**Lesson Outline:**
**Introduction (10 minutes)**
1. **Greeting and Settling Down** (2 minutes)
- Welcome students and ensure they’re seated comfortably.
2. **Introduction to Topic** (3 minutes)
- Briefly introduce the topic and explain the importance of accurate marking out and measuring in metalwork.
3. **Learning Objectives** (2 minutes)
- Share the objectives of the lesson with the students.
4. **Hook/Engagement Question** (3 minutes)
- Ask the students: "Why do you think measuring and marking out accurately is important in metalwork?"
**Instructional Phase (20 minutes)**
1. **Presentation of Tools** (10 minutes)
