Mastering English Spelling

Key ideas in Mastering English Spelling
- A single consonant allows the vowel to say its own name (long sound)
- Doubling only happens when the final beat of the word is stressed
- Double consonants act as a wall to keep the vowel sound short
- Words ending in a weak beat like 'open' do not get a double letter
- How doubling a consonant preserves the short vowel sound
- The relationship between word rhythm (stress) and doubling consonants
- One consonant after a vowel usually signals a long vowel sound
- Two consonants after a vowel usually signal a short vowel sound
- Check if the word has one short vowel followed by one consonant
- Double the final letter to protect that short vowel sound
- Add the ending like -ed or -ing
- Predicting the vowel sound based on the consonant count
- The decision process for doubling a letter in a single-beat word
- Only words with a single vowel before the consonant get a double letter
- Vowel teams like 'oa' or 'ee' already protect the sound and don't need a double
- Identifying which words require a double letter based on their pattern
