About This Lesson
This 50-minute lesson introduces quadratic functions and their graphs. Students learn the standard form y = ax^2 + bx + c and the vertex form y = a(x - h)^2 + k, identify parabolas, and analyze key features including the vertex, axis of symmetry, and intercepts. Worked examples build tables of values, graph a basic parabola, shift and stretch a parabola, and model the height of a thrown ball. The lesson plan includes objectives, prerequisite skills, key vocabulary with definition cards and short definition videos, three warm-up activities (algebra tiles, areas of rectangles with variable dimensions, and graphing in Desmos), a captioned tutorial video, a review with two more examples, a 10-question quiz, and an answer key.
