Objective and success criteria
Students will: What prefixes mean: pre-, sub-, inter-, trans- and more.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Prefixes and suffixes
Leads to: Making opposites with un-, in-, im-, il-, ir-, dis- and non-; Advanced prefixes: ante-, hyper-, hypo-, pseudo-, retro-…
Materials: Word cards, A thesaurus or dictionary, A short text with the target words, Mini whiteboards, A short model text on the board, Printed student sheet (below).
Warm-up · 4 min
- Quick retrieval from earlier learning (Prefixes and suffixes). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Which prefix makes a real word from "behave", meaning "not" or "wrongly"? (misbehave / disbehave / inbehave / unbehave) → misbehavePrompt: un-, dis-, mis-, in-, im-, il- and ir- can all mean 'not'.
- What does this prefix mean? tri- (as in tricycle, triangle) (two / four / three / ten) → threePrompt: Look at the example words. What do they have in common?
- What does this suffix mean? -er / -or (as in teacher, actor) (more than / the state of / a person who / not) → a person whoPrompt: Look at the example words.
Hook · 3 min
- Show an interesting word in a sentence and ask what it might mean from the clues around it.
- Share the objective: What prefixes mean: pre-, sub-, inter-, trans- and more. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What does the prefix "semi" mean? (as in semifinal, semicolon, semicircle)
- Step 1: Knowing what a prefix means helps you work out unfamiliar words that contain it.
- Step 2: semi means "half", as in semicircle, semifinal, semicolon.
- Step 3: So the answer is: half
- Answer: half
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What does the prefix "sub" mean? (as in subway, subtitle, submerge) (many / again / under / together) → underPrompt: What do the example words have in common?
- Which word contains a prefix that means "together"? (cooperate / decode / multitask / exclude) → cooperatePrompt: Split each word into parts. Which part could mean "together"?
You do: independent practice · 7 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- These words share a prefix that means "across". Type it. translate, transplant, transatlantic → transPrompt: Look for the letters that appear in every word.
- What does the prefix "trans" mean? (as in transparent, transplant, transatlantic) (many / half / together / across) → acrossPrompt: What do the example words have in common?
Watch out for
- Picking a "bigger" synonym that doesn't fit the meaning.
- Ignoring the clues in the rest of the sentence.
Support and stretch
Support
- Review first: Prefixes and suffixes.
- Use concrete materials: word cards.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: Making opposites with un-, in-, im-, il-, ir-, dis- and non-; Advanced prefixes: ante-, hyper-, hypo-, pseudo-, retro-….
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
