Lesson details
Key learning points
- It is common to see a ‘c’ or a ‘t’ before the suffix -ial.
- The /shul/ ending can be spelt -cial or -tial.
- If the letter before the /shul/ ending is a consonant, -tial is usually used.
- If the letter before the /shul/ ending is a vowel, -cial is usually used.
- 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.
