What mastery looks like

  • Identify 'play' as the root in 'played', 'playing', 'player'
  • Explain that '-ful' in 'careful' means 'full of care'
  • Use '-ness' and '-er' to form nouns from root words: 'sad → sadness', 'teach → teacher'

Check your understanding

When Root Words & Inflections sees words like "play," "plays," "played," and "playing," do they understand they all come from the same root word and can they use each form correctly?
