Hook · 5 min

  • Read a short passage with no punctuation and let the class hear why it's confusing.
  • Share the objective: Essential or non-essential? Commas with appositives and clauses. 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: Which option completes the sentence correctly? The novelist ___ won the Nobel Prize in 1993.
  • Step 1: Non-essential (extra) information is set off with commas; essential (identifying) information is not.
  • Step 2: Many novelists exist; the name identifies which one: no commas.
  • Step 3: So the answer is: Toni Morrison
  • Answer: Toni Morrison
  • 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.
  1. Is this sentence correct in formal written English? Students, who feel unwell, must see the nurse. (correct / incorrect) → incorrectPrompt: Remove the words. Do we still know exactly who or what is meant?
  2. Which option completes the sentence correctly? Mount Everest ___ is on the border of Nepal and China. (, the highest mountain on Earth, / the highest mountain on Earth) → , the highest mountain on Earth,Prompt: Remove the words. Do we still know exactly who or what is meant?

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.
