      Spelling words with the prefixes de-, re-, sub-, super-, inter-, anti- and auto-

      Lesson details

      Learning outcome

      I can spell a range of words with the prefixes de-, re-, sub-, inter-, super-, anti- and auto-.

      Key learning points

      1. A prefix is a letter or group of letters at the start of a word which changes its meaning.
      2. The prefix de- can mean ‘undo’ and re- can mean ‘again’.
      3. The prefix sub- can mean ‘under’ or ‘nearly’ and super- can mean ‘above’ or ‘larger’.
      4. The prefix inter- can mean ‘between’, anti- mean ‘against’ and auto- mean ‘self’ or ‘own’.
      5. How to spell the curriculum words: opposite, average, interrupt and lightning.

      Keywords

      • Prefix - a letter or group of letters added to the start of a root word to change its meaning

      • Root word - the base word from which other words are formed often by adding prefixes or suffixes

      Common misconception

      Pupils may think every word with a prefix will have a recognisable root word.

      Show that some roots we don't recognise may have Latin roots that we don't know. We can call this a 'stem' or a 'root'. Recognising the prefix can still help with spelling and understanding.

      Teacher tip

      You could play a definitions game as a whole class, where children provide a definition and challenge the class to find the right word.
