Fill in the blanks with "a" or "an" using the provided images as clues.

Let’s go step by step.

We are filling in the blanks with either a or an.

Rule:
- Use a before words that start with a consonant sound (like b, c, d, f, g, etc.).
- Use an before words that start with a vowel sound (a, e, i, o, u).

Now let’s check each word:

1. cat → starts with “c” (consonant) → a cat
2. dog → starts with “d” (consonant) → a dog
3. nose → starts with “n” (consonant) → a nose
4. apple → starts with “a” (vowel) → an apple
5. eagle → starts with “e” (vowel) → an eagle
6. girl → starts with “g” (consonant) → a girl
7. leg → starts with “l” (consonant) → a leg
8. ear → starts with “e” (vowel) → an ear
9. octopus → starts with “o” (vowel) → an octopus
10. zebra → starts with “z” (consonant) → a zebra

Now the second column:

11. uncle → starts with “u” — but here it sounds like “uh”, which is a vowel sound → an uncle
12. pineapple → starts with “p” (consonant) → a pineapple
13. eraser → starts with “e” (vowel) → an eraser
14. shirt → starts with “s” (consonant) → a shirt
15. chair → starts with “ch” (consonant sound) → a chair
16. tree → starts with “t” (consonant) → a tree
17. ice cream → starts with “i” (vowel) → an ice cream
18. man → starts with “m” (consonant) → a man
19. ring → starts with “r” (consonant) → a ring
20. teacher → starts with “t” (consonant) → a teacher

Double-checking tricky ones:
- “uncle” → /ʌ/ sound → vowel → an ✔️
- “eraser” → /ɪ/ sound → vowel → an ✔️
- “ice cream” → /aɪ/ → vowel → an ✔️

All good!
