Subject & verb agreement worksheets | Worsheets library - Free Printable

Explanation:
We need to fill in each blank with the correct verb form that matches the subject and the given infinitive (the base verb in parentheses). Remember:
- For singular subjects (he, she, it, or a singular noun like *Angela*, *the teacher*), we usually add -s or -es to the verb (present simple tense).
- For plural subjects (they, we, the children, the boys, etc.), we use the base form of the verb (no -s/-es).
- Also watch for special cases like verbs ending in -y, -ch, -sh, -x, -o, or -s — they may need -es.

Let’s go one by one:

1. The children ______ Pokémon cards. (to collect)
→ “The children” is plural → use base form: collect
✔ *The children collect Pokémon cards.*

2. Angela ______ ketchup on her eggs. (to put)
→ “Angela” is singular (she) → add -s: puts
✔ *Angela puts ketchup on her eggs.*

7. You ______ excellent spaghetti sauce. (to make)
→ “You” (singular or plural) always takes base form → make

8. She ______ really fast for her age. (to type)
