Sure! Let’s solve this capitalization worksheet step by step.

The task is: “Rewrite the sentences with the correct capital letters.”

We need to apply basic English capitalization rules:

Capitalize the first word of every sentence.
Capitalize proper nouns (names of people, pets, specific places, etc.).
Do not capitalize common nouns (like “tree,” “moon,” “clock,” “cookies”) unless they start the sentence or are part of a proper name.

---

Let’s go sentence by sentence:

---

1. my grandma bakes cookies.
→ “My” should be capitalized because it’s the first word of the sentence.
→ “Grandma” — here, “grandma” is used as a common noun (not a name), so it stays lowercase unless addressing her directly (e.g., “I love you, Grandma!”). In this context, it’s not being used as a title/name, so it remains lowercase.
Corrected: My grandma bakes cookies.

---

2. the big tree has many leaves.
→ “The” must be capitalized as the first word.
→ “Big tree,” “leaves” — all common nouns, no names → no capitalization needed.
Corrected: The big tree has many leaves.

---

3. the moon is bright at night.
→ “The” capitalized.
→ “Moon” — in general usage (not referring to Earth’s Moon in a scientific/astronomical context), it’s lowercase. If we were talking about “the Moon” as a celestial body specifically, some style guides capitalize it — but for elementary worksheets, it’s usually left lowercase.
Corrected: The moon is bright at night.

*(Note: In advanced writing, “Moon” is often capitalized when referring to Earth’s natural satellite. But for this level, lowercase is acceptable and expected.)*

---

4. my best friend is sara.
→ “My” capitalized.
→ “Sara” is a person’s name → must be capitalized.
Corrected: My best friend is Sara.

---

5. my teddy bear is named fluffy.
→ “My” capitalized.
→ “Fluffy” is the name of the teddy bear → it’s a proper noun → must be capitalized.
Corrected: My teddy bear is named Fluffy.

---

6. the clock says it's bedtime.
→ “The” capitalized.
→ “Clock,” “bedtime” — common nouns → no capitalization needed.
Corrected: The clock says it's bedtime.

---

Final Answers:



1. My grandma bakes cookies.
2. The big tree has many leaves.
3. The moon is bright at night.
4. My best friend is Sara.
5. My teddy bear is named Fluffy.
6. The clock says it's bedtime.
