Australian Curriculum Alignment

Content Descriptions:

• Year 1: Recognise and describe one-half as one of two equal parts of a whole (ACMNA016)
• Year 2: Recognise and interpret common uses of halves, quarters and eighths of shapes and collections (ACMNA033)
• Year 3: Model and represent unit fractions including 1/2, 1/4, 1/3, 1/5 and their multiples to a complete whole (ACMNA058)

Learning Objectives

By the end of the lesson, students will be able to:

1. Identify and describe fractions as part of a whole.
2. Create hands-on fraction models using everyday objects.
3. Recognise halves, quarters, and eighths in various contexts.
4. Understand that fractions represent equal parts of a whole.

Materials

• A large pizza (cut into 6 or 8 slices for demonstration)
• Paper plates
• Coloured markers or crayons
• Fraction strips (pre-cut paper strips to represent fractions)
• Small classroom whiteboards and markers
• Interactive whiteboard or projector (optional)
• Plastic knives for cutting fruit (e.g., apples or oranges)
• Fraction flashcards

Lesson Steps

Introduction (5 minutes)

1. Greeting and Setting the Context:

   • Greet the class enthusiastically: "Good morning, mathematicians! Today we are going to explore a fun part of maths – fractions!"

2. Whole Class Discussion:

   • Show the large pizza. Ask: "What do you think we are going to learn with this pizza?" Lead students to mention 'parts' or 'slices.'
   • Explain: "When we talk about parts of a whole, like slices of a pizza, we are talking about fractions."

Main Activity (20 minutes)

1. Pizza Fraction Demonstration (5 minutes):

   • Cut the large pizza into slices. Hold up one slice and explain: "This is one part of our pizza. If we cut the pizza into 4 parts (quarters), each part is called a fraction – in this case, one quarter."
   • Show various fractions using the pizza (half, quarters, and eighths).

2. Hands-On Activity - Paper Plate Pizzas (10 minutes):

   • Distribute paper plates and coloured markers to each student.
   • Instruct students to draw and colour a whole pizza on their plate.
   • Guide them on how to draw lines to divide their 'pizza' into halves, quarters, and eighths.
   • Walk around the room offering assistance and ask questions to check for understanding.

3. Classroom Fraction Exploration (5 minutes):

   • Break students into small groups (4-5 students per group).
   • Provide each group with fraction strips and fraction flashcards.
   • Challenge them to match the fraction flashcards to the correct fraction strips.
   • Allow students to explore, share, and discuss their findings.

Conclusion (5 minutes)

1. Discussion and Reflection:

   • Bring the class back together. Ask: "What did you learn about fractions today?"
   • Allow 2-3 students to share their newly learnt concepts.

2. Real-World Application:

   • Explain how fractions are used in everyday life, such as in cooking and sharing food.

3. Interactive Quiz:

   • Display various objects (like fruits cut into parts) and ask students to identify the fractions.
   • Encourage quick responses and celebrate correct answers.

Extension Activity (Optional)

• Fraction Art:
  • Provide art supplies and ask students to create fraction art using different shapes and colours, reinforcing the concept of fractions being equal parts of a whole.

Assessment

• Informal Observation:

  • During activities, observe and take notes on student participation and understanding.

• Quick Exit Quiz:

  • Before they leave, ask students to draw a fraction of their choice (either half, quarter, or eighth) on a small piece of paper and submit it.

Teacher Reflection

• Post-Lesson Review:
  • Reflect on student engagement and understanding.
  • Note which students may need more support with the concept and plan follow-up activities if necessary.

Resources

• Large demonstration pizza (real or cardboard)
• Coloured markers
• Pre-cut fraction strips
• Fraction flashcards

This lesson plan taps into hands-on learning and real-life experience to make the abstract concept of fractions concrete and accessible for young learners.
