Final answer:
The spelling errors in options a, b, c, and e suggest that Cameron needs further practice with the orthographic patterns for long vowel sounds. Option d is correctly spelled and does not demonstrate an error in sound-symbol correspondence for long vowels.
Step-by-step explanation:
The question identifies spelling errors that suggest a need for further practice with long vowel sound-symbol correspondences.
The options provided contain various representations of words where such spelling errors can occur. Evaluating each option:
- a. "smillig(n)" - This option indicates a misspelling where the intended word likely has a long vowel sound, but the orthographic pattern is not correct for representing that sound.
- b. "sangse" - This appears to be a misspelling that could involve an incorrect orthographic pattern for representing a long vowel sound. However, without a correct form, it's hard to determine the intent.
- c. "drce" - Similarly, this word is likely misspelled, suggesting difficulty with the correct vowel sound representation. This word is unrecognizable, making it difficult to correct without additional context
- d. "spent" - This word is spelled correctly and has a short vowel sound.
- e. "camferd" - This option shows a misspelling that suggests the student may have intended a word with a long vowel sound but did not use the correct orthographic pattern.
To indicate spelling errors that point towards difficulty with long vowel sound-symbol correspondences, options a, b, c, and e are most likely correct. Option d does not indicate such an issue.
