Objectives This interactive learning object was designed for use in an Algebra class, and can be used as a stand alone, or more effectively in combination with classroom instruction. The material that is being taught is fairly complex, and so ample time should be given for students to process the information. The lessons do assume some previous knowledge of factoring and graphing quadratics, as well as basic techniques for solving equations. The objective of the lesson is for students to be able to solve quadratic equations by factoring, graphing, completing the square, and quadratic formula. References TEST Menu
