ guide in a three-ring notebook.
Undefined terms, protractor postulate, pairs of angles, angles of triangles, congruent triangles, rhombus, similar polygons, isosceles triangle. Grades 9-10.
