This lesson is designed as a review lesson for solving quadratic equations. Students will play the game "Chutes and Ladders," modified for quadratic equations, as they review for the test.
Elementary Algebra is a work text that covers the traditional topics studied in a modern elementary algebra course. It is intended for students who (1) have no exposure to elementary algebra, (2) have previously had an unpleasant experience with elementary algebra, or (3) need to review algebraic concepts and techniques.
This lesson will help students quickly graph a quadratic equation. It will also help them to understand the purpose of completing the square.
This plan uses student created Hyperstudio Programs to present, review, and summarize various methods of solving quadratic equations.
This is the answer page for the Optimization of a Function Module. The student will write and graph linear functions then use these functions to write a new function using the Pythagorean Theorem.
This module discusses the different types of solutions to quadratic equations.
This module discusses how to solve quadratic equations by factoring.
This module covers the graphing of quadratic equations.
This module teaches about multiplying binomials. Specifically about common patterns that can be memorized and using the "FOIL" method.
This module covers quadratic inequalities.
This module covers how to solve problems through the graphic of quadratic functions.
This module teaches the method of solving quadratic equations by completing the square.
This module teaches the method of solving quadratic equations by factoring.
This module discusses the quadratic formula.
An interactive applet that allows the user to graphically explore the properties of a quadratic equation. Specifically, it is designed to foster an intuitive understanding of the effects of changing the three coefficients in the function. The applet shows a large graph of a quadratic (ax^2 + bx +c) and has three slider controls, one each for the coefficients a,b and c. As the sliders are moved, the graph is redrawn in real time illustrating the effects of these variations. The roots of the equation are shown both graphically and numerically, including the case where the roots are imaginary. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
The objective for this lesson is for students to investigate vertical translations on a quadratic function while reviewing quadratic functions.
This is the teacher's page for the Translating a Quadratic Functions Module.
