- Explain the concept of a percentage as "parts per hundred."
- Discuss real-life examples of percentages (e.g., discounts, interest rates, statistics).
3. **Interactive Example**:
- Perform a simple calculation on the board, such as finding 20% of 50.
- Explain each step of the process clearly.
#### Direct Instruction (20 minutes):
1. **Converting Between Fractions, Decimals, and Percentages**:
- Demonstrate the process of converting fractions to percentages and vice versa.
- Show how to convert decimals to percentages by multiplying by 100.
2. **Calculation Techniques**:

- Use examples like finding 25% of 80, and go through the process step by step.
3. **Word Problem Solving**:
- Introduce percentage word problems.
- Model how to read the problem, set up the equation, and solve it.
#### Guided Practice (15 minutes):
1. **Worksheet Exercise**:
- Hand out a worksheet with a variety of problems.
- Include problems on converting fractions/decimals to percentages, basic percentage calculations, and word problems.
2. **Group Activity**:
- Divide students into groups of 3-4.
- Give each group a set of real-life situations (e.g., calculating sale prices, determining what percentage of a group has a certain characteristic).
- Have each group solve the problems and present their solutions to the class.
#### Independent Practice (10 minutes):
1. **Individual Worksheet**:
- Distribute a second worksheet with more challenging problems.
- Allow students to work independently to assess their understanding.
2. **Interactive Game**:
