Title:

Investigating School Safety and Slope

Overview/Annotation:

Using a 'news report' approach, students investigate the slope of various stairways on the school campus and report on wheelchair accessibility and adherence to the Americans with Disabilities Act. (PowerPoint Included) An extension of this lesson includes the critique/design of existing/nonexistent ramps.
This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

 Associated Standards and Objectives 
Content Standard(s):
Mathematics
MA2015 (2016)
Grade: 8
14 ) Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x,y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of linear function in terms of the situation it models and in terms of its graph or a table of values. [8-F4]


NAEP Framework
NAEP Statement::
8A1c: Analyze or create patterns, sequences, or linear functions given a rule.



Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.8.14- Given a graph of a function, determine if it is linear and identify the y-intercept.
M.AAS.8.14a - Count out the rise over the run of a line on a graph to show the change from point to point on a line


Mathematics
MA2015 (2016)
Grade: 9-12
Algebra I
30 ) Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.* [F-IF6]


Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.F.HS.30- Given two points on the graph of the line, describe how the y-values change compared to the x- values for a given interval.


Mathematics
MA2015 (2016)
Grade: 9-12
Algebra I
46 ) Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data. [S-ID7]


Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.SP.HS.46- Given a graph that describes a set of linear data, identify the rate of change (slope) and constant term (y-intercept). (Use context of data—the total price of the stamps is calculated by increasing 50 cents for every stamp purchased or the cost if no stamps are purchased is $0.)


Mathematics
MA2015 (2016)
Grade: 9-12
Algebraic Connections
1 ) Create algebraic models for application-based problems by developing and solving equations and inequalities, including those involving direct, inverse, and joint variation. (Alabama)

Example: The amount of sales tax on a new car is directly proportional to the purchase price of the car. If the sales tax on a $20,500 car is $1,600, what is the purchase price of a new car that has a sales tax of $3,200'

                Answer: The purchase price of the new car is $41,000.

Primary Learning Objective(s):

The student will demonstrate and explain their understanding of applied slope through a video demonstration.

Additional Learning Objective(s):

The student will critique and/or modify existing (or non-existing) ramps in the school to meet the Americans with Disabilities Act. (Extended Lesson)

 Preparation Information 

Total Duration:

91 to 120 Minutes

Materials and Resources:

PowerPoint* (included), Project Handout (included), Grade Rubric (included), Tape Measures (or Yardstick and String), Pencils, Paper, Additional Practice Problems, SEE TECHNOLOGY EQUIPMENT NEEDS

Technology Resources Needed:

Presentation Equipment for PowerPoint* *Computer *Projector Digital Video and/or Video Camera's** VCR and/or Playback equipment **Digital Camera can be substituted / Grade Rubric and Assignment should be altered accordingly (See Accomodation)

Background/Preparation:

Slope and Slope Formula Review Powerpoint (included) Print 'Notes Copy' of PowerPoint Copy Project Assignment and Rubric Americans with Disabilities Act (in Powerpoint)

  Procedures/Activities: 
1.)Review the Powerpoint prior to showing in class. Print a copy of the 'Notes Pages' to use during your discussion, it will provide answers to problems and warn you of 'fly-in' items.

2.)Have additional problems available for calculating slope when given 2 points. You will need these during the PowerPoint for additional practice and/or homework.

3.)Gather materials needed for the 'Reporting on Slope in our School' Assignment (see supply list).

4.)With students: discuss/reiterate the concept of slope and then present the PowerPoint on 'Slope in our Society'
(ADA Accessibility Guidelines for Buildings and Facilities (ADAAG))
The link to this website is also included in the PowerPoint. It is used on slide 8.

5.)Explain the assignment using the hand-out. Allow students time to investigate the Americans with Disabilities Act on the internet (or provide them the information needed).

6.)Discuss expected behavior around the school grounds and pass out required equipment.

7.)Walk with students and help them as they complete their assignment of 'Reporting on slope in our school'.

8.)Return to class and allow time for students to choose their best presentation.

9.)Assess students knowledge of slope as you watch each presentation. Grades can be given for accuracy on their worksheet and/or their professionalism in the presentation. See Rubric.

10.)If you finish early, students can view changes in the slope of a line using the Shodor.org applet. This is an EXCELLENT resource to introduce y=mx+b later in the semester.
(Slope Slider computer applet)
A computer applet (interactive program) that allows students to change the slope / y-intercept of a line and see the change.

  Assessment  

Assessment Strategies

Assessment occurs at the following times: -Ongoing during PowerPoint presentation -Additional Practice Problems -Project (grade rubric included)

Acceleration:

Students can modify (or design a ramp where one is nonexistent) to meet the code of the Americans with Disabilities Act.

Intervention:

Students in need of extra assistance may need review on the following: (a)order of operations (b)identifying points (x,y) on a coordinate plane (c)slope basics (included in PowerPoint)
