One day in 2580 B.C.E., a very serious architect stood in a dusty desert with a set of plans. His plans called for creating a structure 480 feet tall, with a square base and triangular sides, using stone blocks weighing two tons each. The Pharaoh wanted the job done right. The better this architect understood geometry, the better his chances were for staying alive.

Geometry is everywhere, not just in pyramids. Engineers use geometry to build highways and bridges. Artists use geometry to create perspective in their paintings, and mapmakers help travelers find things using the points located on a geometric grid. Throughout this course, students travel a mathematical highway illuminated by spatial relationships, reasoning, connections, and problem-solving.

Projects allow students to demonstrate competence and understanding of concepts and skills by completing a career-related task. For example, the assignment might be to create a mural, a package design, a speech, a film review, or a movie set – you name it! These creative projects are about applying your learning acquired through in-depth research to real-world career tasks.

Each competency will be addressed through a project that is based on a real-life career task. Here are the careers you will explore: Gemologist, Building Inspector, Textile Designer, Transportation Planner, Irrigation Design Engineer, Package Designer, Surveyor, and Carpenter.

### Projects

##### Gemologist

You will take on the role of a gemologist at a jewelry firm, tasked with creating a diamond appraisal report for a customer, describing the grade and cuts.

##### Textile Designer

You will take on the role of a textile designer working for a fashion designer, tasked with creating a portfolio with frieze patterns that preserve angles and keep lengths in proportion for all dilations.

##### Transportation Planner

You will take on the role of a transportation planner for a delivery company, tasked with creating a plan for delivery routes.

##### Irrigation Design Engineer

You will take on the role of an irrigation design engineer hired by a farmer to design an irrigation system for his crop field. It is your job to design a system using circular sprinklers that waters the most amount of land without double watering or leaving un-watered areas.

##### Package Designer

You will take on the role of a package designer working for a sports company, tasked with creating a presentation of your package designs.

##### Surveyor

You will take on the role of a surveyor, tasked with creating a report to settle a dispute. Using the landowner’s land deed to diagram the land, you will compute the acreage of the land and write a conclusion.

##### Carpenter

You will take on the role of an apprentice for a carpenter, tasked with creating a design for a customer’s new kitchen cabinet.

Experiences allow you to explore a career field you’re curious about while mastering competencies for school credit. Through experiential learning, you will learn skills and apply them to tasks you would complete as part of a career rather than completing traditional assessments like essays or tests. During your Experience, you’ll work with a professional in the field to support your learning whom we call a “mentor.” You’ll earn a badge for your accomplishments to share on social media and higher education platforms, or with colleges, potential employers, peers, and colleagues to display your qualifications.

Here’s how Experiences work:

• Each competency you work on is addressed through a separate deliverable predetermined by you and your instructor.
• Guided learning for each module consists of research and/or work with a professional in the field. Your instructor will coach you through this process.
• Each module culminates in a final demonstration of understanding, which includes a deliverable and a discussion-based assessment with your instructor.
• Here’s an example:

Obtaining a Mentor: Prior to enrollment, please have an idea for a mentor in mind. We have partnered with hundreds of mentors you can work with during your Experience, who you can find in our Career Mentor Catalog here. Or, you may consult with our counseling department by emailing [email protected] for help in identifying one.

*A parent/guardian permission form and background check of the mentor are both required to work with mentors without parental supervision.
