Time allotted for instruction:

2 class period

Title:

Making Connections With Graphs

Lesson TOPIC:

Interpreting situations for a given graph or creating situations that fit given graphs

TAKS Objective:

Objective 2: The student will demonstrate an understanding of the properties and attributes of functions.

FoCUS TEKS and Student Expectation:

A.2 (C) The student is expected to interpret situations in terms of given graphs or creates situations that fit given graphs

Supporting TEKS and Student Expectations:

A.1 (A) The student is expected to describe independent and dependent quantities in functional relationships
A. 1 (E) The student is expected to interpret and make decisions, predictions, and critical judgments from functional relationships.
A. 6 (A) The student is expected to develop the concept of slope as rate of change and determine slopes from graphs, tables, and algebraic representations

Concepts

Enduring Understandings/Generalizations/Principles
The student will understand that

slope

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

X axis

The horizontal axis of a twodimensional Cartesian coordinate system.

Y axis

The vertical axis of a twodimensional Cartesian coordinate system.

Rate of change

A term which is used to represent the “slope”

Independent variable

A variable whose value determines the value of other variables. A variable that is manipulated, measured, or selected by the researcher as an antecedent condition to an observed behavior

Dependent variable

The dependent variable is the response to the independent variable.
Sometimes the dependent variable is called the outcome variable.

I. Sequence of Activities (Instructional Strategies)
A.
1. Focus Activity – Making Connections with Graphs PowerPoint Slides 15
The teacher will introduce this lesson by:

Guiding the students through PowerPoint slides 15

Facilitating class discussion in the interpretation of the graphs on slides
35

Allowing students TIME to develop their own interpretations

Facilitating discussion of how the interpretation was developed

Making connections (slope, x axis, y axis, dependent variable, independent variable) with math terminology

Leading the students to the connection that their interpretation of the graph will change according to the dependent and independent variables assigned/chosen.
2. Group Activity – “Two Way Interpretation”
The teacher will:

Divide students into groups of 3

Distribute Activity sheets A – D to each group

Groups will interpret each graph two different ways, discuss their interpretations, and present the interpretations to the class
B. Instructional activities
The teacher will use the PowerPoint Presentation – “Making Connections with Graphs” Slides ( 7 21 ) to review the skill of interpreting linear and nonlinear graphs in order to describe rates of change as well as patterns which model real life situations.
C. Guided activity or strategy
1. Teach through PowerPoint
As the teacher “teaches through the PowerPoint”, students will:

Assign independent and dependent variables to graphs

Interpret graphs in light of the independent and dependent variables

Interpret graphs in terms of the rates of change represented

Connect linear and nonlinear graphs to reallife activities

Practice TAKS questions which assess this student expectation
As the teachers “teaches through the PowerPoint”, students will have
opportunities to answer questions from released TAKS tests. The teacher may use
individual white boards or pencil/paper to assess proficiency and identify
students in need of reinforcement.
2. Classwork: Making Connections with Graphs Worksheet
Students will work independently to demonstrate their ability to interpret
situations in terms of given graphs and create situations that fit a given graph.
D. Accommodations/modifications
Teacher may copy “notes pages” of PowerPoint slides and use this
resource to connect specific questions on the classwork assignment to examples the student has already been introduced to. Teacher may provide guided support to students as necessary.
E. Enrichment Activity
Charlie Brown’s Parachute Jump
Retrieved from: http://www.nsa.gov/teachers/ms/algrst38.pdf
The enrichment activity provides students with the opportunity to integrate writing into the math curriculum, utilize a graphic organizer to construct reasoning, and use higher level thinking (such as analysis) in the peer editing process.
II. STUDENT PERFORMANCE
A. Description
Students will demonstrate mastery of the objective by:

Correctly responding to the TAKS questions in the PowerPoint presentation

Scoring at least 80% on the classwork assignment

Scoring at least 70% on the Quiz
B. Accommodations/modifications
Students in need of assistance may be grouped with stronger students for the
student activity
C. Enrichment (see E above)
iii. Assessment of Activities

D. Enrichment
The enrichment activity may be assigned to individual students (GT) or the class
(AP) as deemed appropriate. The students should be graded using the following
rubric:
Final Copy of Story

Score

Student demonstrates:

3
 
Story includes title, setting, characters and plot.

Each event in the story correctly relates to each part of the line on the graph.

Students mathematically connect the part of the story to the part of the graph that they are portraying.

2
 
Story includes title, setting, characters and plot.

The events in the story do not relate to each part of the line on the graph.
or

Students do not mathematically connect the part of the story to the part of the graph that they are portraying.

1
 
Story includes title, setting, characters and plot.

The events in the story do not relate to each part of the line on the graph.

Students do not mathematically connect the part of the story to the part of the graph that they are portraying.

0
 
The story is missing a title, description of setting, characters or plot.

Students do not mathematically connect the part of the story to the part of the graph that they are portraying.

E. Sample discussion questions
What are some reallife examples of “rate of change”?
How would you graphically represent “standing perfectly still in one place for an extended
period of time” if your independentdependent variables are time – distance?
IV. TAKS Preparation
A. Transition to TAKS context:
Overhead sheets will facilitate transition from content to TAKS
Quiz contain multiple TAKS Released Test items
B. Supplementary Materials:
Overhead Sheets include TAKS released test items (grades 9Exit) to guide students through TAKS questions demonstrating this TEKS
Examples of TAKS connections include:
Lisa stayed to talk to her friends for about 5 minutes after school. Then she started to walk home. Halfway home she realized that she had forgotten her math book, so she ran back to school in half the time that she had already spent walking. Lisa took about 2 minutes to get her book and then walked home. She got home approximately 35 minutes after school was over. Which graph best represents this scenario?
V. Key Vocabulary
Slope
Rate of change
Increasing
Decreasing
Scale
Independent Variable
Dependent Variable

VII. follow up activities
The following TEKS would be good followups to this lesson:
A. 2(D) Collect and organize data, make and interpret scatterplots (including recognizing positive, negative, or no correlation for data approximating linear situations), and model, predict, and make decisions and critical judgments in problem situations.
