### Lesson Plan: Basic Tech for Junior Secondary 2
#### Topic: Understanding Angles
---
#### Objective:
By the end of the lesson, students will be able to:
1. Define an angle
2. Identify types of angles (acute, right, obtuse, straight, reflex)
3. Measure and draw angles using a protractor
#### Materials Needed:
- Whiteboard and markers
- Protractors for each student
- Rulers
- Angles Worksheet
- Angle Flashcards
- Learning Management System (LMS) access for interactive exercises (optional)
#### Time: 40 minutes

### Lesson Structure:
#### Introduction (5 minutes):
1. **Greet students and take attendance.**
2. **Introduction to Angles**:
- Briefly discuss what an angle is: "An angle is formed by two rays with a common endpoint called the vertex."
- Show examples using your arms or using two rulers.
#### Direct Instruction (10 minutes):
1. **Types of Angles:**
- Use the whiteboard and draw different types of angles.
- **Acute Angle**: Less than 90 degrees.
- **Right Angle**: Exactly 90 degrees.
- **Obtuse Angle**: Between 90 and 180 degrees.
- **Straight Angle**: Exactly 180 degrees.
- **Reflex Angle**: Between 180 and 360 degrees.
- As you draw each type, label and describe them.
2. **Tools for measuring angles**:
- Explain how a protractor works.
- Demonstrate measuring an angle on the whiteboard.
#### Guided Practice (10 minutes):
1. **Hands-On Activity**:
- Hand out protractors and rulers to students.
- Distribute the Angles Worksheet.
- Guide students through measuring angles on the worksheet, step-by-step.
- Circulate the room to provide support and feedback.
#### Independent Practice (10 minutes):
1. **Drawing Angles**:
- Ask students to draw their own angles using a protractor and ruler.
- They should label the type of angle they drew.
- Encourage students to draw at least one example of each type of angle.
#### Closure (5 minutes):
1. **Review and Recap**:
- Ask students to name the different types of angles and their properties.
- Quickly review how to measure an angle with a protractor.
- Address any final questions.
#### Assessment:
- Collect and review worksheets for accuracy.
- Oral questioning during the review phase.
- Observe students during hands-on practice to ensure they understand the correct methods.

### Homework:
1. **Worksheet**: Distribute an additional worksheet with angle identification and measurement exercises to be completed at home.
2. **Interactive Exercise**: If accessible, students can log into the LMS to complete an interactive quiz on angles.

### Differentiation:
- **Advanced Students**: Provide more complex angle problems or introduce the concept of complementary and supplementary angles.
- **Struggling Students**: Offer one-on-one support during the guided practice or pair them with a peer helper.
- **Visual Learners**: Use colorful diagrams and angle flashcards.
- **Kinesthetic Learners**: Allow opportunities for creating angles with physical objects like rulers or string.
This lesson plan provides a mix of direct instruction, guided practice, and independent work to cater to different learning styles and ensure that students understand the basic concepts of angles.
