      Spelling words with the prefixes co-, pre-, pro- and sus-

      Lesson details

      Learning outcome

      I can spell a range of words with the prefixes co-, pre-, pro- and sus-.

      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 prefixes co-, com- and con- mean ‘together’ or ‘with’.
      3. The prefix pre- means ‘before’ and pro- means ‘ahead’.
      4. A hyphen can join a prefix to a base word to avoid ambiguity in meaning or spelling.
      5. How to spell the curriculum words: complete, programme and develop.

      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

      • Hyphen - a hyphen can join a prefix to a base word to avoid ambiguity in meaning or spelling

      Common misconception

      Children may not remember double letters at the start of some words with prefixes, such as illogical or dissatisfied.

      Help the children to see that if they recognise the prefix and the base word, they can work out the spelling of the new word, as prefixes do not change the spelling of the root word.

      Teacher tip

      It may be helpful to display commonly used words using a hyphen to join the prefix, as these can be hard to learn and there isn't a clear rule about when they are used and when they aren't.
