English · Phonics & Word Reading · procedural

Sign in to track this

What mastery looks like

  • Read words with common prefixes (dis-, mis-, re-, pre-) and suffixes (-ation, -ous, -ly) by identifying the root word first
  • Apply morphological knowledge to attempt unfamiliar words (e.g. recognise 'happy' inside 'unhappiness')
  • Explain how a prefix or suffix changes the meaning or word class of a root word (e.g. 'care' → 'careless' → 'carelessly')

Check your understanding

When Prefixes and suffixes sees a word like 'disappear' or 'comfortable', can they spot the root word and figure out what the prefix or suffix is adding to its meaning?
