### Procedure:
#### Introduction (10 minutes)
1. **Warm-Up Activity:**
- Begin with a brief review of fractions and decimals.

- Write the key vocabulary on the whiteboard: Percentage, Fraction, Decimal, Convert, Equivalent.
#### Direct Instruction (15 minutes)
1. **Explain Percentages:**
- Demonstrate with visual aids (pie charts, 100-grid) how percentages represent parts per hundred.
- Show how to convert percentages to fractions (e.g., 25% = 25/100 = 1/4) and decimals (e.g., 25% = 0.25).
2. **Guided Practice:**
- Work through several examples on the whiteboard with the class.
- Example: Convert 60% to a fraction and then to a decimal.
- Example: Find what percentage 30 is of 50.
#### Interactive Activity (20 minutes)
1. **Percentage Bingo:**
- Distribute Bingo cards with fractions, decimals, and percentages.
- Call out different percentage problems (e.g., "Find 50% of 60," "What is 0.75 as a percentage?").
- Students find and mark the correct answers on their Bingo cards.
- The first student to get a Bingo wins a small prize.
2. **Group Work:**
- Split students into small groups and distribute worksheet problems involving converting between fractions, decimals, and percentages.
- Circulate the room to provide support and monitor progress.
#### Independent Practice (10 minutes)
1. **Worksheet Activity:**
- Hand out individual worksheets with a variety of percentage problems.
- Encourage students to show their work and check their answers with a partner before submitting.
#### Conclusion (5 minutes)
1. **Review and Recap:**
- Summarize key points learned during the lesson.
- Ask a few students to share one new thing they learned about percentages.
2. **Quick Exit Ticket:**

### Assessment:
- Monitor students during guided practice and group work.
- Review Bingo cards and individual worksheets for understanding.
- Collect and review exit tickets to gauge student comprehension.
### Homework:
- Assign a worksheet with mixed problems on converting between fractions, decimals, and percentages.
- Provide a real-world context problem: "A store is offering a 20% discount. How much will you save on an item that costs $50?"
