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 word class is this word? Use its suffix to decide. kindness
- Step 1: A suffix can change a word's class: kind (adjective) → kindness (noun) → kindly (adverb).
- Step 2: -ness turns an adjective (kind) into a noun.
- Step 3: So the answer is: noun
- Answer: noun
- 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 word class is this word? Use its suffix to decide. childhood (noun / verb / adjective / adverb) → nounPrompt: Find the suffix at the end of the word.
- Join the word and the suffix. Type the new word, spelled correctly. happy + ness → happinessPrompt: Does the word end in e or y?
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.
