🎯 Australian Curriculum Links

Learning Area: Mathematics
Strand: Number and Algebra
Sub-strand: Fractions and Decimals

Relevant Content Descriptions:

• Year 3 (ACMNA058): Model and represent unit fractions including 1/2, 1/4, 1/3, 1/5 and their multiples to a complete whole.
• Year 4 (ACMNA077): Investigate equivalent fractions used in contexts.

Proficiency Strands Emphasised:

• Understanding – Developing a deep understanding of unit fractions using visual representations.
• Fluency – Recognising and naming fractions accurately.
• Reasoning – Justifying how parts make a whole through discussion and comparison.

---

🚀 Learning Intentions

By the end of the lesson, students will:

• Understand unit fractions (fractions with a numerator of 1) as equal parts of a whole.
• Use pie charts and fraction bars to represent and compare unit fractions (e.g., ½, ⅓, ¼, ⅕, ⅙, ⅛).
• Explain how different unit fractions relate to one another and to the whole.

---

👍 Success Criteria

Students will be successful when they can:

• Accurately represent unit fractions using manipulatives or drawings.
• Label and describe fractions as parts of a whole.
• Explain why, for example, 1/4 is larger than 1/6 using visual representations.

🛠️ Materials Needed

• Large fraction circles (laminated or printed on card)
• Fraction bars
• Mini whiteboards and markers
• "Fraction Detective" task cards (provided below)
• A3 paper for group work
• Pencils, glue, scissors
• Digital timer or stopwatch
• Sticky notes (two colours)
• Mini chalkboards for spontaneous assessment

⏰ Time Breakdown

1. Welcome & Warm-Up | 5 minutes

Activity: “Fraction Freeze”

• Play music and have students move around the room.
• When the music stops, flash a fraction card (e.g., 1/2, 1/4, 1/8).
• Students must freeze in a pose that reminds them of that fraction (e.g., holding out one hand if they think of 1/2).
• Quick call-outs: “Why did you pose that way?” (Builds fraction intuition and connection to physical representation.)

---

2. Tuning In | 5 minutes

Think-Pair-Share: “What is a unit fraction?”

• Write “unit fraction” on the board. Invite students to jot down ideas individually (1 min).
• Pair up and discuss thoughts (2 mins) before sharing as class (2 mins).
• Teacher records ideas on anchor chart, noting correct definitions and misconceptions for future reference.

---

3. Explicit Teaching | 10 minutes

Visual Modelling with Teacher-Led Exploration

• Use a large magnetic whiteboard pie chart.
• Demonstrate 1 whole divided into halves, thirds, quarters, fifths.
• Emphasise: Unit fractions all have 1 in the numerator – one equal part of something.
• Show multiple ways to divide the same circle and label each piece (e.g., two halves labelled 1/2, three thirds labelled 1/3).
• Ask: “Which piece is bigger – 1/3 or 1/4? Why?”

Strategy Highlight: Flip the question. “If I want a bigger slice of pizza, should I take 1/3 or 1/5?”

4. Hands-on Learning | 20 minutes

Activity Rotation: Fraction Stations

Group students in groups of 5 (4 groups total) and rotate every 5 minutes.

Station 1: Fraction Pizza Party

• Students create fraction circle pizzas using pre-cut slices.
• Task: Build a pizza using one type of fraction – then write the name (e.g., "My pizza is made of eighths").
• Challenge: Build the same whole with different fractions (e.g., two 1/2 slices = one whole).

Station 2: Fraction Bars Match-Up

• Match fraction bars with the correct unit fraction cards.
• Task: Sort bars under headings on a poster: ‘larger pieces’ vs ‘smaller pieces’.

Station 3: Fraction Detectives 🕵️

• “Fraction Clue” cards describing a mystery fraction.
• Students use clues to identify the correct unit fraction (e.g., “I am a part of a whole. There are 6 equal parts. I represent one of them.” → 1/6).
• Bonus: Write your own fraction riddle for your classmates.

Station 4: Draw & Compare

• Students draw different unit fractions on mini whiteboards or A3 paper.
• Task: Draw a shape and divide it into different fractions – label it clearly.

---

5. Reflection & Exit Slip | 7 minutes

Discussion Prompt:

• “Explain to a Prep student what a unit fraction is.”
• How did visualisation help you understand fractions better?

Student Task:

• Draw one fraction shape and label it with a unit fraction on a sticky note.
• Place sticky note on class “Fraction Gallery” wall under the correct heading: 1/2, 1/3, 1/4, etc.

Teacher Observation:

• Walk around, take anecdotal notes, and photograph sticky notes for reflection/bookwork evidence.

---

6. Optional Extension (Fast Finishers | Homework)

“Fraction Around Me” Scavenger Hunt:

• Find 3 objects at home or on the way to school that could be divided into equal parts (e.g., pizza, sandwich, chocolate bar).
• Sketch them and show how they could be split into halves, thirds, quarters.

---

🧩 Differentiation

Support:

• Provide pre-labelled models and work with teacher aide or in guided group.
• Use shapes students are familiar with (e.g. circles, rectangles) for visual connection.

Extension:

• Explore non-unit fractions (e.g., 2/4, 3/6) using extra slices.
• Challenge them with the concept of equivalent unit fractions visually.

---

📘 Assessment Opportunities

• Observations during warm-up and station rotations.
• Responses in class discussion.
• Sticky note exit slips.
• Student-created riddles clarify understanding.
• Use learning progressions in the curriculum to determine next steps.

🙌 Teacher Reflection Prompt (Post-Lesson)

• Were students able to clearly describe unit fractions?
• Which visual model appeared most accessible or effective for conceptual understanding?
• What misconceptions appeared during the stations and how might these guide Lesson 3?
