Polygraph: Determine My Tape Diagram with Pre-Game / Post-Game

A collection of tape diagrams that could represent linear equations. Includes a "pre-game" (Notice and Wonder) 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 algebraic expressions and equations: one variable expressions like 3R, 2B or 4G, two term expressions such as 3B + 2R, or equations like 4B + 3R = G
