Objective and success criteria
Students will: Advanced prefixes: ante-, hyper-, hypo-, pseudo-, retro-….
- 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: What prefixes mean: pre-, sub-, inter-, trans- and more; Decoding advanced words from their roots
Leads to: the next skill in this area.
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 · 5 min
- Quick retrieval from earlier learning (What prefixes mean: pre-, sub-, inter-, trans- and more; Decoding advanced words from their roots). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What does the prefix "sub" mean? (as in subway, submarine, subtitle) (together / half / many / under) → underPrompt: What do the example words have in common?
- Which word contains a prefix that means "against"? (multitask / antifreeze / transplant / intercept) → antifreezePrompt: Split each word into parts. Which part could mean "against"?
- These words share a prefix that means "again". Type it. rebuild, replay, reheat → rePrompt: Look for the letters that appear in every word.
Hook · 5 min
- Show an interesting word in a sentence and ask what it might mean from the clues around it.
- Share the objective: Advanced prefixes: ante-, hyper-, hypo-, pseudo-, retro-…. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What does the prefix "hypo" mean? (as in hypothermia, hypodermic, hypothesis)
- Step 1: Knowing what a prefix means helps you work out unfamiliar words that contain it.
- Step 2: hypo means "under, below", as in hypothermia, hypodermic, hypothesis.
- Step 3: So the answer is: under, below
- Answer: under, below
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 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 "intra" mean? (as in intramural, intranet, intravenous) (within / together, with / before / false) → withinPrompt: What do the example words have in common?
- Which word contains a prefix that means "within"? (intramural / extraterrestrial / synthesis / retrograde) → intramuralPrompt: Split each word into parts. Which part could mean "within"?
You do: independent practice · 10 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 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which word contains a prefix that means "beyond, extremely"? (hypersensitive / equilibrium / intravenous / ultrasound) → ultrasoundPrompt: Split each word into parts. Which part could mean "beyond, extremely"?
- These words share a prefix that means "backwards". Type it. retrofit, retrospect, retrograde → retroPrompt: Look for the letters that appear in every word.
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: What prefixes mean: pre-, sub-, inter-, trans- and more.
- 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
- 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.
