Fraction Mastery Challenge

Lesson Overview

• Year Group: Year 3
• Subject: Mathematics
• Unit: Fraction Fun Adventures (Lesson 7 of 9)
• Lesson Duration: 60 minutes
• Curriculum Reference: National Curriculum for England – Year 3 Mathematics, Fractions:
  • Add and subtract fractions with the same denominator within one whole (e.g. 5/7 + 1/7 = 6/7).
  • Solve problems that involve fractions using practical resources and visual models.

Learning Objectives

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

1. Accurately add and subtract fractions with the same denominator within one whole.
2. Apply their understanding to solve mixed operation problems involving fractions.
3. Explain their reasoning using fraction models and real-life contexts.

Resources Needed

• Fraction strips or fraction circles
• Mini whiteboard and pens
• Printable challenge cards with fraction problems
• Small counters or cubes for hands-on practice
• Pre-prepared “Fraction Adventure” game board
• Reflection worksheet

Lesson Structure

1. Starter Activity – Fraction Riddle (10 minutes)

Objective: To warm up the student’s fraction thinking skills.

• Begin with the following riddle:
  "I am a fraction. My numerator is 3, and my denominator is 5. What am I?"
• Ask the student to write their answer on their mini whiteboard.
• Discuss how they identified the correct fraction and reinforce the importance of numerators and denominators.

2. Revisiting Prior Learning (10 minutes)

Objective: To consolidate understanding of adding and subtracting fractions before applying it to mixed operations.

• Use fraction strips or circles to model:
  • Adding fractions: "If I have 2/6 of a pizza and eat another 3/6, how much have I eaten in total?"
  • Subtracting fractions: "If I had a full chocolate bar (6/6) but ate 4/6, how much is left?"
• Check for understanding by having the student demonstrate an example using the manipulatives.

3. Main Activity – Fraction Adventure Challenge (25 minutes)

Objective: To practise adding and subtracting fractions through an engaging game-based approach.

How the Game Works:

• Introduce the “Fraction Adventure” board, which contains fraction problems along a winding path.
• The student rolls a die and moves along the path, stopping to solve the fraction problem they land on.
• Correct answers allow them to collect a “star token.” Five tokens complete their adventure.
• Questions vary between:
  • Simple addition (e.g. 2/8 + 3/8)
  • Simple subtraction (e.g. 5/9 - 3/9)
  • Mixed word problems (e.g. "Lucy had 4/5 of a cake but gave 1/5 to a friend. How much does she have left?")
• Encourage the student to verbalise their reasoning as they solve each problem, using fraction models if necessary.

Challenge Extension:

• If the student completes the game early, introduce a “mystery fraction puzzle,” where they must determine a missing fraction in an equation (e.g. _/7 + 2/7 = 5/7).

4. Reflection and Mini-Assessment (10 minutes)

Objective: To consolidate learning and check for understanding.

• Provide the student with a reflection worksheet containing the prompts:
  • “One thing I was confident about today…”
  • “One thing I found tricky…”
  • “One thing I want to practise more…”
• Ask them to solve a final challenge independently on their mini whiteboard:
  “Ben had 7/12 of a pizza. He gave away 4/12. How much does he have now?”
• Review the answer together and address any misconceptions.

Assessment and Next Steps

• Formative Assessment:

  • Observe responses during the fraction game – Is the student using the correct steps?
  • Check the reflection worksheet for self-awareness of strengths and areas for development.
  • Evaluate their final independent problem for accuracy.

• Next Lesson (Lesson 8 of 9):

  • Moving towards real-life fractions – solving practical fraction problems in everyday contexts.

Teacher’s Notes & Adaptations

• For learners who need support: Use fraction visuals for every question and reinforce “same denominator” rules step by step.
• For learners who need challenge: Introduce missing fraction puzzles and word problems with reasoning elements.
• Engagement Tip: Frame the lesson as a “Fraction Explorer Mission” where they must collect answers to complete their journey.
