Warm-up · 6 min

  • Quick retrieval from earlier learning (Greek roots: path, phil, phob, psych, poly and more). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. What does the Greek root "mono" mean? (as in monorail, monotone, monologue) (feeling, suffering / one / many / shape, form) → onePrompt: What do the example words have in common?

  3. These words share a Greek root that means "people". Type it. epidemic, demographic, pandemic → demPrompt: Look for the letters that appear in every word.

Hook · 6 min

  • Show an interesting word in a sentence and ask what it might mean from the clues around it.
  • Share the objective: Greek roots: arch, crypt, gen, chrom, derm, tox and more. Read the success criteria together.

I do: model it · 12 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: What does the Greek root "derm" mean? (as in epidermis, dermatologist, hypodermic)
  • Step 1: Knowing what a Greek root means helps you work out unfamiliar words that contain it.
  • Step 2: derm means "skin", as in dermatologist, epidermis, hypodermic.
  • Step 3: So the answer is: skin
  • Answer: skin
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 12 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. What does the Greek root "chrom" mean? (as in chromatic, monochrome, chromosome) (colour / skin / all / rule, chief) → colourPrompt: What do the example words have in common?
  2. Which word contains a Greek root that means "colour"? (toxin / chromosome / monarch / panorama) → chromosomePrompt: Split each word into parts. Which part could mean "colour"?

You do: independent practice · 17 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 · 7 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. These words share a Greek root that means "birth, origin, kind". Type it. genesis, generation, genetic → genPrompt: Look for the letters that appear in every word.
  2. What does the Greek root "soph" mean? (as in sophisticated, philosophy, sophomore) (movement / hidden / birth, origin, kind / wisdom) → wisdomPrompt: 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: Greek roots: path, phil, phob, psych, poly 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

  • Move on to: Decoding advanced words from their roots.
  • 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.
