Learning journey

Your child is learning how words are built and connected — discovering how root words change with different endings (like look/looks/looked) and learning to define words by describing what category they belong to and their key features.

Evidence of understanding

  • 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'

Assessment prompt

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?
