Author: Chicago Teachers Union Quest Center

• Description
• Files

Mathematically:

• Addresses standards F-IF.B.4 and F-IF.C.7
• Promotes coherence by highlighting prior knowledge and pointing to the mathematics that will be built from these ideas
• Develops students' understanding of zeros and other key features from the factored form of a quadratic function (F-IF.B.4)
• Requires students to analyze and see the connection between quadratic functions represented graphically and algebraically
• Requires students' use of precise course-appropriate mathematical language (MP.6)

In the classroom:

• Offers an engaging activity that connects students' procedural skill and conceptual understanding of the key features of a quadratic function
• Allows for whole group, partner, and individual work in one lesson
• Provides entry points for student discussion through suggested dialogue for teachers
• Encourages students to share their developing thinking
• Uses explanations and representations to make the mathematics of the lesson explicit

• Making the Shifts

How does this lesson exemplify the instructional Shifts required by CCSSM?

 Focus Belongs to the Widely Applicable Prerequisites for College and Careers Coherence Builds on many key understandings from grade 8, expanding from linear to quadratic functions, and specifically calls out how this lesson falls within the progression of learning Rigor Conceptual Understanding: primary in this lesson (F-IF.B.4) Procedural Skill and Fluency: primary in this lesson (F-IF.C.7) Application: not addressed in this lesson
