This is a detailed lesson plan that focuses on using the discriminant to determine the nature of the roots of a quadratic equation. The lesson plan begins with learners investigating similarities and differences among graphs of four quadratic equations. After discussing their findings, they work in groups to complete exercises designed to develop the connections between the value of the discriminant of an equation, the nature of its roots, and the number of x-intercepts of its graph. The resource includes a good number of follow-up exercises to help solidify concepts. It also includes two optional PowerPoint presentations.

Students write sentences defining a fair classroom, a fair school, and a fair society. Students write letters to restaurant owners about discrimination of employees.
Defining the word "discriminant" in the context of the quadratic formula, Sal continues to guide viewers through the process of quadratic equations. The true value of this video, as in Sal's entire series, is the emphasis on truly understanding the mathematical process necessary to solve the problem. Sal wants to foster a deeper learning within young mathematicians, rather than just handing them a formula and telling them to use it.
Stereotyping and discrimination are explored in this social justice lesson plan. Students listen to the book Dragon of Brog, in which mythical characters experience discrimination. Then, they sculpt a magical character out of plasticene and write a related description of this character.
