Defining Words

English · Vocabulary · conceptual

Define words by category and by one or more key attributes (e.g., 'a duck is a bird that swims'), making real-life connections between words and their use

What mastery looks like

  • Define 'tiger' as 'a large cat with stripes' — naming category and key attribute
  • Connect the word 'cozy' to real-life examples: places at home that feel cozy
  • Sort words into categories and explain why each word belongs

Check your understanding

Can Defining Words explain what a word means by saying what type of thing it is and what makes it special — for example, "a penguin is a bird that can't fly but is great at swimming"?
