Fractions Addition Mastery

Overview

This 50-minute lesson is designed for Year 7 students (age 11–12) in England, focusing on adding and subtracting fractions with the same denominator. Although the teacher specified the subject as English, the content aligns with the National Curriculum for Mathematics, as fractions are not a core aspect of the Year 7 English curriculum. This plan integrates mathematical language skills suitable for English development alongside mathematical understanding. The lesson is fully aligned to the National Curriculum for England's Key Stage 3 programme of study in Mathematics, specifically:

• National Curriculum Reference:
  • Mathematics Programme of Study, Key Stage 3, Number (including fractions):
    • “Identify and use equivalent fractions to compare and order fractions, including fractions >1.”
    • “Add and subtract fractions with the same denominator” (Year 7 content).

This plan also embeds speaking and listening skills, vocabulary development, and reasoning in line with English mastery.

Learning Objectives

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

• Accurately add and subtract fractions with the same denominator, using correct mathematical terminology.
• Explain their methods using precise English vocabulary relating to fractions.
• Apply their understanding to solve word problems involving fractional addition and subtraction.
• Demonstrate confidence in reading, writing, and speaking about fractions using appropriate language.

Resources

• Whiteboard and markers
• Individual whiteboards or mini slates for students
• Fraction strips or visual fraction models (printed or physical manipulatives)
• Worksheet with fraction problems and word problems (custom-designed)
• Vocabulary prompt cards: numerator, denominator, fraction, add, subtract, equal parts
• Timer or stopwatch
• Peer discussion cards with sentence stems

Lesson Structure

0–5 minutes: Starter Activity – Fraction Vocabulary Carousel

• Purpose: Reinforce key vocabulary and link Maths with English skills.
• Display 4 vocabulary cards around the room: numerator, denominator, add, subtract.
• Students circulate in pairs, spending 1 minute at each card discussing what it means and generating one sentence using the word.
• Teacher monitors, scaffolds language, and gathers examples for a quick oral recap.

5–15 minutes: Introduction to Adding and Subtracting Fractions with Same Denominator

• Recap: What is a fraction? Focus on denominator meaning “number of equal parts the whole is divided into.”
• Use visual aids (fraction strips/diagrams) to show fractions like 3/7 and 2/7.
• Demonstrate addition and subtraction of fractions with the same denominator using visuals:
  • Example: 3/7 + 2/7 = 5/7
  • Example: 5/7 − 2/7 = 3/7
• Emphasise that the denominator stays the same; only numerators change.
• Use clear sentence stems for students to repeat aloud, eg:
  “When we add fractions with the same denominator, we add the numerators and keep the denominator.”
• Check understanding through quick oral questioning (‘What is 4/9 + 3/9?’).

---

15–30 minutes: Guided Practice – Problem Solving with Fractions

• Hand out worksheets with 8 problems: 4 addition, 4 subtraction of fractions with the same denominator.
• Problems increase in complexity (e.g. 2/5 + 1/5, 7/12 − 3/12).
• Students work individually but can ask the teacher for clarification.
• After 10 minutes, students pair up to explain their answers, practising the frame sentence, e.g.
  • “I added the numerators 2 and 1 to get 3, and kept the denominator 5 unchanged, so 2/5 + 1/5 = 3/5.”
• Teacher circulates, listening and offering feedback on mathematical accuracy and language use.

---

30–40 minutes: Applying Maths and English – Word Problem Challenge

• Present 2 short, real-world word problems involving addition and subtraction of fractions with the same denominator.
• Example:
  Liam ate 3/8 of a pizza and Sophie ate 2/8. How much of the pizza did they eat together?
• Ask students to write a short paragraph explaining how they solved each problem, paying attention to sentence structure and spelling of key vocabulary.
• Encourage use of conjunctions (because, so, therefore) to improve cohesion in their explanations.
• Share and discuss two examples as a class, praising clear reasoning and language.

---

40–48 minutes: Interactive Quiz and Peer Teaching

• Conduct a rapid-fire quiz orally, asking quick fraction addition and subtraction questions.
• After each question, a volunteer explains the answer using full sentences and fraction vocabulary.
• Use peer-teaching: students who answer correctly explain to those who were unsure, promoting confidence and language development.

---

48–50 minutes: Plenary and Self-Assessment

• Ask students to rate their understanding on a scale of 1-5 and justify their rating in one sentence.
• Collect a quick ‘exit slip’ writing task:
  Write one thing you learned about adding or subtracting fractions today.
• Provide positive feedback and preview next lesson (adding and subtracting fractions with different denominators).

---

Assessment

• Formative assessment through observation during pair and class discussions and during worksheet completion.
• Oral assessments during the interactive quiz and peer teaching.
• Written assessment via the explanation paragraphs and exit slips.
• Use of vocabulary and clarity of explanation will be considered alongside computational accuracy.

---

Differentiation and Support

• Provide fraction strips and visual aids throughout lesson for concrete understanding.
• Use sentence starters for English language support for EAL or lower ability learners.
• Offer extension problems with mixed fractions or improper fractions for more able students.
• Encourage peer support during paired activities.
