### 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.
