This worksheet challenges students to convert a list of singular nouns, such as 'spoon' and 'fox', into their plural counterparts.

Let's solve the task step by step.

The goal is to change each singular noun into its plural form. We'll go through each word and apply the standard rules for forming plurals in English.

🔹 General Rules for Plural Nouns:

1. Most nouns: Add -s
→ *girl* → *girls*, *dog* → *dogs*

2. Nouns ending in -s, -sh, -ch, -x, -z: Add -es
→ *box* → *boxes*, *church* → *churches*

3. Nouns ending in -y:
- If preceded by a consonant, change -y to -ies
→ *key* → *keys* (wait! "key" ends in 'y' but after consonant? Actually, it’s “key” → “keys” because it’s pronounced with a long ‘e’ sound, so we just add -s)
→ But baby → babies, city → cities
- If preceded by a vowel, just add -s
→ *boy* → *boys*, *day* → *days*

4. Nouns ending in -f or -fe: Often change to -ves
→ *leaf* → *leaves*, *knife* → *knives*

5. Irregular plurals: Some words don’t follow rules
→ *child* → *children*, *man* → *men*, *mouse* → *mice*, *person* → *people*

6. Words that are the same in singular and plural
→ *sheep*, *deer*, *fish* (in some contexts)

7. Words ending in -o: Usually add -s, but some add -es
→ *photo* → *photos*, *potato* → *potatoes*
