Whew! This was a TOUGH one. For the first time since the very beginning of the year, when students were not used to the rigor of this method of instruction, I saw students want to give up, with a few feeling very hopeless. This was originally intended to take 1- 2 days but ended up requiring a full four days to complete.

Some notes:
- Mac Bay was saving this one until students had a better understanding of the y-intercept. While I was hoping for more of a "student discovery" moment on this topic, I think Mac Bay's plan is a better investment in time.
- Next time, I will make a directed effort to use terms such as "starting value" and "rate of change."
- Make a set of cards for each pair of students and ask them to right the unit rate on each card, fill in missing scale values, etc.
- Set a definable goal for students to create one set of matching cards. For added differentiation, give students one set of matching cards and ask them 1) to put in correct order, 2) how they are connected and 3) what story the cards tell.
