Mastering Fractions Together
Curriculum Area: Mathematics
Year Group: Year 4
GB Curriculum Level: Lower Key Stage 2
Main Objective: Recognise, compare, and work with fractions (e.g., halves, thirds, and quarters) and understand how fractions relate to division and shapes. Specifically aligned to the GB National Curriculum requirement for Year 4: "Recognise and show, using diagrams, families of common equivalent fractions."
Learning Outcomes
By the end of the lesson, students will be able to:
- Identify and name common fractions (e.g., halves, thirds, quarters).
- Recognise equivalent fractions using visual aids and number representations (e.g., 1/2 = 2/4).
- Use practical activities to split a shape or quantity into equal parts and describe fractions.
- Solve simple problems involving fractions in a real-world context.
Lesson Breakdown (45 Minutes)
1. Starter Activity – Fraction Detective (10 minutes)
- Objective: Activate prior knowledge of fractions in an engaging way.
- Materials: Pre-prepared mystery envelopes (5 envelopes with laminated pictures or cards of part-whole fractions, such as shapes split into parts, pizza slices, etc.).
Activity Flow:
- Split the class into groups of 6. Each group becomes a "Fraction Detective Team."
- Each envelope contains clues (like pictures of fractional shapes or "mystery fractions"). The group must collaboratively figure out the fraction being described (e.g., a picture of a pizza cut into 4 parts, with 1 part shaded = 1/4).
- Groups briefly share their "discovery" with the class, reinforcing fractional vocabulary.
Teacher's Role: Circulate to ensure proper use of fraction language (e.g., numerator, denominator) and encourage teamwork.
2. Input/Teaching Time – Equivalence Magic (15 minutes)
- Objective: Teach students how to recognise and create equivalent fractions.
- Materials: Interactive whiteboard, fraction bars (physical or virtual), and printed "fraction walls."
Teacher Explanation:
- Begin by showing a fraction wall on the interactive whiteboard. Highlight and explain that fractions can represent the same value in different forms (e.g., 1/2 is the same as 2/4, 3/6).
- Use fraction bars to demonstrate how equivalent fractions "fit" into the same length (e.g., stack the bars for 1/2 and 2/4).
- Ask guiding questions: "How many quarters make one half?" "Why do you think 1/2 equals 2/4?"
Interactive Discussion:
- Pause for student input and clarification as needed.
- Use their ideas to reinforce the concept visually and verbally.
Quick Check (3 minutes):
- Write fractions on the board and challenge students to identify a matching equivalent fraction from the fraction wall (e.g., is 3/6 equal to 1/3 or 1/2?).
3. Hands-On Activity – Fraction Fair (15 minutes)
- Objective: Allow students to explore fractions physically and visually.
- Materials per group (6 groups): Circular fraction puzzles (sliced into halves, thirds, quarters, etc.), blank paper strips, rulers, coloured pencils.
Activity Flow:
- Create "Fraction Fairs" at each table.
- Students work in pairs to:
a. Complete the fraction puzzles to match wholes using equivalent pieces (e.g., "I need two quarters to make a half!").
b. Draw their own equivalent fractions using the paper strips (e.g., split a paper strip into halves and then into quarters – compare and describe equivalence).
- They record their fractional discoveries in their maths books and label fractional splits (e.g., "1/2 = 2/4").
Extension for Quick Finishers:
- Challenge them to create their own fraction problem for a peer to solve.
Teacher's Role: Rotate between groups offering support, checking accuracy, and prompting deeper thinking (e.g., "What happens if we split the same strip into 8 pieces instead?").
4. Plenary – Fraction Rap (5 minutes)
- Objective: Consolidate the day’s learning in a fun, memorable way.
- Materials: Prewritten "Fraction Rap" lyrics (adjust based on the class – provide printed copies or display on the board).
Lyrics Example:
"One half is like two quarters,
Fractions are like maths supporters!
Slice the pizza, make them fair,
Look for halves and thirds out there!"
- Lead the class in performing the fraction rap together. Encourage clapping or simple beats on desks to make it lively.
- Pause periodically to ask questions like, “What’s another equivalent fraction for a half?”
This serves as a fun and interactive conclusion while reinforcing the terminology and concepts.
Differentiation
Support:
- Students needing extra help will use pre-coloured fraction bars or diagrams to scaffold understanding without relying only on abstract numbers.
- Provide a buddy system with confident students assisting.
Challenge:
- More able students will create their own shapes and split them into non-standard fractions (e.g., 5ths, 6ths) to explore further fraction equivalences.
Assessment Opportunities
- Observation: During the detective game and hands-on activities – check if students can articulate fractional terms and recognise equivalences.
- Fraction Fair Work: Review written work from hands-on activity (e.g., drawings of equivalent fractions).
- Questioning: Target specific students with quick plenary questions to assess understanding verbally.
Resources Checklist

- Fraction wall (printed or virtual)
- Fraction bars
- Circular fraction puzzles
- Paper strips, rulers, and coloured pencils
- Fraction rap lyrics
Reflection for Teacher
- Did the students grasp the concept of equivalence?
- Were the activities pitched correctly for the class level?
- Which students need further intervention, and which could progress to more advanced fractional work?
This hands-on, visual, and musical approach makes fractions engaging and memorable for students, while closely aligning with GB Year 4 curriculum standards.
