Ch 9: Quadratics
Ch 9: Quadratics
Standards: 1d, 2d, 5a, 5b, 5c
Pacing: Approx. 20 days
9-1: Identifying Quadratic Functions 2 days -b/2a out of place
-Lesson is pretty basic.
-Good Exploration
9-2: Characteristics of Quadratic Functions 3 days
-Begin with Reaching All Learners on p. 600
-9-2 Algebra Lab, p. 598, is a good warm-up for the lesson, but it is optional
-Skip the Exploration
-Think and Discuss, p. 603, is good
-9-2 Challenge is really good, but is likely only for the accelerated kids
Quiz on 9-1 & 9-2 be sure they can graph by hand before they use calculators
9-3: Graphing Quadratic Functions 2 days
-Will take two days of class and could be broken into Day 1 – Graphing & Day – 2 Problem Solving
-Practice B worksheet is good for an assignment
9-4: Transforming Quadratic Functions 3 days use calculators to enhance
-9-4 Tech Lab, p. 612, and Exploration are very good (use of graphing calculator) and pretty much covers everything in the whole lesson (except Ex. 3)
-Think and Discuss, p. 616, is very good. Graphic organizer is a good way to summarize the transformations.
9-5: Solving Quadratic Equations by Graphing
Skip this lesson
Quiz on 9-3 to 9-4
9-6: Solving Quadratic Equations by Factoring 3 days
-Introduce Standard Form of a Quadratic Equation
-Exploration is good (can have them hand-graph it or use the graphing calculator)
9-7: Solving Quadratic Equations by Using Square Roots 2 days
-Exploration is excellent
-Approach from a very basic level
9-6 to 9-7 Quiz
p. 643 Geometry Connection – Distance Formula – SKIP THIS
9-8: Algebra Lab – Model of Completing the Square with tiles – do it if you want to 5 days
9-8: Completing the Square
-Begin the lesson with the Exploration & Motivate (p. 645)
-Think and Discuss, p. 648, has a really good graphic organizer (see p. A8 to show how it should look)
9-9: The Quadratic Formula and the Discriminate
-Exploration is good, but may want to do it after walking through the proof on p. 652 and giving the quadratic formula
-Motivate, p. 652, shows that solutions are not always integers and that the Quadratic Formula can always be used to find exact solutions
-Good summary of Methods to Solve Quadratic Equations on p. 656
-Good graphic organizer on Reading Strategies worksheet
