Fractions Overview

Overview

Year Group: 11
Duration: 45 minutes
Class Size: 6 students
Unit: Mastering Maths Concepts (Lesson 1 of 20)
Topic: Fractions Overview
National Curriculum Reference:

• Number – fractions (KS3 content consolidated, appropriate revision for Year 11)
• NC Maths Programme of Study – Number: Fractions, decimals and percentages
• Key Objectives:
  • Recognise and use fractions as numbers: unit fractions and non-unit fractions with small denominators
  • Recall and use equivalences between simple fractions, decimals and percentages, including in different contexts (KS3, consolidated for Year 11)

Learning Objectives

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

• Understand and articulate what a fraction is, including the roles of numerator and denominator.
• Identify and distinguish between proper fractions and whole numbers expressed as fractions.
• Create simple fractions from whole numbers and visual representations.
• Use correct mathematical vocabulary related to fractions confidently.

Keywords

• Numerator
• Denominator
• Proper fraction

Resources Needed

• Whiteboard and markers
• Fraction circles or fraction bar manipulatives
• Visual aids (pre-prepared posters or slide with fraction diagrams)
• Printed quick quiz (5 questions)
• Mini whiteboards and pens for all students

Lesson Structure

1. Do Now (5 minutes) – Quick Fraction Review

• As students enter, on the board display 5 quick fraction questions such as:
  • What fraction of this shape is shaded? (show a simple image of a circle divided into 4 parts, 1 shaded)
  • Write the fraction for one half, one quarter, and three quarters.
• Students will write answers on mini whiteboards.
• Quick class feedback to check prior knowledge and activate prior learning.

2. Introduction and Input (10 minutes) – Introducing Fractions with Visual Aids

• Define a fraction as "a number that represents part of a whole."
• Explain numerator (top number) and denominator (bottom number) with clear examples on the board.
• Show visual aids: fraction circles and bars showing different fractions (e.g., 1/2, 3/4, 2/3).
• Differentiate proper fractions (numerator less than denominator) from improper fractions (brief mention; main focus on proper fractions here).
• Engage students by asking them to come up and shade parts on fraction circles to demonstrate the fraction.

3. Main Task (20 minutes) – Identify and Create Simple Fractions

• Activity 1: Given diagrams of shapes divided into parts, students identify the fraction shaded (3 minutes).
• Activity 2: Students work in pairs to use fraction bars to create specified fractions from whole numbers (e.g., Make 3/5 of a bar, or write a fraction that shows 7 parts out of 10). They write the corresponding fractions on mini whiteboards and explain to the class. (10 minutes)
• Activity 3: Challenge task for able students—write whole numbers as fractions with denominator 1 (e.g., 5 = 5/1) and explain what numerator and denominator represent in this context. (7 minutes)

4. Plenary (10 minutes) – Quick Quiz and Discussion

• Distribute a printed quick quiz with 5 questions:
  1. Identify the numerator and denominator in the fraction 4/7.
  2. Is 5/3 a proper fraction? Why or why not?
  3. Write a fraction to represent three parts from a total of eight.
  4. Convert the whole number 6 into a fraction.
  5. What fraction is shown if 2 parts are shaded out of 5?
• Collect responses, review answers as a class, clarifying any misconceptions.
• Praise participation and reinforce keywords.

Assessment

• Formative: Use mini whiteboards during "Do Now" and main task to monitor understanding in real-time.
• Summative: Quick quiz at plenary to assess individual understanding of key concepts and vocabulary.
• Verbal questioning throughout to check for conceptual clarity.

---

Differentiation

• Support: Provide fraction diagrams with fewer parts, and number lines to support visual learners.
• Challenge: Encourage higher-attaining students to represent improper fractions and conversion between mixed numbers and improper fractions (preparing for upcoming lessons).
• All students to explain reasoning in pairs to deepen understanding.

---

Homework Suggestion

• Create a fraction poster showing five different fractions with visual representations and explanations of numerator and denominator to reinforce today's learning.

---

Teacher Notes / Tips

• Use enthusiastic and clear explanations to demystify fractions for the students.
• Incorporate tactile learning through manipulatives to aid retention.
• Emphasise correct terminology – getting these terms right early sets a strong foundation.
• Aim to create a supportive environment for the small class where every student contributes.

National Curriculum Links Summary

This lesson addresses the KS3 National Curriculum for England Number topics on fractions, consolidated for Year 11 to ensure fluency and understanding of core fractional concepts essential for higher GCSE work in number and ratio. It reinforces students’ conceptual understanding through visual aids and practical tasks, aligning with the programme of study:

• Recognise and use fractions as numbers
• Understand the meaning of numerator and denominator
• Identify and write proper fractions
• Develop fluency in fraction notation leading to application in later units (e.g., ratio, proportion, algebra).
