 * Lesson Plan Template **
 * For 21st Century Educators ** ** Springfield **** High School **


 * Date:_ __Period(s):__ April 19, 2010 (4th period, Advanced Algebra - 8th & 9th graders) **


 * Standard/Performance Indicator: Patterns, Functions and Algebra Standard **


 * Instructional Objective: Students will be able to solve quadratic equations with real roots by factoring graphing, using the quadratic formula and with technology. **


 * Teaching Strategy: Teacher will use TI-84 (or comparable graphing calculator) to demonstrate the graphing of a quadratic function. Teacher will also circulate about the room as students complete their group activity. **


 * Student Activity: Students will work in groups of 3 or 4. At least one student in each group will have a TI-84 (or comparable graphing calculator). Each group will be assigned a quadratic equation. The group will collectively solve (with 90% accuracy) the equation by completing the square, finding the roots of the equation, and subsequently graphing it on their calculator. After the group has agreed on a solution, the group will bring their calculator (showing the graph) to the ELMO. The groups will be responsible for showing their graph and explaining their solution to the rest of the class. **


 * Materials Required: A worksheet listing 10-12 problems, a minimum of one graphing calculator per group, as well as one for the teacher, an ELMO, a projector, and a projection screen. **


 * Evaluation: Each group's solution will be evaluated by the members of other groups, as well as the teacher. **


 * Extension/Homework: For homework, students will complete any problems on the worksheet (with 80% accuracy) that were not completed by groups in class. **
