Lesson details

Key learning points

  1. It is common to see a ‘c’ or a ‘t’ before the suffix -ial.
  2. The /shul/ ending can be spelt -cial or -tial.
  3. If the letter before the /shul/ ending is a consonant, -tial is usually used.
  4. If the letter before the /shul/ ending is a vowel, -cial is usually used.
  5. How to spell the curriculum words: separate, popular and opposite.

Keywords

  • Consonant - a sound that is made by blocking air in the mouth with the teeth, tongue, lips or palate

  • Vowel - a speech sound produced with an open mouth

  • 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

Common misconception

The wrong vowels are used in curriculum words: separate, popular and opposite.

Saying the words slowly 'how they are spelt' is a useful strategy to remember these tricky spellings, e.g. sep -ar -ate.

Whilst exceptions to the rule are introduced in the lesson, focus on the words that follow the rules primarily, as there is time in upper KS2 to focus on exceptions.
