My students claim I stalk Mr. Stadel. In a sense, I do, stalk his blog. This week, someone linked to this post here.
I grabbed some markers, chart paper to create the diagrams, passed out the statements and stickies and students started working.
Though, this tends to be more of a middle school task, my students needed to grapple with the definitions and characteristics of various angle pairs. And this task provided the opportunity. There were good conversations, students referring back to their INBs, a few disagreements and some reasoning when a new statement conflicted with a previous placement of an angle.
This is definitely a keeper task.
