Spelling polysyllabic words with unstressed vowels

Lesson details

Learning outcome

I can spell polysyllabic words with unstressed vowels.

Key learning points

  1. In polysyllabic words, some vowels can be unstressed and hard to hear and spell.
  2. Saying the word how it is spelt can help to learn the spelling.
  3. Thinking of the root word and identifying prefixes and suffixes can help to learn the spelling.
  4. How to spell the curriculum words: variety, various, imagine and definite.

Keywords

  • Polysyllabic - describes a word that has more than one syllable

  • Vowel letters - the letters ‘a’, ‘e’, ‘i’, ‘o’, ‘u’ (and sometimes ‘y’) that represent vowel sounds

  • Unstressed - an unstressed sound is not emphasised or pronounced with much force

Common misconception

Children may use the wrong vowel letter when spelling words with unstressed vowels.

Stretching the word and saying it slowly, how it is spelt, can help pupils to remember the correct spelling.

Teacher tip

Give children a large selection of polysyllabic words and ask them to identify those with unstressed vowels. Ask them to come up with their own ideas of how to best remember the spellings. They could do this in groups.
