Lesson 1:Piecewise Functions

8/11/2015

STUDENT OUTCOMEThe student will….● Define appropriate quantities from a situation

(a “graphing story”), choose and interpret the scale and the origin for the graph

● Graph the piecewise linear function described in the video.

Homework: pg. S.3 # 1 All parts

CLASSWORK

Turn to Lesson 1 in your binder titled Graphs of Piecewise Functions.

Watch the following video, paying close attention to the man’s elevation over time.Man Walking Down the Stairs (BE SURE TO STOP AT 1:08)

CLASSWORK

What are some observations that you could make about the man’s motion down the stairs in the video?

CLASSWORKHow high do you think he was at the top of the stairs?

How are you estimating that elevation?

Was his elevation always going down? did it ever go up?

If someone asked us to summarize this video in a way that would make sense with little explanation, what would you do?

CLASSWORKWhat kind of things would we need on this graph?

CLASSWORKName of the vertical axis? and what unit of measure will we use?

CLASSWORKName of the Horizontal Axis? and what unit of measure will we use?

PRESENT YOUR WORK

How does yours compare?

CLOSING

● If you were tasked with describing the graph to a friend, how would you do it?

● If they couldn’t see the graph, how would you describe the shape of the graph to them?

CLOSING

● When we graph situations and equations in this class, what things are important that we have labeled on our graphs?

EXIT TICKET

On a separate sheet of paper do the following:● Lay your paper out horizontally● Put your name on the paper● Sketch the graph of the jump you are about

to watch● Do not worry about the units, just sketch the

graph and be sure to label the axes
