**Lesson Plan** **Topic:** Angle Bisectors **Class:** VI **Subject:** Mathematics **Duration:** 50 minutes **Competency**: Demonstrate the ability to identify angle bisector in the immediate surroundings. **Strand**: Geometry **Lesson Objectives:** By the end of the lesson each child will be able to: - Recognize and describe angle bisectors. - Bisect angles using a protector. **Lesson Introduction (5 minutes)** **Recap Previous Lesson:** - Begin by asking students to draw a 60-degree angle. - Ask them to divide the angle into two equal parts. - Explain that the line which divides the angle into two equal parts is called an angle bisector. **Introduce the Topic:** Inform students that today's lesson will focus on angle bisectors. **Lesson Development (40 minutes)** **Naming Angles:** - Explain how angles are named using their vertices and the angle symbol (e.g., ∠ABC). - Provide examples and ask students to name angles. **Identifying Angle Bisectors:** - Demonstrate how to identify angle bisectors using a protractor. Guide students through the process of bisecting angles step-by-step: - Draw an angle (e.g., 60 degrees). - Place the protractor on the 00angle and mark the midpoint. - Draw a line from the vertex to the midpoint to create the angle bisector. **Practice:** - Allow students to practice bisecting different angles on their worksheets. - Walk around the classroom to provide assistance and ensure students are following the steps correctly. **Lesson Closure (5 minutes)** - Summarize the concepts discussed during the lesson (angle bisectors). Let a few volunteers share on how to identify the angle bisectors and bisect angles. - Provide homework to identify angle bisectors and bisect angles.
