Polygraph: Arrays

This Custom Polygraph is designed to spark vocabulary-rich conversations about multiplication and arrays. Key vocabulary that may appear in student questions include but are not limited to: array, rows, columns, product, factors, rectangle, squares. In the early rounds of the game, students may notice features in the models presented from the list above, but they may not use those words to describe them. As you notice this, please step in and ask some "least helpful" questions. 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. Then ask them to play several more games, putting that precise language to work.
