Pre-Algebra B

How can learning algebra and data analysis help me build a business that solves real life problems and creates value in my society?

Pre-Algebra bridges the gap between arthimetic and algebra.

Why Take This Course?

Have you ever wanted to start your own business? As we will learn with Fred (from the Life of Fred series), we’re all in business! Join us as we push past misconceptions that “only some people can do math” and connect mathematical concepts to the real-life experience of building a business.

In this course, students will continue applying Algebra to represent the real world. Students will learn how to easily determine solutions to multi-variable real-world situations and explore the connections between various representations and characteristics of linear functions. Other topics include making inferences based on data analysis of trends, and using algebra and graphing to solve for solutions. This High School Math course includes an emphasis on having a growth mindset towards math, with an engaging midterm that helps students see the fun and fascinating side of mathematics.

Expedition: Build a Business

The Build a Business expedition is a great follow-up after students successfully interviewed for a job last semester. Students will first explore the context of manufacturing, mastering the understanding of linear concepts such as slope and intercept. Students will then focus on marketing, in which they will use bivariate data to create advertisements for the ideal client. Finally, students will work in actuarial finance where they will solve systems of linear equations by both graphing and algebra. By the end of the semester, students will understand marketing strategies, manufacturing techniques, and will be able to make sound financial decisions. The Build a Business expedition will be complete with a Summit Project in which students submit their own business proposal.

Course Framework
