Composite
function is a curriculum topic to cover in Algebra 1 PreAP class in CCISD.
Most students found the topic difficult when I covered it last fall and
I developed this lesson to have them to utilize available resources (lessons)
posted on the web to assist them in learning the topic.

Learners
This
lesson is designed for 9th grade Algebra 1 PreAP class students.
This
lesson should follow a traditional inclass introduction lesson
of composite function lesson which in turn should follow a unit on function.
Back
Standards
 Learn
about composite functions and their domains and ranges.
 Integrate
knowledge in technology by producing a power point presentation.
 Learn
to compare and analyze usefulness of information available on the internet.

Process
This
lesson should be presented at the end of the first introduction lesson
on composite function. It would be great if you can reserve a laptop
cart for your class so that each student could browse the web individually
at first and then share their favorites as a group.
You
might already have a preferred method to form the group, which is fine
with me but you might consider forming a group with mixed ability for
this lesson so that the one who grasps the concept first would be able
to explain to the others.
The
following is listed for the students to follow.
 First you'll be assigned
to a team of 3 students. You will need
a leader, a presenter, and a recorder.
 Once you've picked a role
to play, research the web and locate lessons on Composite Functions.
You may use the resources posted here or
use the ones you've found.
 Select the lesson (on web
site) your group like the best and use it as a base to produce a power
point presentation (between 3 to 5 minutes long) using your own explanation
of what a composite function is.
 The power point should include the following
elements.
 The title slide with the name and the role
of the each group member.
 Slides demonstrating the result of interactive
session using the composite functions java applet, resources
#4. For example, start your interactive session with f(x) = 5x and
g(x) = x+5. Then switch the function by letting f(x) = x+5 and g(x)=5x.
Notice the change. Why is an entry "undefined"? Can you
adjust any of the settings to control the "undefined"
entries?
 One of the slide should discuss the concept
of domain and range of composite functions.
 Include 3 different examples of composite
functions. Each member should provide on example each.
 The last slide should be the reference slide
citing your sources in the correct URL format. Highlight the resource
your group liked the best.
 Check your evaluation
rubric to understand how your work will be evaluated.
Note:
The presentation should be more exciting for students (and you, too) if
you could checkout a smart board for the students to use.
