The Big Idea (including global relevance)

Rebuilding a Physical Activity Center after disaster strikes.

Disasters are happening all around us no matter what area we live in.  Fires in residential areas leave people homeless.  Fires in buildings leave people with no jobs.  A fire has also left students with no place for one of their greatest joys, playing sports.  Architects and contractors are in high demand when disasters happen and call for a rebuild, the only problem is the cost of hiring experts. 

The Essential Question

How can the design of a gymnasium affect the cost?

What variables go into the cost of a gymnasium?

How is the size of a basketball court determined?

What percentage of the space is restrooms, open gym space, hallways, bleachers, etc?

How high….

Justification for Selection of Content

Students sometimes find it difficult to derive equations associated with patterns.  In this case students will work through problems about geometric and arithmetic sequences and develop equations that can be used to estimate much larger numbers.  Students fail to understand that equations make situations much easier and faster than computing by hand.  Students also struggle with making connections between graphs, tables and equations.  After finding patterns and creating an equations students will use excel to compute all of the hard calculations and for creating the graphs.  Students will begin to see the real world application of graphs and how data is used in many companies.  Students need to have comfort in using excel as a handy tool rather than be scared. 

The Challenge

A disaster has struck over the holidays totally destroying our gym.  This disaster has left us with no space for gym class or Friday night basketball games. The board has decided to allow you to design the new gym (with locker rooms) so more money will be in the budget for the rebuild rather than paying a hefty fee for an architect to design your gym. 

How will you use the variables of construction to design a new gymnasium and locker rooms for your school?

The Hook

A quick clip of a newly designed gym and locker room.  These videos will be combined and I will add audio to make it more appealing to my students.

Ask students two questions after video and hold a 5 minute discussion.  These questions should get students to start thinking about changes that can be made after given the opportunity to design their school’s new gymnasium.

Q1: What do you like about gym class?

Q2: What do you not like about gym class?

Real World Applications

Students will learn how to develop equations for determining the amount of square footage a building can use.  Students will design the layout which will help them conceptualize space and functionality (certain designs are done for a reason) keeping scale factors in mind.

Career Connections

Interpreting graphs and being able to provide valid reasons using math is helpfully for everyone

in society. Being able to use equations to determine how much a building would cost or being able to determine the maximum number of square feet needed for a certain budget.  You can also determine length of payments on a mortgage.

Architects, contractors and architectural and mechanical engineers would be the careers associated with this challenge.

Societal Impact

Individuals need to understand the concept of cost and ways to maximize space in work areas.  This will help in building future homes as well as bigger facilitates. Many individuals struggle with the concept of organization.  Designing a space that must maximize space is a great way of using organization, not only to organize your notes in school, but your files in an office, your files on your computer or your equipment for sports games. 

Engineering Design Process (EDP)

Challenge – Students will have to design a gym and locker rooms for their school given a workspace and determining the equations associated with initial costs and the additional variable costs.                               

Research – Students will use websites to find useful data for designing their space; for example, what are the dimensions of a high school basketball court?,  What are the dimensions of where the tape should be placed for out of bound lines?,  What variables would add cost to the final project? What percentage of the gym is used for seating?  How many people on average attend Friday night games? How many of those people are men/women?  How many restrooms are needed?  Will there need to be more stalls in the men’s or women’s restrooms?  Etc.

Brainstorm and Essential Questions – Students will use their background knowledge in addition to the math concepts gained from the activity and apply to calculate the cost for a certain size building as well as the area of the space needed. 

Build – A paper sketch drawing that shows the gym space, locker room space, and dimensions.  Use excel to calculate the cost of different size buildings with the different amounts of restrooms, tiles, lockers, bleachers and so on, using equations, charts, graphs on Microsoft Excel.

Redesign – After each group presents their findings on the costs of their portion of the construction including the arithmetic/geometric sequence; each group will then take all research into consideration when finalizing their design.   

Final Conclusion – Students will give a presentation that must show and explain all of their findings in the fashion of a pitch/sale.  Students will present in front of the individuals who have the final say decision in the design of the new 2015 Hughes STEM High School Gymnasium with locker rooms; therefore, students must convince the board to choose their design based on the numbers that make their design work.

Unit Activities

Lesson 1: Introduction to the components of Challenge Based Learning

Hook plus PowerPoint introduction (1 class period, 55 min); Pre-assessment (30 min)

Students will watch the video of one of the best gyms and locker rooms.  Students will answer questions and class will hold a quick discussion.  Students will take a pre - assessment that will provide a way to gather key information about what students know and are able to do prior to instruction.  We will then move into the introduction PowerPoint that focuses on the big idea, essential questions, and guiding questions and finally I will present the challenge. 

Activity 1:  Hook- A combination of two videos will be shown and two questions will be posted.  Students will have 5 minutes to individually answer the questions and then the class will have a quick discussion.

Activity 2:  Pre-Assessment- Students will take a pre assessment to gather data about what students know prior to the lesson.  Data will be recorded for further use.

Activity 3:  PowerPoint Introduction -The big idea will be introduced to the students.  I will ask students to think of two essential questions that relate to the big idea (3 min).  We will share out as a class and I will chart the responses on the board.  Once I guide the class to the essential question I have in mind we will start brainstorming ideas for guiding questions.  Each student must brainstorm at least 4 guiding questions individually (5 min) and we will share out and chart in the same fashion as for the essential question.

Lesson 2: Determine variable costs and derive equations.(4 bells)

Students will work through an activity to develop an understanding of the extra costs associated with certain materials.  Students will be placed in groups of three and will use the Engineering Design Process to begin solving their challenge.  Students will present their findings to the entire class and other groups will choose to use the information provided or decide to change some parts depending on their research and their specific design.      

Activity 4: Construction Cost of Tiles (1 bell, 55 min)

Students will use given dimensions of an area to calculate the number of tiles needed to tile the area, as well as, the number of boxes of tile, the total cost of the area and the cost per square foot of tiled area.  Students will have to research how the cost of this room could be decreased.

Activity 5:  Groupings with given variables ( 3 bells, 165 total min)

Students are grouped and given a specific variable to research.  Students will start to develop an understanding of cost variances dependent on the change of materials as they research prices for restrooms, hallways, lockers, showers, basketball court, storage closets, bleachers/seating, sinks, entrance, and stairs; as well as, researching the percentage of gymnasiums that are restrooms, bleachers, walls, etc.   (List might change depending on discussion with students)  Once research is complete students will present their findings with the class.  Each group will take the research their classmates discovered and use them to finalize their design including formulas of percentages and costs of specific rooms in addition to the entire gym.  Students will present their final findings in an Excel spreadsheet including: equations, cost, data tables, graphs and percentages of specific areas of the design.  Students will need to present understanding of information included in their excel document.  Each student will need to have a part on speaking during the presentation.

Misconceptions

Knowledge that all sequences are not arithmetic but when asked to give examples they can only give arithmetic examples.

Sequences only containing whole positive numbers.
