Exploring Fractions

Overview

This 45-minute lesson introduces Year 5 students to the concept of fractions, focusing on understanding, representing, and naming fractions such as halves, thirds, quarters, fifths, and eighths. The lesson aligns with the New Zealand Curriculum Refresh (nz_nzc_refresh) rational number objectives for Year 5, integrating key competencies including thinking, relating to others, participating, and using language, symbols and texts. It uses a SMOKE approach tailored for Australian year 5 students but grounded in the NZC framework with specificity.

Learning Objectives

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

• Identify, read, write (using symbols and words), and represent halves, thirds, quarters, fifths, and eighths as fractions of sets and regions using equal parts of a whole.
• Use fraction walls, bar models, and number lines to represent fractions visually and concretely.
• Understand and explain the numerator and denominator in fractional notation.
• Compare and order simple fractions (halves, thirds, quarters, fifths, and eighths).
• Begin to relate fractions to their equivalent decimal forms informally (introduction only).

Aligned to NZC Phase 2 Mathematics: Rational Numbers Year 5 outcomes and teaching considerations .

Resources Needed

• Fraction walls (paper strips or digital interactive tools).
• Paper strips or rectangles for folding and colouring fractions.
• Whiteboards and markers.
• Sets of counters or discrete objects (e.g., coloured beads).
• Printed number lines from 0 to 1.
• Worksheets for recording and exercises.
• Chart displaying fraction vocabulary and notation.
• Smartboard or projector for demonstrations.

Lesson Breakdown

1. Introduction & Engagement (10 minutes)

Activity:

• Display shapes divided into equal parts (e.g., circles, rectangles divided into halves, thirds, quarters, fifths, eighths).
• Ask: "What do you notice about the parts? Are they all the same size?"
• Introduce fractions as parts of a whole, explaining numerator and denominator symbols.

Teacher Explanation:

• Use fraction walls to show fractions visually, highlighting numerator (top number) and denominator (bottom number).
• Discuss how denominator tells us into how many parts the whole is split and numerator tells how many parts are considered.
• Link to everyday contexts: "If we share a pizza equally among friends..."

Pedagogical focus: concrete to pictorial representation with language support for ESL learners and to engage multiple learning styles .

2. Guided Exploration (15 minutes)

Activity:

• Each student folds paper strips to create halves, thirds, quarters, fifths, and eighths.
• Label and colour the parts; write fractions both in words and symbols.
• Use counters or beads: "If half of this group is red, how many red counters are there?"
• Place fraction strips on number lines—students mark fractions on individual number lines.

Teacher Role:

• Facilitate group discussion about comparing sizes of different fractions.
• Use 'think alouds' to articulate reasoning, e.g., "Which is bigger, 1/4 or 1/3? Why?"
• Reinforce correct fraction vocabulary (numerator, denominator, equal parts).

Establishes foundational understanding as per NZC emphasis on varied representations and explicit naming of fractions .

3. Collaborative Problem Solving (10 minutes)

Activity:

• In pairs, students use fraction walls or digital apps to compare pairs of fractions (e.g., 1/2 vs 2/4, 1/5 vs 3/15).
• Use prompts: Which fraction is bigger? Are these fractions equivalent?
• Introduce simple equivalent fractions informally using fraction walls, showing how 1/2 is the same as 2/4.

Teacher Facilitation:

• Encourage students to explain their reasoning to their partner.
• Circulate to provide support, ask probing questions, and correct misconceptions.

Supports NZC key competency "relating to others" and "thinking" .

4. Independent Practice and Reflection (8 minutes)

Activity:

• Students complete a worksheet where they colour parts of shapes, match fractional notation to images, and place simple fractions on number lines.
• Include tasks: writing fractions in words and symbols; comparing two fractions by size; identifying numerator/denominator.

Reflection:

• Conclude with a short oral reflection prompt: "What is a fraction? How do we know which fraction is larger?"
• Collect worksheets for assessment.

Assessment aligns with NZC expectations of students being able to read, write, and represent simple fractions successfully .

---

5. Plenary and Home Link (2 minutes)

• Quick quiz using whiteboards: teacher calls out fractions; students write or show with fingers (e.g., “Show me one half, one quarter…”).
• Suggest a simple home activity: identifying fractions in daily life (e.g., slices of fruit, parts of a chocolate bar).

---

Assessment and Feedback

• Formative assessment through observation of participation in discussions and paired work.
• Check student work on fraction representation and comparison for accuracy.
• Use questions to diagnose understanding of key terms numerator and denominator and equivalence ideas.
• Provide instant verbal feedback during activities and written feedback on worksheets.

---

Differentiation

• Support: Provide fraction walls and number lines with clear visuals; additional one-on-one assistance for struggling learners. Use concrete manipulatives extensively.
• Extension: Challenge advanced students to find equivalent fractions using multiplication of numerator and denominator, or to explain fractions in real-world context problems.
