      Spelling words with the suffixes -sion and -ssion

      Lesson details

      Learning outcome

      I can spell words with the suffixes -sion and -ssion.

      Key learning points

      1. The /shun/ sound can be spelt four different ways: -tion, -cian, -sion and -ssion.
      2. The /shun/ sound is sometimes spelt 'sion' or 'ssion'.
      3. The suffix -sion is used for the /shun/ or /zhun/ sound when the root word ends in 'd', 'de' or 'se'.
      4. The suffix -ssion is used for the /shun/ sound when the root word ends in 'ss' or 'mit'.
      5. How to spell the curriculum words: profession and develop

      Keywords

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

      • Suffix - a letter or group of letters added to the end of a word to change its meaning

      • Noun - a naming word for people, places or things

      • Verb - a doing, being or having word

      Common misconception

      Some pupils may not know the related root word or see how they are connected.

      Put the /shun/ word and the associated root word into a simple sentence to help secure their meaning. This will help pupils see the connections in meaning and spelling between the words.

      Teacher tip

      Allow pupils to investigate the spelling patterns. Give them word cards with a range of /shun/ spellings on them; ask pupils to decide how to group the words and explain the rationale for it. Ask them to say the word in a full sentence and identify the root word to support.
