Grade 3 • Common & Proper Nouns • About 20 minutes
You will learn to: sort common and proper nouns • fix capitals • beat the tricky cases • try a bonus name game
Includes: 4 activities • a free printable PDF • a teacher guide • a full answer key
Curriculum: Builds on CCSS L.1.1.b (common and proper nouns) and L.2.2a (capitalizing holidays, product names, and geographic names); supports Grade 3 capitalization conventions, CCSS L.3.2.
The Golden Rule
Specific = capital letter. General = small letter.
A common noun names a general person, place, thing, or idea — teacher, city, dog. A proper noun names a specific one — Ms. Johnson, Chicago, Buddy. This free worksheet practices that one rule four ways: sort it, fix it, choose it, stretch it. Full answer key included — about 20 minutes.
First, a Quick Refresher
Ask one question about any noun: “Which one?” Any one of many → common, no capital. That one, by name → proper, always a capital. (New to nouns? Start with What Is a Noun?; the full guide is Common Noun and Proper Noun.)
| Common noun | Proper noun | |
|---|---|---|
| What it names | A general person, place, thing, or idea | One specific one, by name |
| Capital letter? | No — except at the start of a sentence | Yes — always, everywhere |
| Person | teacher | Ms. Johnson |
| Place | city | Chicago |
| Thing | dog | Buddy |
| Idea / time | holiday | Thanksgiving |
PERSON
teacher → Ms. Johnson
PLACE
city → Chicago
THING
dog → Buddy
IDEA
holiday → Thanksgiving
How to Use This Worksheet
- Print it, or work on screen. Each part works alone — Parts A and B today, the rest tomorrow.
- Say “Which one?” out loud. It settles almost every capital on this page.
- Part D is a bonus. Harder on purpose — skip it, save it, or try it together.
- Check with the answer key. Finish a whole part first, then check together.
For Teachers: Using This Worksheet in Class
Before you start (2–3 minutes)
- Write the Golden Rule on the board: Specific = capital letter. General = small letter.
- Ask “Which one?” about one pair — city / Chicago — then point to Part B, Question 1: already worked.
You need: one printed sheet per child (PDF pages 1–2) and a pencil.
Timing (about 20 minutes): teach 4 • Parts A–C 11 • check together 5. Part D runs on its own for fast finishers.
Support (for students who need a step up): keep the refresher table visible, do Part A in pairs, say “Which one?” to a partner first.
Challenge (for fast finishers): Part D — plural names and “a little Einstein,” the Grade 4–5 stretch.
Quick check before they leave: each student turns one common noun into a proper one: “river — Mississippi River.” Ten seconds each shows who owns the rule.
Homework: send pages 1–2 home; keep the key (page 3) and this guide (page 4) at school.
Part A — Sort It: Common or Proper?
Write each word from the bank in the right row and column of the grid.
Word bank: teacher • Ms. Johnson • city • Chicago • dog • Buddy • holiday • Thanksgiving • river • Mississippi River • month • July • girl • Maya • school • Lincoln Elementary School
| Common Noun | Proper Noun | |
|---|---|---|
| Person | ||
| Place | ||
| Thing | ||
| Idea / Time |
Hint: every row holds exactly two common and two proper nouns. Count as you go!
Part B — Fix the Capitals
Rewrite each sentence with the capitals fixed — some are missing, and some are there by mistake. The first one is done for you.
- (done for you) our teacher ms. johnson took us to the park. → Our teacher Ms. Johnson took us to the park.
- i love Summer because we swim every day.
- my favorite subject is Math, but my sister likes english best.
- The Teacher gave a Book to liam on monday.
- We visited the grand canyon in arizona last Spring.
- dr. patel speaks spanish and works at our School.
- In december, our class read a story about the titanic.
- My friend sara moved to texas, but she misses the mississippi river.
Hint: the classic traps — seasons and subjects stay small (languages excepted), and job words stay small until a name joins them.
Part C — Tricky Cases: You Choose
Circle the right choice in each sentence. The same word can change its answer — the sentence decides!
- “Can I have a cookie, (Mom / mom)?”
- My (Mom / mom) drives me to school.
- I walk to (school / School) every day.
- I go to (lincoln elementary school / Lincoln Elementary School).
- A (river / River) runs behind our town.
- We crossed the (mississippi river / Mississippi River) on a bridge.
- I ate an (apple / Apple) for lunch.
- My new tablet was made by (apple / Apple).
Talk it over: Questions 1 and 2 give one word two answers — mom as a name is proper; as a job word, common.
Bonus Challenge — Part D: Name Games
A stretch — teachers and older kids, jump in too! Sometimes a name does a common noun’s job: it can be plural and follow a or the — but it keeps its capital.
