🎯 Rule to Remember:

We use:
- “An” before words that start with a vowel sound (a, e, i, o, u — or sometimes silent consonants like “h” in “hour”).
- “A” before words that start with a consonant sound.

> 💡 Important: It’s about the SOUND, not just the letter. For example:
> - “An hour” → because “hour” starts with a vowel *sound* (“our”).
> - “A university” → because “university” starts with a “yoo” sound (like “you”), which is a consonant sound.

But for Grade 1, we usually go by the first letter unless it's a tricky word like “hour” or “honest”. In this worksheet, all words follow the basic rule based on the first letter.

- pencil → starts with ‘p’ → consonant → a
- insect → starts with ‘i’ → vowel → an
- mask → starts with ‘m’ → consonant → a
- inkpot → starts with ‘i’ → vowel → an
- computer → starts with ‘c’ → consonant → a
- owl → starts with ‘o’ → vowel → an
- ear → starts with ‘e’ → vowel → an

- elephant → starts with ‘e’ → vowel → an
- eye → starts with ‘e’ → vowel → an
- ox → starts with ‘o’ → vowel → an
- yacht → starts with ‘y’ → consonant sound (“yuh”) → a

> 🧠 Note: “Yacht” starts with ‘y’, but since it makes a consonant sound (like “yuh”), we use “a”.
