TEKS addressed:
(a)(3) Function concepts. Functions represent the
systematic dependence of one quantity on another.
Students use functions to represent and model
problem situations and to analyze and interpret
relationships.
(b)(1) The student understands that a function represents
a dependence of one quantity on another and can be
described in a variety of ways.
(c)(1) The student understands that linear functions can
be represented in different ways and translates
among their various representations.
(c) (2) (C) The student investigates, describes, and
predicts the effects of changes in m and b on
the graph of y = mx + b.
(d)(1)(B) The student investigates, describes, and
predicts the effects of changes in a on the
graph of y = ax2.
Students will be able to:
v recognize graphs of parent functions (linear and quadratic)
v recognize and write down equations for the transformational graphs of parent functions
v use the greeting card they create for future review of these two types of function
III. Resources, materials and
supplies needed
v Digital Camera (if possible more than one)
v Computers with Microsoft word of works program
v Card Stock
v Graphing Calculator and LCD panel

Teacher Does Probing Questions Student Does
Engage: This portion of the engagement will actually be the engagement for the entire unit that starts today. Students will watch the unit anchor video, which asks the question: ÒIs population growing too fast?Ó |
I would like to hear any comments that students might be willing to share about the video, like what do think about the question, do you have any questions, or even what you thought of our wonderful acting performance. |
Expected Student Students
will express there ideas about the video and get the ball rolling for the
unit. |
Explore: Ok, these were all
great ideas and questions about the video that I do not want you to forget
because we will be coming back to each one of them. But for right now we are going to be shifting gears to get
some of the basics out of the way.
Today we are going to
be reviewing two types of functions.
The types that you have
learned so far are linear and quadratic functions. Now I have a fun activity for you all to do that will not
only refresh your memory of these functions but also give you a tool for
later use.
Depending on how many
students know how to use a digital camera, split the class into groups
between 3-5 students each.
Show the entire class
the parent functions of the linear and quadratic functions on the board or
overhead. Students should copy the different functions on their own paper so
that they will have them in their notebooks to review from time to time.
Activity:
1. Take a picture of a
pose by one of your group members showing each parent function.
|
First of all, who can tell me what a function is? And what types do you actually know? Now, who knows how to use a digital camera? We will be exploring these to functions, but are there any questions that you may have now? Are there any questions as to what you will be doing in this activity? You are free to look at old notes, work with the people in your group towards a good post card, ask me, or last resort resort a trustworthy internet site? Which are which ones? |
Expected Student Some form of this hopefully: A function f of a variable x is a rule that assigns to each number x in the function's domain a single number f(x). The word "single" in this definition is very important. They should know linear and quadratic, but some may also say exponential. Hopefully at least three or four, but probably so because students are always becoming more familiar with technology. Ones

Explain: Hand out a sheet that
gives expectations to everyone:
You will be graded on
the following:
|
If
anyone has questions or concerns about the rubric please come and see me. |
|
Extend / Elaborate: If time, discuss exponential equations.
|
What
do they look like? What is the equation? Do you think that you could do this same activity for an
exponential equation? |
Expected Student Something like the following: an equation which contains an exponential quantity, or in which the unknown quantity enters as an exponent. Might say that they look like a very sharp curve. |
Evaluate: The
last 10 minutes of the class the students will exchange cards with another
group in the class. Each group then will have to turn in the cards and they will be graded to see how well they did following the rubric.
|
If
you have any questions about another groupÕs card please ask them. Other groups please do not give away
any answer. Help them to the
answer. |
