Grade 4 English worksheet helping students master capitalization rules for specific subjects, official titles, and brand names.

Let’s go through each sentence one by one and fix the capitalization based on the rules given:

Rules to remember:
- Titles are capitalized only if they’re part of someone’s name.
- Brand names are always capitalized.
- School subjects are not capitalized unless they’re a language (like English, Spanish, French).

1. My mom has met senator O’Brien.

→ “senator” is a title, but it’s not part of his name here — we don’t say “Senator O’Brien” as his full name in this context? Actually, wait — when you’re talking about a specific person with their title + last name, you DO capitalize it. So “Senator O’Brien” is correct.

✔ Fixed: My mom has met Senator O’Brien.

2. We studied president Lincoln in Social studies today.

→ “president” before “Lincoln” → should be capitalized because it’s part of his title/name: “President Lincoln”.

→ “Social studies” → not a language, so lowercase: “social studies”

✔ Fixed: We studied President Lincoln in social studies today.

3. I bought a mountain dew and some Pringles after my french class.

→ “mountain dew” → brand name → must be capitalized: “Mountain Dew”

→ “Pringles” → already correctly capitalized (brand)

→ “french class” → “French” is a language → must be capitalized

✔ Fixed: I bought a Mountain Dew and some Pringles after my French class.

4. The Mayor visited my Language arts class last week.

→ “Mayor” → if it’s used as a title before a name, capitalize. But here, no name is given — just “The Mayor”. In general, if it’s referring to a specific mayor (like “the mayor of our town”), sometimes it’s lowercase. BUT in school worksheets like this, they usually want you to capitalize titles even without a name if it’s clear it’s a specific person. Let’s check the rule again: “Titles are capitalized if they are part of someone’s name.” Since no name is attached, maybe it should be lowercase? Hmm… actually, in many style guides, “mayor” is lowercase unless it’s directly before a name (e.g., “Mayor Smith”). Here, it’s “The Mayor” — which might imply a specific person, but strictly by the worksheet’s rule, since it’s not part of a name, maybe lowercase? Wait — let’s look at other examples. Sentence 6 says “The President of our student council” — that’s probably meant to be lowercase too? Actually, let’s think differently.

Looking at sentence 6: “The President of our student council...” — that’s likely meant to be lowercase because it’s not a formal title with a name. Same here: “The mayor” — unless it’s “Mayor Johnson”, it’s lowercase.

BUT — in many elementary worksheets, they treat “Mayor” as always capitalized when referring to the officeholder. To be safe, let’s follow common textbook practice: if it’s clearly referring to a specific person holding the office, capitalize. However, the rule says “if they are part of someone’s name”. Since no name is given, perhaps lowercase.

Wait — let’s compare to sentence 1: “senator O’Brien” → we capitalized because it’s part of the name. Here, no name → so “mayor” should be lowercase.

Also, “Language arts” → not a language → should be lowercase: “language arts”

✔ Fixed: The mayor visited my language arts class last week.

*(Note: Some teachers may accept “Mayor” capitalized here, but per strict rule given — only if part of name — so lowercase is safer.)*

5. My brother asked for a playstation and a pair of adidas shoes.

→ “playstation” → brand → capitalize: “PlayStation”

→ “adidas” → brand → capitalize: “Adidas”

✔ Fixed: My brother asked for a PlayStation and a pair of Adidas shoes.

---

6. The President of our student council does well in Science class.

→ “President” → not part of a name → should be lowercase: “president”

→ “Science class” → not a language → lowercase: “science class”

✔ Fixed: The president of our student council does well in science class.

---

7. Did you want to eat a burger from McDonald’s or burger king?

→ “McDonald’s” → already correct (brand)

→ “burger king” → brand → must be capitalized: “Burger King”

✔ Fixed: Did you want to eat a burger from McDonald’s or Burger King?

---

8. Our mayor gives potato chips and reese’s cups to kids for Halloween.

→ “mayor” → again, not part of a name → lowercase (same as #4)

→ “reese’s” → brand → must be capitalized: “Reese’s”

✔ Fixed: Our mayor gives potato chips and Reese’s cups to kids for Halloween.

---
