On Tuesday, I gave my students the worksheet and a half sheet of (their choice of) colored paper and a few minutes to work on the activity. We had a discussion about what they found, then they glued it into their INBs. They seemed to like it so much (or maybe that's just how I perceived it!), that I made another one for discovering the relationship between the two remote interior angles and the exterior angle for Wednesday.

This is what it looks like in the INB.

Neat! Same activity - two different concepts...visual...simple....rigorous.