Finish each sentence. The name you need is in brackets.
- There are two ______ in our class. (Maya)
- The ______ live next door to us. (Patel family)
- All the ______ came to the party. (Jones family)
- The ______ moved to Texas last year. (Martinez family)
- Ben can fix any toy in the class. He is a little ______! (Einstein)
- Two ______ in the story both wanted the same name. (Emma)
The secret: names take -s like other nouns — two Mayas, the Patels. Names ending in s, x, z, ch, or sh take -es — the Joneses, the Martinezes.
Notes for Teachers and Grown-Ups
- One part at a time is fine. Parts A and B make one session; Parts C and D make another.
- Part B, Question 1 is worked. Study it first — it shows what “fixed” looks like.
- The traps are the teaching. Seasons, subjects, and job words are where Grade 3 writers lose the most capitals. Missed one? Ask “Which one?” first.
- Part C has sentence questions, not trick questions. Mom is proper in Question 1, common in Question 2 — the sentence decides.
- Part D is optional and ungraded. It previews Grades 4–5 name use; trying beats acing.
- Choosing counts more than spelling. A well-placed capital with shaky spelling is still the skill.
Wrong vs Right: 4 Mistakes Grade 3 Kids Often Make
Mistake 1 — Capitalizing seasons
❌ Wrong: “I love Summer.”
✅ Right: “I love summer.” Seasons are common — unlike days, months, and holidays.
Mistake 2 — Capitalizing school subjects
❌ Wrong: “My best Subject is Math.”
✅ Right: “My best subject is math.” Subjects stay small; languages (English, Spanish) are proper.
Mistake 3 — Dropping capitals mid-sentence
❌ Wrong: “we saw maya in chicago.”
✅ Right: “We saw Maya in Chicago.” Proper nouns keep capitals everywhere, not just at the start.
Mistake 4 — Capitalizing a job word with no name
❌ Wrong: “The Teacher called my name.”
✅ Right: “The teacher called my name.” A job word alone is common; with a name it turns proper: “Ms. Johnson called my name.”
Answer Key
Check Answers — Answer Key (for grown-ups)
Part A — Sort It
| Common Noun | Proper Noun | |
|---|---|---|
| Person | teacher, girl | Ms. Johnson, Maya |
| Place | city, school | Chicago, Lincoln Elementary School |
| Thing | dog, river | Buddy, Mississippi River |
| Idea / Time | holiday, month | Thanksgiving, July |
Sorting note: “river” is the general word, so it sits with the things; “Mississippi River” names one river — proper.
Part B — Fix the Capitals
- Our teacher Ms. Johnson took us to the park. (teacher = job word, small; Ms. Johnson proper)
- I love summer because we swim every day. (summer = season, common)
- My favorite subject is math, but my sister likes English best. (subject, math small; English = language, proper)
- The teacher gave a book to Liam on Monday. (teacher, book small; Liam, Monday proper)
- We visited the Grand Canyon in Arizona last spring. (spring = season, common)
- Dr. Patel speaks Spanish and works at our school. (school common here — no name)
- In December, our class read a story about the Titanic. (December, Titanic proper)
- My friend Sara moved to Texas, but she misses the Mississippi River. (all three names proper)
Part C — Tricky Cases
- Mom — used as her name, like Sara. Proper.
- mom — a job word here (“my mom”). Common.
- school — any school, in general. Common.
- Lincoln Elementary School — that school, by name. Proper.
- river — any river. Common.
- Mississippi River — that river, by name. Proper.
- apple — the fruit. Common.
- Apple — the company. Proper.
Bonus Challenge — Part D: Name Games
- Mayas — “two Mayas.” Names take -s for more than one person with that name.
- Patels — “the Patels” = the whole Patel family. Plain -s.
- Joneses — Jones ends in s, so it takes -es.
- Martinezes — Martinez ends in z, so it takes -es.
- Einstein — “a little Einstein” = a very smart person. The name does a common noun’s job (it follows a) but keeps its capital.
- Emmas — “two Emmas.” Plain -s, like Mayas.
Key note: plural names keep their capital. Names ending in s, x, z, ch, or sh add -es; all others add -s.

How did it feel? 😀 I did it! 🙂 Almost — one more try. 🌱 I need more practice.
My favorite proper noun today: ___
Remember: Specific Gets the Capital
Specific = capital letter. General = small letter.
- Common: teacher, city, dog, holiday
- Proper: Ms. Johnson, Chicago, Buddy, Thanksgiving
Stuck? Ask: “Which one?” One specific name → capital.
