Using and applying all the rules for the suffix -ous

I can spell a range of words using the suffix -ous.

Lesson details

Key learning points

  1. There are four spelling rules when adding -ous to a root word.
  2. Some words ending in -ous do not have a root word we recognise.
  3. When you hear the ‘ee’ sound before -ous, the most likely spelling is an ‘i’, but it is sometimes an ‘e’.
  4. How to spell the curriculum words: guard, exercise and decide.

Common misconception

Pupils may not know or understand the meaning of many words encountered in the lesson.

Put all unfamiliar vocabulary into simple sentences to expose children to the meaning. Make links to root words where possible.

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 root word

  • Pronunciation - the way in which a word is spoken

  • Adjective - describes a noun

You can set the words for children to practise independently based on your knowledge or allow them to select themselves. Help them to identify independent practice strategies which are efficient and effective.
