INSTRUCTOR REFERENCE KEY |
| Word | Vowel | IPA | Phonogram Pattern | Orthographic & Etymological Notes |
|---|---|---|---|---|
| 1. same | ā | /seɪm/ | split digraph a_e | Base CVCe. Silent final e makes preceding vowel long. |
| 2. frame | ā | /freɪm/ | fr- + a_e | Initial blend fr- with long ā. |
| 3. flame | ā | /fleɪm/ | fl- + a_e | Initial blend fl- with long ā. |
| 4. brave | ā | /breɪv/ | br- + a_e | Initial blend br-; English words do not end in v without silent e. |
| 5. strange | ā | /streɪndʒ/ | str- + -ange | Triple blend str-; soft g (/dʒ/) conditioned by silent e. |
| 6. changing | ā | /ˈtʃeɪndʒɪŋ/ | change + -ing | Silent e dropped before -ing; soft g preserved by vowel i. |
| 7. vain | āi | /veɪn/ | ai vowel team | Homophone with vane and vein; digraph ai = /eɪ/. |
| 8. stain | āi | /steɪn/ | st- + ai | Initial blend st- + vowel digraph ai. |
| 9. chain | āi | /tʃeɪn/ | ch- + ai | Voiceless palatal affricate ch- + ai phonogram. |
| 10. brain | āi | /breɪn/ | br- + ai | Initial blend br- with vowel team ai. |
| 11. frail | āi | /freɪl/ | fr- + ai | Initial blend fr-; adjective meaning delicate or easily broken. |
| 12. praising | āi | /ˈpreɪzɪŋ/ | praise + -ing | Silent e dropped; medial s pronounced voiced /z/. |
| 13. clam | ă | /klæm/ | cl- + short ă | Initial blend cl- + short ă (/æ/) closed syllable. |
| 14. lamb | ă | /læm/ | silent b (-mb) | Historical silent b; short ă closed by bilabial nasal /m/. |
| 15. latch | ă | /lætʃ/ | -tch trigraph | Spelling rule: trigraph -tch follows a single short vowel. |
| 16. snatch | ă | /snætʃ/ | sn- + -tch | Initial blend sn- with short ă + -tch. |
| 17. scratch | ă | /skrætʃ/ | scr- + -tch | Triple blend scr- with short ă + -tch. |
| 18. sprang | ă | /spræŋ/ | spr- + -ang | Triple blend spr- + nasal digraph -ng (past of spring). |
| 19. scene | ē | /siːn/ | silent c + e_e | Initial digraph sc- = /s/; split digraph e_e = /iː/. |
| 20. theme | ē | /θiːm/ | th- + e_e | Voiceless digraph th- + split digraph e_e. |
| 21. speech | ē | /spiːtʃ/ | sp- + -eech | Vowel team ee = /iː/ followed by affricate -ch. |
| 22. breeze | ē | /briːz/ | br- + -eeze | Vowel team ee followed by voiced fricative -ze (/z/). |
| 23. freezing | ē | /ˈfriːzɪŋ/ | freeze + -ing | Base freeze drops silent final e before suffix -ing. |
| 24. cheese | ē | /tʃiːz/ | ch- + -eese | Digraph ch- + ee; final -se sounds voiced /z/. |
• The Principle: English avoids redundant vowel letters in suffixation. When adding a suffix beginning with a vowel (-ing, -ed, -er, -able), a single silent final e is dropped.
• Wheeler's Text Examples: praise → praising, freeze → freezing, and change → changing. The student must understand that the dropped e is replaced in function by the vowel of the suffix.
• Condition for Soft g: In changing, the soft g (/dʒ/) is preserved because the suffix -ing begins with i (letters e, i, y soften c and g).
• Contrast with Silent b and -tch: Note the silent b in lamb (etymological Germanic *lambaz), and the trigraph -tch in latch, snatch, scratch which strictly follows a single short vowel.
1. Vowel Column Categorization (6 pts): Accurately writes all 24 words in their designated vowel column with correct spelling.
2. Silent-E Dropping Rule (5 pts): Demonstrates complete understanding that silent e is dropped before vowel suffix -ing.
3. Penmanship & Midline (5 pts): Writing sits firmly on 26px baseline; lowercase letters align with 13px dashed midline.
4. Orthographic Conventions (4 pts): Accurately spells silent-letter words (lamb, scene) and trigraphs (latch, snatch, scratch).
• Orthographic Law: “What happened to the 'e' when 'freeze' became 'freezing'? Why don't we write 'freezeing'?” (Rule: drop silent final 'e' before a vowel suffix).
• Silent Letter Exploration: “Can you hear the 'b' in 'lamb'? What about the 'c' in 'scene'? Why do we keep them in spelling?” (Historical etymology and word distinction).
• Trigraph Rule: “Why do 'latch', 'snatch', and 'scratch' end in '-tch' while 'speech' ends in '-ch'?” (Rule: '-tch' follows a single short vowel; '-ch' follows a vowel team like 'ee').
