Today was our field trip to Chambers Building!

This morning, we began our discussion of ratios in earnest.  We began with the coffee problem, then moved into the “Perfect Pint of Pink Paint” problem.  Through these we could see how ratios can be represented in multiple ways, as well as how ratios interact with multiplying by a little more and adding a little more.

Before lunch we welcomed Dean David Monk and Associate Dean Greg Kelly from the College of Education.

After lunch we discussed the patterns in our own questioning that we heard in our teaching recordings. We watched a video clip of an 8th-grade teacher working on the “Two Tanks” problem and analyzed her questioning.

Here is the list of question stems Fran promised to share.

Andrew showed another way to think about multiplication with integers, and we ended the day doing more proportion problems (“the perfect pitcher of purple punch”).

For homework:

Read whichever short message was handed out to you in class today. (Either “Let it go” or “Effectiveness and efficiency”).

Revisit the “Perfect pitcher of purple punch” A-E in light of Laura’s bar model and a table-based approach.
