Introducing Simple Fractions

Overview

This 45-minute lesson introduces Year 5 students (age 9-10) to the concept of fractions using simple and engaging examples. It aligns specifically with the New Zealand Curriculum Refresh (Te Mātaiaho) learning objectives for Year 5 within the Number and Algebra strand, focusing on rational numbers and developing students’ understanding of fractions as numbers that represent parts of a whole.

Learning Objectives

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

• Identify and describe fractions as parts of a whole using the terms numerator and denominator.
• Represent simple fractions (halves, quarters, thirds) using practical materials and drawings.
• Read and write fractions using words and symbols.
• Understand that fractions are numbers that can be located on a number line.
• Compare simple fractions using visual aids.
• Develop confidence in fraction vocabulary and notation.

Curriculum References

• Number and Algebra – Rational Numbers, Years 5 & 6:
  Identify, read, write, and represent halves, thirds, quarters, fifths, sixths, and eighths as fractions of sets and regions, using equal parts of the whole and by positioning on the number line.
• Mathematics & Statistics Key Competencies:
  Thinking, Using language, symbols, and texts
• Supports the curriculum focus on using materials and diagrams to solve problems involving fractions.

Lesson Timeline & Activities

1. Engagement & Introduction (5 minutes)

• Begin with a question: "Have you ever shared a chocolate bar or a pizza equally with your friends? How did you divide it?"
• Introduce vocabulary: numerator (top number – how many parts we have), denominator (bottom number – how many parts the whole is divided into).
• Show a whole object (like a circle or rectangle paper) and explain "This is one whole."

2. Exploration with Materials (15 minutes)

• Hands-on activity: Fraction strips or paper folding
  Each student receives a strip of paper.
  • Fold the paper strip into 2 equal parts: label one part as 1/2.
  • Fold into 4 equal parts: label one part as 1/4.
  • Label the numerator and denominator on the strip.
• Use fraction walls or fraction circles to visually compare 1/2, 1/4, and 1/3 (if available).
• Encourage students to discuss what they notice about equal sharing and that the denominator tells how many equal parts there are.

3. Representation & Language Development (10 minutes)

• Drawing Fractions & Number Lines
  • Draw simple shapes (rectangles/circles) on the board divided into equal parts. Invite students to label fractions.
  • Demonstrate placing fractions on a number line between 0 and 1. Show that 1/2 is exactly halfway.
• Model reading fractions aloud and writing them with numerator over denominator (e.g., one half = 1/2).

4. Interactive Group Activity: Fraction Sharing Game (10 minutes)

• Pose a sharing problem with familiar items (e.g., "If you have 8 apples and want to share them equally among 4 people, how many apples does each person get?" – introducing 1/4 parts).
• Use counters or blocks for hands-on equal sharing in groups of 4 or 3.
• Have students express the result as fractions and explain in their own words.

5. Reflection & Formative Assessment (5 minutes)

• Quick quiz-style oral questions:
  • "What fraction of the strip is shaded if one part out of four is coloured?"
  • "Which is bigger, 1/2 or 1/4?"
  • "Write the fraction for this shape." (pointing to visual examples)
• Use thumbs up/down and short answers to assess understanding.
• Encourage students to explain their thinking briefly to a partner or the class.

Resources & Materials

• Paper strips for folding
• Fraction walls or fraction circles (physical or digital)
• Counters or small objects for sharing task
• Whiteboard and markers for drawing shapes and number lines
• Visual fraction charts

Teaching Considerations

• Use concrete materials first before moving to symbols to ground students' understanding in physical experience.
• Scaffold language carefully – consistently use terms "numerator" and "denominator" with students.
• Allow for hands-on interaction and small group discussion to foster collaboration and peer learning.
• Anticipate different paces: prepare extension questions for early finishers (e.g., finding 3/4) and supportive prompts for those needing more help.
• Emphasise the link between fractions and division/share concepts familiar to students.

---

Extension & Enrichment Ideas

• Introduce fractions as division (e.g., 1/2 as 1 ÷ 2) using simple calculations.
• Explore equivalent fractions using fraction strips (e.g., show 2/4 equals 1/2).
• Digital tools: use interactive apps or simulations for fraction walls and number line placements for self-paced practice.

Summary

This lesson immerses Year 5 students in the foundational understanding of fractions through concrete experiences, visual representations, and language development fully aligned to the refreshed New Zealand Curriculum expectations. It balances understanding, vocabulary, and practical application with clear assessment opportunities within 45 minutes for approximately 20 students.
