Polygraph: Sinusoids

THIS USED TO BE A DESMOS ACTIVITY BUT IS NO LONGER SUPPORTED This Custom Polygraph is designed to spark vocabulary-rich conversations about sinusoids. Key vocabulary that may appear in student questions includes: amplitude, periods, maximum, minimum, and shift. In the early rounds of the game, students may notice graph features 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. Then ask them to play several more games, putting that precise language to work.
