Fractions Unveiled

Overview

This 45-minute lesson introduces Year 5 students in New Zealand to the concept of fractions using simple, practical examples. The lesson aligns closely with the New Zealand Curriculum Refresh, focusing on the Number and Algebra strand, particularly the rational numbers strand that includes identifying, reading, writing, and representing fractions (halves, thirds, quarters, fifths, sixths, eighths) and positioning them on number lines. It also supports the development of the key competencies of Thinking and Using Language, Symbols, and Text in mathematics.

Curriculum Alignment

Learning Area: Mathematics & Statistics

Strand: Number and Algebra
Strand Sub-element: Number & Algebra (Rational numbers)
Focus:

• Identify, read, write and represent fractions (halves, thirds, quarters, fifths, sixths, eighths) of sets and regions using equal parts of the whole and by positioning on a number line.
• Understand the numerator as how many parts are taken and the denominator as total equal parts the whole is divided into.
• Use mathematical language associated with fractions (e.g., numerator, denominator, equal parts).
• Develop fluency with fractions through practical activities involving paper folding, fraction walls, and number lines.
• Compare and order common fractions, identifying equivalence where applicable.

Learning Objectives

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

• Define a fraction as part of a whole split into equal parts.
• Identify numerator and denominator in fraction notation.
• Represent halves, quarters, and eighths using visual aids and paper folding.
• Place simple fractions on a number line.
• Use correct fraction language when explaining their work.

Lesson Breakdown

Time	Activity	Description and Resources
0-5 mins	Introduction to Fractions	Teacher introduces fractions using a real-life example (e.g., slicing a pizza or chocolate bar). Explain: numerator = parts taken; denominator = total parts. Use visual aids (paper shapes, pizza slice).
5-15 mins	Hands-on Paper Folding Activity	Children fold coloured paper strips to create halves, quarters and eighths. Label parts with fraction symbols and words (e.g., 1/2, one-half). Discuss how the paper was split and parts named.
15-25 mins	Fraction Wall Exploration	Use fraction walls or create one on the board with paper strips to compare halves, quarters, eighths visually. Discuss equivalence and which fractions are bigger or smaller.
25-35 mins	Number Line Placement Activity	Students place fraction cards (1/2, 1/4, 3/4, 1/8 etc.) on a pre-drawn number line. Discuss ordering fractions and relate this to the fraction wall. Emphasise fraction as a number on the number line.
35-40 mins	Group Discussion and Mathematical Language	Prompt students to articulate their understanding using terms like numerator, denominator, equal parts, whole, fractions as numbers, and comparison language (e.g., bigger, smaller, equal).
40-45 mins	Exit Reflection and Quick Assessment	Students respond on mini whiteboards: Write or draw one fraction and explain what numerator and denominator mean. Teacher collects these for formative assessment.

Teaching and Learning Considerations

• Use concrete materials and real objects to make fractions relatable and tangible.
• Support students to verbalise their reasoning to reinforce understanding and language.
• Provide visual scaffolds including fraction walls and number lines as references during activities.
• Check for understanding frequently, providing examples and non-examples.
• Encourage peer discussion to deepen mathematical thinking and collaboration.
• Use questioning prompts such as:
  • "What does the denominator tell us?"
  • "If I take 3 out of 4 parts, which fraction do I have?"
  • "Can two different fractions be equal? How do you know?"

Assessment for Learning

• Observations during activities to gauge participation and understanding.
• Mini whiteboard exit task: Can the student correctly write and verbalise what the numerator and denominator represent?
• Use student explanations during group work as formative data to plan next teaching steps around fraction equivalence and addition in subsequent lessons.

---

Resources Needed

• Coloured paper strips for folding
• Fraction walls (physical or drawn)
• Pre-drawn fraction number lines on boards or large paper
• Mini whiteboards and markers for each student
• Real-life fraction examples (e.g., toy pizza, chocolate bars, fruit cut into pieces)

---

Extension Ideas (for faster learners or follow-on lessons)

• Investigate equivalent fractions using fraction walls and number lines.
• Simple addition of fractions with same denominators using fraction strips (e.g., 1/4 + 2/4).
• Introduce improper fractions and mixed numbers for more advanced students.

This lesson plan "Fractions Unveiled" is designed to actively engage Year 5 students with foundational fraction concepts through tactile, visual, and collaborative strategies, all firmly grounded in the New Zealand Curriculum Refresh's learning objectives and best practices in mathematics education.
