Day 22

Today's opener utilizes a hopefully interesting problem pulled "straight from the headlines" - well, okay, straight from the news, about the world's largest chocolate bar, which I then turn into a dimensional analysis problem.They then have two practice problems involving graphing using intercepts and finding the intercepts from a graph.

Today's lesson then provides an application problem to link recursive sequences to writing equations and to talk about the concept of y-intercept (we'll get more explicitly to slope shortly, but we talk a bit about it today as well).

Their homework for tonight is to review the notes from the lesson (as always, posted as a PDF to the class blog), and to complete the Graphing Linear Equations by Using Intercepts Online Pre-Assessment on the Moodle.
