Analysing Word Parts

Overview

Lesson 3 of 4 in the unit “Word Parts: Prefixes and Suffixes”. Students apply morphology and sentence context to decode unfamiliar vocabulary in a text about online communication and school teamwork, then use precise vocabulary in their own writing.

Learning intentions

• WALT identify prefixes, bases and suffixes in words.
• WALT combine word-part clues with sentence context to predict meaning.
• WALT check predictions using a glossary or dictionary.
• WALT use newly analysed vocabulary accurately in writing.

Success criteria

• I can colour-code or underline the prefix, base and suffix.
• I can use word parts and the sentence to predict a word’s meaning.
• I can check and revise my prediction with a reference tool.
• I can explain how a word part helps me understand or spell a word and use the word in a sentence.

Curriculum links

• Reading comprehension: making meaning from texts and integrating information.
• Vocabulary acquisition: decoding unfamiliar words using morphology and context.
• Language knowledge: recognising word parts, word classes and spelling patterns.
• Writing precisely: selecting vocabulary for a clear purpose and audience; foundations for NCEA close reading and crafted writing.

Lesson structure (50 minutes)

1. 0–5 minutes – Retrieval warm-up Open with the retrieval warm-up and display six familiar words from Lessons 1–2. Students use mini-whiteboards to identify the prefix or suffix, base word and word class; quickly reveal answers and address misconceptions.

2. 5–15 minutes – Teacher modelling Use the modelling sequence to model notice parts, say parts, blend, predict, read the sentence, confirm or revise. Think aloud with unhelpful, rereading, careless, disagreement and overconfident, showing that a word may contain more than one affix and that word-part meanings are clues, not perfect formulas. Model checking one prediction in a dictionary or approved digital glossary.

3. 15–30 minutes – Guided reading and pair analysis Distribute the context-reading and morphology worksheet. Read the short adapted text about managing online communication and school teamwork aloud, one section at a time. Students echo-read, partner-read or use text-to-speech, then work in pairs to analyse misunderstood, respectful, irresponsible, cooperation, disagreement and reread. They colour-code morphemes, infer meanings and match words to definitions. Pause to discuss how context prevents incorrect guesses.

4. 30–42 minutes – Independent application Students complete the individual section of the context-clue analysis table. Year 9 students analyse four target words and write two sentences. Year 10 students analyse six words, identify a possible multiple meaning or limitation of the word-part strategy, and revise a short paragraph by replacing vague vocabulary with precise, morphologically related words. Encourage dictionary or glossary checking before finalising answers.

5. 42–47 minutes – Formative conferencing Confer with selected students while they work, asking: “What part helped you?”, “What did the sentence tell you?” and “How did you check?” Collect one completed word analysis and one sentence from each student, or photograph selected work for review.

6. 47–50 minutes – Share and plenary Return to the plenary prompts. Invite two or three students to share a useful word-part clue and explain how context confirmed or changed their prediction. Students complete the sentence: “A word-part strategy is useful because…, but I still need to…”

Resources

• the complete lesson slide deck
• the context-reading and morphology worksheet
• Mini-whiteboards and pens
• Highlighters or colour overlays
• Dictionaries or approved digital glossary
• Text-to-speech or audio version of the adapted text
• Headphones, if available
• Morpheme bank and word tiles for students needing additional support

Assessment

• Observe retrieval responses, pair explanations and colour-coded morpheme analysis.
• Listen for evidence-based explanations linking word parts and sentence context.
• Collect one analysis and one sentence to check decoding, meaning, checking and accurate use.
• Note whether students can recognise when a word-part prediction needs revision.

Differentiation

• Present the text in short sections with headings, generous spacing and no unnecessary decoration. Offer teacher reading, repeated reading, partner reading and text-to-speech; allow dyslexia-friendly fonts, colour overlays and extra processing time.
• Preteach misunderstood and cooperation. Provide a morpheme bank, word tiles, pronunciation support and sentence frames such as “I think ___ means ___ because ___.”
• Allow students to underline, colour-code, point to word parts or give a spoken explanation. Use gestures or movement to reinforce meanings and pair students strategically.
• For Year 9, use transparent, high-frequency words and four target items. For Year 10, include less transparent vocabulary, require evidence from context and ask students to explain limits or multiple meanings.
