National Curriculum Links
Mathematics: Fractions (Year 3)
- Compare and order unit fractions and fractions with the same denominator.
- Use >, <, = symbols to compare fractions.
Prior Knowledge Required
- Understanding of fractions as equal parts of a whole.
- Recognising and naming unit fractions and fractions with the same denominator.
Lesson Objectives
By the end of this lesson, the student will:
✅ Be able to compare fractions with the same denominator.
✅ Use greater than (>), less than (<), and equal to (=) symbols correctly.
✅ Represent and compare fractions using visual models and number lines.
Lesson Structure
1. Introduction (10 minutes) - Catch Their Curiosity!
🎭 Hook - "The Hungry Crocodile Game"
- Introduce the concept of comparing numbers using a fun story:
"Imagine a hungry crocodile that only wants to eat the biggest piece of food. The crocodile always opens its mouth towards the larger fraction!"
- Demonstrate with two paper cut-out crocodile mouths (one facing left, one facing right).
- Show simple examples (e.g. ½ and ¾) and have the student predict which way the crocodile will open.
- Write down the correct comparison using the greater-than (>), less-than (<), or equal (=) symbols.
📋 Key Terms to Introduce:
- Greater than (>)
- Less than (<)
- Equal to (=)
- Denominator (the number at the bottom of a fraction)
- Numerator (the number at the top of a fraction)
2. Guided Exploration (15 minutes) – Visual Models & Number Lines
📊 Activity 1: Fraction Bar Comparisons
- Provide fraction bars (paper strips divided into equal sections).
- Ask the student to compare ½, ⅓, and ¼ using the fraction bars.
- Question: "Which fraction takes up more space? Is ½ bigger than ¼? Can you explain why?"
- Encourage verbal reasoning and justification.
📏 Activity 2: Number Line Comparisons
- Draw a number line from 0 to 1 and mark common fractions (¼, ½, ¾, 1).
- Ask the student to place fractions such as 2/4, 3/4, and 1/4 on the number line.
- Reflection:
- "What do you notice about the order of the fractions?"
- "When do fractions become bigger or smaller on the number line?"
3. Independent Practice (20 minutes) – Hands-on Fun!
🎲 Game: "Fraction Pairs – Who’s Bigger?"
- Provide fraction cards (e.g., ⅔, ¾, ⅖, ⅗, etc.).
- Shuffle and place them face down.
- The student picks two cards, compares the fractions, and places the correct >, <, or = symbol between them.
- Extra Challenge: Use fractions with different denominators (support with visual models if needed).
✏ Mini-Quiz: "Which is Greater?" (Written Practice)
- ⅖ __ ⅘
- 3/6 __ ½
- ¼ __ ¾
- ⅔ __ ⅓
- 5/5 __ 1
4. Plenary (10 minutes) – Let's Reflect & Apply!
💭 Discussion Questions:
- "How can you tell which fraction is greater?"
- "How does a number line help us compare fractions?"
- "Can you make up your own fraction comparison problem for me to solve?"
🌟 Exit Challenge – "Reasoning Round"
- Give a real-world scenario (e.g., "A recipe needs ¾ cup of sugar, but you only have ½ cup. Do you have enough?").
- Encourage the student to explain their answer with reasoning rather than just giving a number.
Resources & Materials
✅ Fraction bars (printed or handmade paper strips)
✅ Number line printed on paper or drawn on a board
✅ Fraction comparison game cards
✅ Paper cut-out crocodile mouths (for the introduction)
✅ Whiteboard and markers or blank paper and pencil
Assessment & Differentiation
Assessment (How will progress be measured?)
✔ Verbal explanations during activities.
✔ Accuracy in fraction comparison game and mini-quiz.
✔ Application of learning in the exit challenge.
Differentiation (Adapting to the Student's Needs)
- Extra Support:
- Use physical fraction manipulatives for hands-on learning.
- Focus on unit fractions before extending to larger fractions.
- Greater Challenge:
- Compare fractions with different denominators using equivalent fractions.
- Introduce improper fractions and mixed numbers.
Teacher Reflection
✅ What worked well in the lesson?
✅ Did the student grasp key concepts easily, or did they require more support?
✅ What should be reinforced in the next lesson?
