Lesson 17: Teacher Guide & Master Solutions
Article Usage • "An" with Vowel Sounds
Pedagogical Purpose & Classical Foundations:
Children discover the euphonic reason for an. Originating from Old English ān ("one"), English retains the final nasal consonant -n before vowel sounds (an apple, an ox) to prevent hiatus (an awkward vocal glottal catch between vowels). Ensure students speak and hear the smooth acoustic blend before writing.
Section A: Model Oral Reading & Copywork:
1. The man has an ax. (Declarative statement: capitalized The, period at the end).
2. Have you an apple? (Interrogative question: auxiliary verb inversion Have you..., question mark at the end).
Section B: Sentence Composition Exemplars (Accept equivalent complete sentences):
1. an eye → The eagle has a keen eye. / A speck of dust flew into an eye.
2. an ear → The rabbit twitched an ear at the sound. / The dog has a brown spot on an ear.
3. an inkstand → Grandfather placed an inkstand upon the wooden desk.
4. an iron ring → The blacksmith forged an iron ring for the wagon.
5. an ox → The sturdy farmer plowed his field with an ox.
6. an overcoat → Father wore an overcoat during the chilly morning walk.
Charlotte Mason Oral & Dictation Drill:
Read these three short sentences aloud once and ask the student to repeat and write them from memory:
• "The boy saw an owl in the oak tree."
• "May I borrow an inkstand?"
Verify that every sentence starts with a capital letter, preserves an before vowels, and closes with correct punctuation.
