Polygraph: Shape Bucket

This Custom Polygraph is designed to spark vocabulary-rich conversations about geometric figures, including polygons and a circle. Key vocabulary that may appear in student questions includes: side, vertex/vertices, angle, scalene, regular, isosceles, equilateral, acute, right, obtuse, parallel, congruent, opposite, triangle, quadrilateral, square, rectangle, parallelogram, trapezoid, kite, pentagon, hexagon, and circle. In the early rounds of the game, students may notice shapes from the list above, even though they may not use those words to describe them. That’s where you can step in. After most students have played 2-3 games, consider taking a short break to discuss strategy, highlight effective questions, and encourage students in their use of increasingly precise academic language. Depending on their readiness, you might encourage your students to use the grid system to determine the length/slope of line segments in order to verify claims about congruent, parallel, and/or perpendicular sides. Then ask them to play several more games, putting that precise language to work. French translation courtesy of Jocelyn Dagenais: https://teacher.desmos.com/polygraph/custom/5aaa8bb0ca70190b27e4a466
