Lesson Plan for Junior Secondary 2 - Basic Tech - Angles Ii

### Lesson Plan: Angles II **Grade Level:** Junior Secondary 2 **Subject:** Basic Tech **Duration:** 60 minutes **Date:** [Insert Date] #### Lesson Objectives: By the end of the lesson, students will be able to: 1. Differentiate between types of angles including acute, obtuse, right, and straight angles. 2. Measure and draw angles using a protractor. 3. Apply the understanding of angles in basic technical drawings. #### Materials Needed: - Protractors - Rulers - Pencils - Whiteboard and markers - Angle chart (showing various types of angles) - Worksheets for practice #### Lesson Procedure: **Introduction (10 minutes)** 1. **Greet the Students:** Welcome them to the class and quickly recap the previous lesson on angles. 2. **Objective Introduction:** Briefly introduce the objectives of the lesson. Explain why understanding angles is important in Basic Tech and everyday life. **Direct Instruction (15 minutes)** 1. **Different Types of Angles:** - **Acute Angle:** Less than 90 degrees. - **Right Angle:** Exactly 90 degrees. - **Obtuse Angle:** More than 90 degrees but less than 180 degrees. - **Straight Angle:** Exactly 180 degrees. Use the whiteboard to draw and label each type of angle. Discuss real-life examples where these angles are found. 2. **Using a Protractor:** - Demonstrate how to measure angles using a protractor. - Show the students how to align the protractor correctly and read the measurement. **Guided Practice (15 minutes)** 1. **Hands-On Measuring:** - Hand out protractors, rulers, and pencils. - Guide students through measuring given angles on a worksheet. 2. **Drawing Angles:** - Demonstrate drawing a variety of angles. - Instruct students to draw different angles that you call out (e.g., 45 degrees, 90 degrees, 135 degrees). **Independent Practice (15 minutes)** 1. **Worksheet Completion:** - Provide students with worksheets that include various exercises on identifying and measuring different types of angles. **Assessment (5 minutes)** 1. **Quick Quiz:** - A five-question quiz to assess students' understanding. - Questions will include identifying angles in diagrams and measuring or drawing specific angles. **Closing (5 minutes)** 1. **Review and Recap:** - Quickly go over the key points of the lesson. - Address any questions or clarifications needed. 2. **Homework Assignment:** - Assign a homework task where students must find and label angles in their home environment (e.g., corners of rooms, furniture) and bring their observations to the next class. 3. **Announcements and Dismissal:** - Inform students of the next lesson's topic and dismiss the class. #### Reflection: - Note what worked well and what could be improved for future lessons. - Reflect on student engagement and comprehension levels. --- **Teacher's Notes:** - Ensure to walk around the class to assist students during hands-on activities. - Encourage students to ask questions if they are unclear about any concept. - Use visual aids like angle charts to reinforce learning visually.
