Miniature Golf Project

• Your group represents a golf course design and construction company

• There will be 6 members per group with the following responsibilities– Course Designer– Consulting– Hole Designer– Accounting– Marketing– Technical Support

Course Designer• Make nine holes on Geometer’s Sketchpad, each as a separate

sketch– Find area, perimeter, and direct distance to hole for each one

• Be sure not to count interior edges between different areas

– Use color– “Pocket” diameter is 3in., but you can use a point in the sketch– Show the scale for each hole– Assume all holes are flat

• Make overall course map showing all holes– Use dilations and reflections to put all holes together– Show the scale used– Don’t worry about area between holes (or cost of constructing that area)

Consulting

• List geometry standards used in making of course• Work alongside course designer to show hole-in-

one route with a dotted line– Adjust hole shape if necessary– You should always make it possible to get a hole-in-

one– Use reflections

• Decide on realistic par for each hole (at least 2)

Sample Hole 1

• Area (with “pocket”) = 32.27 sq.ft• Perimeter = 35.91ft• Distance = 10.58ft• Par 2

Sample Hole 2

• Area (with “pocket”) = 33.62 sq.ft

• Perimeter = 43.89ft• Distance = 8.95ft• Par 2

Sample Hole 3

• Area (w/“pocket”, w/o bumpers) = 21.35 sq.ft

• Perimeter (w/bumper edges) = 40.59ft

• Distance = 8.78ft• Par 3

Sample course layout

• Uses sample holes 2,3• Use rotations and

dilations

Hole Designer

• Make a scale model of a single hole

• Use a shoe box, wood, styrofoam, whatever works best

• Calculate area and perimeter using geometric formulae (not using GSP)

• Indicate the scale

Accounting

• You will need to come up with the costs of construction using the following data (and ignoring labor, etc.)– Turf:$1.25/sq.ft– Trim around hole,bumpers: $0.25/ft.– Cement bumpers:$2.50/sq.ft– “Pocket”:$5 each

• Calculate the following:– Costs for each hole– Cost for each material– Total costs

Marketing

• Decide on a company name, a golf course name, and golf course theme

• Design advertising and/or other information

• Design the score card, listing par and direct length for each hole

• List course rules and costs to play

• Lead the presentation of your group

Technical Support

• Put all Geometer’s Sketchpad, Excel, and all other documents from your group members into a PowerPoint/MacWorks presentation– Make it look good!

• Explain all the geometry used in the design of the course

Assessment• Each group is responsible for a PowerPoint presentation, a

copy for me on diskette of your presentation, and a scale model of a hole; I’m not collecting anything else

• Every group member gets the same grade, except for obvious exceptions

• If you think you’re done with your job, help someone else in your group!

• Each individual grade (for each job) will be a score from 1 to 10, then all of it scaled to 100

• This project is worth 2.5% of your grade• You will have 4 days of computer room time, with

presentations on the last half of the 4th day– GET ORGANIZED ASAP
