Lesson Plan

Introduction (10 minutes)

Activity:

1. Engagement Question: Ask the class, "If I eat one out of four slices of a pizza, what fraction of the pizza did I eat?"
2. Explanation: Use visual aids to introduce fractions and decimals. Show how a pie or a pizza can be divided into equal parts.
3. Link to Prior Knowledge: Recap any previous lessons on numbers and division to connect students' existing knowledge with new concepts.

Development (20 minutes)

Group Activities:

1. Fraction Match-Up: Use fraction flashcards. Students match visual representations to written fractions (1/2, 1/4, 3/4, etc.).
2. Decimal Introduction: Introduce decimals by relating them to fractions (e.g., 1/2 is the same as 0.5) using visual aids and the interactive whiteboard.
3. Compare and Order: Hand out worksheets where students need to arrange fractions and their corresponding decimal forms in ascending or descending order.

Application and Practice (10 minutes)

Individual Work:

• Students complete a worksheet where they convert fractions to decimals and vice versa.
• Include real-life application questions, such as finding fractions and decimals in shopping receipts or in measuring lengths using rulers.

Conclusion (5 minutes)

Recap and Reflect:

• Quick recap of the day’s lesson. Ask students to volunteer to explain what they learnt about fractions and decimals.
• Discuss how understanding these concepts can help in everyday life, like cooking or shopping.

Assessment

• Observe student participation and understanding during group activities.
• Review worksheets to assess individual understanding and provide feedback.

Follow-Up

• Assign students to find examples of fractions and decimals in their home environment and report back in the next class.
• Suggest parents/guardians to practice fractions and decimals during shopping or cooking activities.
