#### Lesson Outline:
**Introduction (10 minutes)**
1. **Review:** Briefly review basic spreadsheet concepts covered in previous lessons (e.g., cell referencing, basic formulas like SUM and AVERAGE).
2. **Objective Introduction:** Introduce today's lesson with an overview of advanced functions, chart creation, and conditional formatting.
---
**Instruction and Demonstration (20 minutes)**
1. **Advanced Functions and Formulas (10 minutes):**
- Demonstrate the use of advanced functions like VLOOKUP, HLOOKUP, IF, and nested IF statements.
- Show how to combine functions to solve complex problems (e.g., IF combined with AND/OR).
2. **Charts (7 minutes):**
- Demonstrate how to create different types of charts (bar, line, pie) to represent data.
- Explain the importance of selecting the appropriate chart type for the dataset.
3. **Conditional Formatting (3 minutes):**
- Show how to use conditional formatting to highlight cells based on certain criteria (e.g., values greater than a certain amount, duplicates).
---
**Guided Practice (20 minutes)**
1. **Advanced Functions Practice (10 minutes):**
- Distribute pre-prepared spreadsheet files.
- Guide students through an exercise involving advanced functions such as VLOOKUP and nested IF statements.
- Walk around the classroom to provide individual assistance.
2. **Charts Creation (5 minutes):**
- Provide a dataset and guide students in creating a bar chart and a pie chart.
- Ensure students understand how to label and format charts properly.
3. **Conditional Formatting Exercise (5 minutes):**
- Have students apply conditional formatting to a set of data to highlight specific information (e.g., sales figures above targets).
---
**Independent Practice (10 minutes)**
- Assign a task where students will use a new dataset to create a summary report involving:
1. Advanced functions (such as a VLOOKUP table).
2. A relevant chart.
3. Conditional formatting to highlight key information.
- Encourage students to complete the task independently, offering assistance as required.
---
**Conclusion and Q&A (5 minutes)**
1. **Recap:** Summarize key points discussed in the lesson.
2. **Q&A Session:** Provide time for students to ask questions and clarify any doubts.
3. **Assignment:** Assign a take-home task where students create a budget sheet involving the advanced functions, chart types, and conditional formatting learned.
---
**Assessment:**
- Monitor students during guided and independent practice to ensure understanding.
- Evaluate the take-home assignment for correct application of advanced functions, charts, and conditional formatting.
---
**Homework:**
Create a household budget spreadsheet to:
- Use at least three advanced functions.
- Generate two different types of charts.
- Apply conditional formatting to highlight spending categories exceeding a set budget.

**Reflection:**
Post-lesson, consider student feedback, and review completed assignments to identify any areas needing re-teaching or additional practice in subsequent lessons.
