# Polygraph: Angle Relationships

This Custom Polygraph is designed to spark vocabulary-rich conversations about angle relationships. Key vocabulary that may appear in student questions includes: parallel, transversal, adjacent, opposite, alternate interior, corresponding, alternate exterior, vertical, and right.

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.

## Marcellus the Giant

## Strength in Numbers

In this activity, students complete three rounds of estimation challenges. After each initial estimate, they view a dot plot of their classmates' responses and decide whether (and how) to revise…

## Card Sort: Exponentials

In this activity, students practice what they've learned about exponential functions by matching equations to properties of the graphs they will produce. They will then use their knowledge of transforming…

## Classy Cats

In this activity, students will begin to see a set of data points as a single thing that can be analyzed, not just a bunch of disconnected points. Students learn…
