5- Day Lesson Plan Unit: Linear Equations Grade Level: Grade 9 ...

33Lecture/Activities:1. The teacher will go through on the overhead how to use the matrixprogram in the TI-83 plus calculator. (Instructional Worksheet)2. The students will follow with the teacher on how to solve a systemequation in the matrix program as the teacher demonstrates with thecalculator on the overhead. Each student will have a copy of theInstructional worksheet for a reference.3. The teacher will also go through graphing the two linear equations onthe calculator as a way to check their answers by finding theintersection.4. The students will be given a worksheet of different system ofequations, where they will need to work independently to solve theequations. (Worksheet)5. When the students are finished with their worksheet they will get intogroups of 3 and compare answers.6. In their groups they will answer a few thinking questions that are onthe handout.7. When all the groups are finished discussing their answers and groupquestions, the class will come together and the teacher will have aclass discussion on the problems they have been working on.Closure: The students will write into their journals about the lesson. They will writedown something they learned and something they are still confused about in regards tothe lesson.Assessment: The students will be given a homework assignment of many systems ofequations.
