What we like about this lesson

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
