### Lesson Outline
#### Introduction (10 minutes)
1. **Greeting and Warm-Up** (5 minutes)
- Begin with a brief greeting and review the previous lesson on basic arithmetic.
- Quick mental maths warm-up: Ask students simple questions involving addition, subtraction and multiplication.
2. **Introduction to Number Systems** (5 minutes)
- Explain the importance of understanding different number systems in everyday life.
- Provide real-life examples where fractions, decimals, and percentages are used (e.g., shopping discounts, recipes, statistics).
#### Main Activity (40 minutes)
1. **Explaining Conversions** (15 minutes)
- **Fractions to Decimals**:
- Explain that to convert a fraction to a decimal, you divide the numerator by the denominator.
- Use examples on the board (e.g., 1/2 = 0.5, 3/4 = 0.75).
- **Decimals to Percentages**:
- Explain that to convert a decimal to a percentage, you multiply by 100.
- Use examples on the board (e.g., 0.5 = 50%, 0.75 = 75%).
- **Percentages to Fractions**:
- Explain that to convert a percentage to a fraction, you place the percentage over 100 and simplify, if possible.
- Use examples on the board (e.g., 50% = 50/100 = 1/2, 75% = 75/100 = 3/4).
2. **Group Exercise** (10 minutes)
- Divide the class into small groups.
- Distribute the conversion chart handout and worksheets.
- Each group should complete a series of conversion exercises (provided on the worksheet).
3. **Class Discussion and Problem Solving** (15 minutes)
- Go through a few conversion problems on the whiteboard, ensuring all students understand the steps involved.
- Transition to word problems involving mixed operations with fractions, decimals, and percentages.
- Demonstrate one problem, then let students work on similar problems individually or in pairs.
- Discuss solutions as a class, encouraging students to share their methods and thought processes.
#### Conclusion (10 minutes)
1. **Recap and Summary** (5 minutes)
- Recap what has been learnt in the lesson.
- Ask students to summarise the key concepts of converting between fractions, decimals, and percentages.
- Reinforce the importance of these skills in daily life and future maths lessons.
2. **Homework Assignment** (5 minutes)
- Assign a worksheet with a mixture of conversion exercises and word problems for homework.
- Explain that they can refer to their conversion chart handouts for help.
- Encourage students to ask questions if any part of the lesson remains unclear.
**Assessment**:
- Monitor student participation during group work and class discussions.
- Review completed worksheets to assess individual understanding and identify areas needing reinforcement.
- Check homework for comprehension and accuracy.
**Extension Activity**:
- For advanced students, introduce complex word problems or explore the concept of recurring decimals and how they relate to fractions.
