Let’s go through each sentence one by one and find the word with a
long vowel sound.
A long vowel sound means the vowel says its name — like “ee” in “cheese”, or “ay” in “day”.

1. I like grilled cheese sandwiches.
Options: *sandwiches*, *cheese*
→ “Cheese” has the long “e” sound (says “eee”).
✔ Answer:
cheese
---
2. Floss your teeth every day.
Options: *teeth*, *every*
→ “Teeth” has the long “e” sound (“tee-th”).
“Every” has short “e” sounds.
✔ Answer:
teeth
---
3. The first day of the week is Sunday.
Options: *first*, *Sunday*
→ “Sunday” has a long “u” sound? Wait — actually, “Sun-day” — the “u” is short. But “day” has a long “a”! Oh — but “day” isn’t an option. Let’s check again.
Wait — “Sunday” — the “u” is short, but the “ay” at the end makes it long A? Actually, “Sunday” = /ˈsʌn.deɪ/ — so the second syllable has long “a”.
But let’s compare to “first” — that’s short “i”.
So “Sunday” has a long vowel sound in the second syllable.
✔ Answer:
Sunday
*(Note: Some might argue “day” is the long vowel part — since “Sunday” contains “day”, it counts.)*

4. Mom will agree to drive us to game.

Options: *tree*, *cast*

“Cast” has short “a”.
✔ Answer:

6. We went to the park, and the place was so clean.
Options: *park*, *clean*

✔ Answer:
clean

---
8. I have thrown out all my old papers.
Options: *have*, *thrown*
