Adding the suffix -ise to words

I can turn adjectives and nouns into verbs using the suffix -ise.

Lesson details

Key learning points

  1. The suffix -ise often turns adjectives and nouns into verbs.
  2. When the root word ends in a consonant, we often just add the suffix.
  3. When the root word ends in a ‘y’, we remove the ‘y’ and add the suffix.
  4. A suffix is a letter or group of letters at the end of a word which creates another word and can change the word class.
  5. How to spell the curriculum words: probably, occasion and occasionally.

Common misconception

Pupils use the spelling 'ize' to represent the -ise suffix.

Explicitly reference the difference between how the word is spelt and how it is pronounced. In American English, the spelling -ize is used.

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

  • Adjective - describes a noun

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

  • Verb - a doing, being or having word

Use 'my turn, your turn' to help the pupils to practise saying the focus words in full sentences. This will help secure the meaning and word class for pupils.
