Lesson Structure

1. Starter Activity (5 minutes) – Fraction Warm-up

• Objective: Activate prior knowledge and ensure students are confident in identifying fractions.
• Activity:
  • Display different fractions on the board (e.g. 2/8, 4/8, 6/8).
  • Ask students to represent these fractions using their fingers (e.g. for 4/8, they hold up four fingers on one hand while showing a total of 8 fingers).
  • Quick class discussion: "What do you notice about these fractions?" (i.e., denominators are the same)
  • Introduce today’s topic: Adding and Comparing Fractions with the Same Denominator

2. Teaching Input (10 minutes) – Fractions Explained

Step 1: Adding Fractions with the Same Denominator

• Explain: If the denominator (bottom number) is the same, you only add the numerators (top numbers). Example:

  3/7 + 2/7 = (3+2)/7 = 5/7

• Visual Representation: Draw fraction bars on the board to show how adding works.

Step 2: Comparing Fractions with the Same Denominator

• Explain: When fractions have the same denominator, the larger numerator means the larger fraction. Example:
  • 5/8 is greater than 3/8 because 5 is larger than 3.
• Use a number line: Draw a fraction number line to show fraction placement and relative sizes.

3. Main Activity (10 minutes) – Fractions Treasure Hunt!

Objective:

To apply their knowledge of adding and comparing fractions in a fun, hands-on way.

Setup:

• Each table becomes a ‘fraction island’.
• Each group receives 6 fraction cards with fractions that have the same denominator (e.g. 1/6, 3/6, 4/6).
• A ‘Number Pirate’ (teacher or student) calls out a fraction challenge such as:
  • “Find two cards that add up to 5/6”
  • “Who has the biggest fraction on your island?”
  • “Who has the smallest fraction?”
• Groups work together to solve the challenges and hold up their answers.
• Bonus challenge: Arrange all your fraction cards from smallest to largest on your island!

Engagement Factor:

• The ‘Number Pirate’ (teacher) rewards accurate answers with a ‘Golden Fraction Coin’ (stickers or points). The island with the most coins wins the treasure!

4. Plenary (5 minutes) – Fraction Reflection

• Recap learning: Ask the class:
  • “What happens when we add fractions with the same denominator?”
  • “How do we know which fraction is larger?”
• Quickfire Questions:
  • “What is 2/9 + 4/9?”
  • “Which is greater: 6/10 or 3/10?”
• Exit Ticket:
  • Each pupil writes an example of a fraction sum and compares two fractions before leaving the lesson.

---

Assessment Opportunities

• Observation: Watch students as they complete the group challenge.
• Class discussions: Listen for correct reasoning and explanations.
• Exit ticket responses: Check for understanding of adding and comparing fractions.

---

Resources Needed

• Fraction cards with numerators from 1-6 and denominators of 6, 8, or 10.
• Fraction number line drawn on the board.
• ‘Golden Fraction Coins’ (stickers or points).

---

Differentiation

• For struggling students: Use fraction bars to give a visual representation of fraction addition.
• For high-achieving students: Introduce missing fraction sums (e.g., “What number must be added to 3/6 to make 5/6?”).

Teacher Reflection After Lesson

• Were students engaged in the interactive activity?
• Did they successfully add and compare fractions?
• What misconceptions needed correcting?
