Wheeler Page 32

Pedagogical Purpose: Synthesizes the four foundational spelling rules of English suffixation. Students must discriminate between vowel teams, CVC roots, consonant clusters, and silent-e bases.

ORTHOGRAPHIC MATRIX

Group & Target	Base Words	Built Word Key	Orthographic Governing Rule	Phonological Reason
Group 1 (+ -ing)	clear, steer, gain, rain	clearing steering gaining raining	Vowel Digraph Rule: Two vowel letters precede final consonant. No doubling.	Long vowel or diphthong is already established; extra consonant would distort syllable boundaries.
Group 2 (+ -ed)	trim, pin, peg, tag	trimmed pinned pegged tagged	1-1-1 Doubling Rule: 1 syllable + 1 short vowel + 1 final consonant = double letter.	Consonant doubling closes the initial syllable, protecting the short vowel sound /ɪ/, /e/, /æ/.
Group 3 (+ -ing & -ed)	bend, tend, pass, mind	bending / bended tending / tended passing / passed minding / minded	Consonant Cluster Rule: Words ending in two consonants (-nd, -ss) add suffixes directly.	The short or diphthongal vowel is already closed by two consonants; no further protection is needed.
Group 4 (+ -ing)	name, leave, weave, time, note, store, cure	naming leaving weaving timing noting storing curing	Silent -e Drop Rule: Drop final silent -e before vowel suffixes.	The incoming vowel suffix replaces the function of final -e in maintaining syllable structure.

EXERCISE 5: SOCRATIC DISCOVERY MODEL RESPONSES

a. clear & rain: They have two vowels (vowel team ea, ai) before the final consonant, so the consonant does not double.

b. trim & tag: They are one-syllable words with one short vowel and one consonant (1-1-1 rule), so the final letter doubles to protect the short vowel.

c. leave, weave, cure: The silent letter e must be dropped before adding the vowel suffix -ing.

d. bend & pass: They already end in two consonants (-nd, -ss), which already keep the vowel sound closed.

GUIDED ORAL PRACTICE • Socratic Teacher Script

Oral Prompt 1 (Vowel Teams vs. CVC)

“Listen carefully: pin becomes pinned, but rain becomes raining. Why does rain not have two n's? Because ai is a vowel team!”

Oral Prompt 2 (Silent -e Dropping)

“What happens to the silent -e in name and cure when we add -ing? The -e steps aside because -ing begins with a vowel!”

Dictation Sentence 1 (trimming, steering)

“The captain was steering the boat while trimming the sail.”

Dictation Sentence 2 (naming, passing)

“She was naming each bird passing over the green field.”
