As at the syllable juncture stage, words with a schwa are the source of numerous spelling difficulties because sound is no help. Therefore, the spellingmeaning connection needs to be stressed for these types of words. Have students sort the words into base words and related suffixed or derived words. Then address the key points below. 2.1 Easiest word list (Recommended for intermediate) 2.2- Average word list (Recommended for late intermediate) 2.3- Challenge word list (Recommended for advanced intermediate or middle) Key Points: Students should initially have access to both the base word and the related suffixed or derived words (relative/relativity; oppose/opposition) After the related words are matched up, ask students o Do the vowel sounds in the accented syllables of the word pairs change? (students should respond YES). o Does the spelling of the vowel change? (NO) o Remind students that this is true because the words are related in meaning (spelling-meaning connection).
