SWBAT determine missing coordinates given the slope of a line.

Big Idea

You've found slope before, given two points. But what if I gave you one point and the slope? Could you find the other point?

Warm Up

10 minutes

Today's Warm Up is a Mad Math Minute.

For an overview of the structure of the entire lesson, watch my Lesson Structure Overview video.

At this point in the year, I wanted to experiment with driving procedural fluency.  In this case, I wanted to not only work on a speed drill - for example, single-digit multiplication facts - but also see, in a teacher-as-researcher moment, whether or not fluency is correlated with math average overall.  Please see the reflection section for a discussion of the results of this informal experiment.
