Prefixes and Suffixes

---

Learning Objectives

• Word structure (Year 5, English - National Curriculum for England, Spelling: Words with prefixes and suffixes)
  Pupils should be taught to:

  • Add prefixes and suffixes appropriately when spelling, including those that require the root word to change (e.g., -fer, -ible, -able, -ation).
  • Recognise the difference between the meaning of different prefixes and suffixes and how they affect the grammatical function of a word.

• Vocabulary development
  Letters and Sounds (NC KS2 Spelling Programme), building on prior knowledge to understand the morphology of words.

Curriculum Links

• English - National Curriculum KS2 Spelling Programme of Study
  Pupils should be taught to:

  • Use further prefixes and suffixes and understand how to add them (e.g. -ly, -ful, -less, -ment).
  • Spell some words with ‘silent’ letters [e.g. knight, psalm, solemn].
  • Use knowledge of morphology and etymology to support spelling.

• English - Spelling, vocabulary, grammar and punctuation (Years 3-6)
  Pupils should consolidate their understanding of how affixes affect word meanings and grammatical role.

Duration

• 50 minutes

Resources

• Word cards with base words, prefixes, and suffixes (printed on coloured paper for easy sorting)
• Whiteboards and markers for brainstorming
• Worksheets for recording sorted words and new creations
• Large sorting mats or areas labelled “Prefixes” and “Suffixes”
• Timer or stopwatch

Lesson Structure

1. Starter (5 minutes)

• Engage and Activate Prior Knowledge
  Write base words on the board (e.g., happy, play, care, hope). Ask learners to shout out any prefixes or suffixes they know that can be added (e.g., unhappy, playful, careful, hopeful).
  Brief discussion: What happens to the word’s meaning or grammatical role when we add these parts?

Purpose: To refresh the concept of prefixes and suffixes and their impact on word meaning.

---

2. Introduction (8 minutes)

• Explicit Teaching: Prefixes and Suffixes Refresher
  Define prefixes (added to the start) and suffixes (added to the end).
  Show examples and highlight how the meaning or word class changes:
  • Prefix “un-” changes the meaning to the opposite (happy → unhappy).
  • Suffix “-ful” changes noun to adjective (help → helpful).
    Highlight exceptions or tricky transformations (e.g. double consonant for suffixes like -ing, -ed).

Visual support: Use colour coding on the board to separate base, prefix, and suffix.

3. Main Activity (30 minutes)

Part A: Sorting Activity (15 minutes)

• Activity: In groups of 4-5, learners receive shuffled word cards. They sort words into two categories on the mats: words with prefixes and words with suffixes.
• Challenge extension: Identify base words and underline/change colour on their cards.
• Guiding questions for groups:
  • Which part did you add? Start or end?
  • Does the prefix or suffix change the word’s meaning or its grammar role?
• Teacher role: Circulate, help clarify, ask probing questions, encourage accurate sorting.

---

Part B: Brainstorm and Create (15 minutes)

• Activity: Using a list of base words (displayed on the board and worksheet), groups brainstorm new words by adding different prefixes and suffixes they know.
• Example base words: care, play, joy, hope, act.
• Each group writes at least five new words on mini whiteboards, saying the word aloud and discussing meaning changes.
• Extension: Include tricky affixes such as -ation, -less, dis-, mis-, re-.

Purpose: To deepen understanding of how affixes change meaning and unlock creative word formation.

---

4. Plenary and Assessment (7 minutes)

• Class Discussion: Each group shares their favourite new word from the brainstorm and explains how the prefix or suffix changed the word’s meaning or grammatical use.

• Quick Quiz: Teacher verbally gives a base word plus an affix; students write the new word and its meaning on mini whiteboards for instant feedback.

• Formative Assessment: Teacher observes correct spellings, accurate categorisation, and explanations for affix impact.

---

Differentiation

• Support: Smaller groups with tailored scaffolding, highlighting common affixes and base words familiar to these learners. Use visuals to demonstrate meaning clearly.
• Challenge: Encourage advanced learners to use affixes from Latin or Greek roots, explain etymology where possible.
• Extension task: Create sentences using newly formed words focusing on correct grammatical use.

---

Homework Suggestion

• Find 5 new words at home or in reading materials that use prefixes or suffixes and write a sentence for each, underlining the affix.

---

Reflection Points for Teacher

• Did the students show clear understanding of the function of prefixes vs suffixes?
• Were they able to apply affixes creatively and correctly?
• Could students explain meaning changes confidently?
• Adjust future lessons to focus more on either spelling or meaning depending on gaps observed.

Notes for Teachers

This lesson is designed to be highly interactive and student-centred to reinforce morphological knowledge in line with the National Curriculum. The sorting activity is multisensory and collaborative, ideal for diverse learning styles. Brainstorming promotes word awareness and ownership, crucial at KS2 as students shift from learning to spell to spelling to learn.

By combining sorting, discussion, and application, this lesson supports both spelling accuracy and deeper vocabulary development—a key aim for Year 5 students preparing for upper KS2 demands.
