Polygraph: Find My Four Lines with Pre-Game / Post-Game

A collection of graphs that show 4 different lines. Includes a "pre-game" (WODB) and two "post-game" options (Category Creation and Using Vocabulary), depending on the level of vocabulary previously introduced. Use snapshots to share student "noticings," responses to interstitial questions, formation of categories, and/or use of vocabulary. Focus on vocabulary involving pairs of lines: parallel, perpendicular, horizontal, vertical. May include terms related to triangles and quadrilaterals: right triangle, acute triangle, isosceles triangle, obtuse triangle, rectangle, parallelogram, trapezoid.
