Pre-Test: Functions Mastery I
Enduring Understanding: Algebraic functions are represented in our world in a variety of contexts. Exploring these relationships will connect algebra to real world phenomena.
Purpose: The purpose of this lesson is to connect the real world of roller coasters to the algebraic functions that can be used to model them.
Value for the Student: The student will recognize how algebraic functions can model real world phenomena.

Thinking and Inquiry Strategies
Ask for input from class members on their roller coaster experiences.
Ask class members to describe what they saw in the first 3 segments of the Fury 325 ride.
Show students the 2nd video and ask for class members to identify algebraic functions they observe.
Tell students to break into their discussion/project groups.
IA-1.1 Communicate knowledge of algebraic relationships using mathematical terminology appropriately.
IA-1.3 Apply algebraic methods to solve problems in real world contexts.
IA-1.4 Judge the reasonableness of solutions.
IA-1.5 Understand algebraic relationships using a variety of representations, including verbal, graphical, numerical and symbolic.
IA-1.6 Understand how algebraic relationships can be represented in concrete models, pictorial models, and diagrams.
IA-1.7 Understand how to represent algebraic relationships using tools such as hand-held computing devices.
IA-2.10 Carry out a procedure to determine the domain and range of discontinuous functions, including piecewise functions.
IA-4.2 Carry out a procedure to determine specified points (including zeros, maximums and minimums) of polynomial functions.
The student will use knowledge of algebraic functions to sketch a graph of the pathway of the Fury 325 roller coaster, using reasonable values for zeros, domain, range, and extrema.
The student will use a graphing calculator and manipulate algebraic functions to create a model of the Fury 325.
The student will collaborate with group members to create a roller coaster and represent the roller coaster using a variety of models: pictorial, graphical, symbolic, and numeric.
The student will make a presentation of the roller coaster, using appropriate terminology and technology.
Classroom with video capability.
Classroom with group dynamics for discussion and graphing calculator work.
Computer lab for design and research.
Computer lab for creating the presentation, using a presentation tool (i,e, Prezi, PowerPoint, Animoto and Vuvox).
Classroom with technology, for project presentations.
The class, as a whole, will view the videos of the Fury 325 and students will share thoughts and ideas with the class.
The class will be divided into homogeneous groups for discussion, sketching and graphing calculator work.
Each group will design a roller coaster and create a presentation of the group findings.
Each group will present a project, with all members demonstrating participation.
Handout for graph sketching
Handout for calculator work

Computers with Internet access
The teacher will encourage class members to share thoughts and experiences of roller coaster rides.
Group discussions will help determine the best functions to represent the roller coaster pathway.
Calculator strategies will be discussed to construct an accurate, graphic model.
Teacher will act as a facilitator for group discussions and will answer questions and pose new questions, promoting deeper thinking.
Group members will carry out design and research, and select technology, based on the best outcome for the project.
Class members will be observers and questioners of the group presentations.
Teacher will pose questions after group presentations to assess understanding and to determine whether or not objectives are met.
Teacher will provide feedback and facilitate whole class discussions after presentations.
Students will use higher-degree functions (i.e. cubic and quartic) and non-functions (i.e. conic sections and parametric equations) to depict roller coaster pathways.
Students will focus on more complex roller coaster designs.
Students will use technology, other than graphing calculators (i.e. computer algebra systems), to create roller coaster pathways.
In addition to domain and range, students will add the parameter of time, when representing the roller coaster pathway.
Students will research the principles of physics inherent in roller coaster design and include their findings in the presentation.
Students will research and present other real world phenomena that can be modeled using algebraic functions.
Students will write a calculator program to determine specific graphic features, such as zeros and extrema.
Students will use technology to depict the graphic model of the roller coaster pathway in 3-dimensional, rather than 2-dimensional, format.
Students will build a 3-dimensional scale model of the group's roller coaster and present it to the class.
Lesson #3: Roller Coasters and the Paths They Take
Students will watch the 2 videos of the Fury 325 roller coaster and respond to teacher questions and contribute to the whole class discussion.
Students will work with group members to discuss, plan, and sketch the first 3 sections of the ride.
Students will discuss, create, and manipulate constant, linear and quadratic functions in the graphing calculator to create a calculator model of the first 3 sections of the ride.
Students will design a roller coaster, determine the piecewise defined function, and create multiple representations of the path.

Day 3 (one week after Day 1)
Students will present the final project to the class and answer questions from class members and the teacher, about the final project.
SMARTBoard technology for YouTube videos and project presentations
Graphing calculators for function manipulation
Graphing calculators for Gifted and Talented students to create programs
Computers, with Internet access, for design and research
Presentation tools and software, for projects
3-D computer software for Gifted and Talented students
Groups of students will use presentation software to create and present the results of their design and research.
If the design, research and presentation cannot be completed in one class period, group members must complete the assignment outside the classroom.
Presentations will begin 1 week after the viewing the YouTube videos, and will be in random order.
The presentation should be 3 - 5 minutes in length.
The question and answer session following the presentation will be monitored and managed by the teacher, for length and content.
All group members must participate in the presentation.
All group members must be able to accurately answer questions and provide feedback to class mates and to the teacher.
For whole class discussion after videos:
What functions do you recognize in the second video?
What features of the ride are we NOT considering in our scenario? Why?
For small group discussion:
What issues do you have creating your sketch, with respect to domain and range?
What algebraic manipulations did you find most helpful when working with the calculator?
What limitations do you find with your calculator?
For group presentations:
What functions would be impossible with regards to a roller coaster ride?
What functions would create a boring ride? a thrilling ride?
What other real world phenomena could be modeled by algebraic functions?
Consider the statement: Piecewise defined functions make better models for real world phenomena than single functions. Why?
Classmates will vote for the best design and the best presentation.
The teacher will address how other disciplines (with STEAM emphasis) relate to roller coaster design and ask for input from class members.
The teacher will share the following sites and encourage class members to explore the options.
Informal evaluation: observation and assessing answers to questions in group work.
Formal evaluation: Fury 325 graph and piecewise defined function, domain, range and scale.
Informal evaluation: Observation of group dynamics in computer lab.
Formal evaluation: Assessment of presentation and group participation using the rubric.
Ongoing evaluation: Depth of understanding judged by responses, and questions asked and answered.
Additional evaluation: products of exploration of coaster websites.
