Edit capital letters in titles, commas in addresses, dialogue punctuation and possessive nouns, and spell with patterns, word parts and a dictionary

Learning goal: This lesson teaches Ohio's 2026 standard L.3.2, first implemented in 2027-28: know and apply the conventions of formal American English capitalization, punctuation and spelling when writing. You will capitalize appropriate words in titles; use commas in addresses; use commas and quotation marks in dialogue; form and use possessive nouns; and spell words accurately using grade-level spelling patterns (phonics) and meaningful word parts (morphology), consulting print and digital resources as needed.

Original draft to edit — A Trip to the Library. Read this third grader's draft (a fictional student). It has one or more mistakes for each rule in this lesson.

> last Saturday my brother and I walked to the libary at 220 Maple Street Columbus Ohio with our mom. I found a book called the secret of the old mill. thank you I said to the librarian. can I keep it for two weeks I asked. My brothers backpack was already full, so we put both books in the librarians book bag. We stoped at the park on the way home. I was hopeing to read the whole book before dinner.

a. Capital letters in titles. In a title, capitalize the first word, the last word and every important word: nouns, pronouns such as my and who, verbs, adjectives such as old, and adverbs. Short words such as a, an, the, and, but, or, of, in, on, at, to and for stay lowercase unless they are the first or last word. So the secret of the old mill becomes The Secret of the Old Mill: The is first, Secret, Old and Mill are important, and of and the in the middle stay small. Different books and teachers sometimes follow slightly different title styles; use the style your class uses, and use it the same way every time.

b. Commas in addresses. When an address is written inside a sentence, put a comma between the street and the city and between the city and the state: 220 Maple Street, Columbus, Ohio. If the sentence keeps going after the state, put a comma after the state too: We walked to 220 Maple Street, Columbus, Ohio, with our mom. On an envelope, the address goes on separate lines, and the comma goes between the city and the state (Columbus, Ohio); the ZIP code follows the state with no comma. (The address in the draft is invented for practice.)

c. Commas and quotation marks in dialogue. Quotation marks go around a speaker's exact words. The first word of the spoken sentence gets a capital letter. When the speaker tag comes after the words, end the spoken part with a comma inside the closing quotation mark: "Thank you," I said. If the spoken words are a question or an exclamation, use a question mark or exclamation point instead of the comma, still inside the quotation marks: "Can I keep it for two weeks?" I asked. When the tag comes first, put a comma after it: I asked, "Can I keep it for two weeks?" Start a new paragraph each time a different person speaks.

d. Possessive nouns. A possessive noun shows that something belongs to someone. For one owner, add an apostrophe and s: my brother's backpack (one brother), the librarian's book bag (one librarian). For more than one owner when the plural already ends in s, add only an apostrophe after the s: the two girls' coats. For a plural that does not end in s, add an apostrophe and s: the children's room. A plain plural that owns nothing gets no apostrophe: three books, not three book's.

e. Spelling with patterns, word parts and resources. Good spellers use three tools.

Phonics patterns. Clap a long word into syllables and spell each syllable by its sound and syllable type: li-brar-y has an open syllable (li), a vowel-r syllable (brar) and a final y. Saying it carefully, with every sound in every syllable, fixes libary, which leaves out the first r. Some sounds have spellings that depend on their place in a word. When the long a sound is spelled with two vowel letters together (a vowel team), the team is usually ai in the middle of a word (rain, train) and ay at the end (play, stay). Long a in the middle of a word is also very often spelled a-consonant-e (cake, gate), so check a dictionary when you are not sure which spelling a word uses. The oi sound is usually oi in the middle (coin, point) and oy at the end (boy, enjoy). Word families share a pattern: night, light, bright all use igh.

Word parts. Spell the base word first, then add the prefix or suffix and apply the rule. A prefix does not change the base (un + tie = untie). Suffix rules: double the final consonant of a one-syllable, short-vowel word ending in one consonant (not x, w or y) before a vowel suffix (stop → stopped); usually drop a silent e before a vowel suffix (hope → hoping); change a consonant + y to i before most suffixes (happy → happiness), but keep the y before -ing (carry → carrying).

Resources. When a word still looks wrong, check it in a print dictionary (use the guide words at the top of each page and alphabetical order to find the page) or a digital dictionary. A spell checker helps, but it can accept a real word that is the wrong word (there or their for they're, which means they are) or suggest the wrong fix, so read each suggestion and choose the word that fits your sentence.

Worked example a — a title. a trip to the zoo → A Trip to the Zoo. A is capitalized because it is the first word; Trip and Zoo are important words; to and the are short words in the middle, so they stay lowercase.

Worked example b — an address in a sentence. Draft: We mailed a card to 45 Oak Road Dayton Ohio on Monday. Edited: We mailed a card to 45 Oak Road, Dayton, Ohio, on Monday. Commas go between the street and the city, between the city and the state, and after the state because the sentence keeps going.

Worked example c — dialogue. Draft: thank you I said to the librarian. can I keep it for two weeks I asked. Edited: "Thank you," I said to the librarian. The spoken words get quotation marks, a capital T and a comma inside the closing mark. Then: "Can I keep it for two weeks?" I asked. The question mark replaces the comma because the spoken words ask a question. With the tag first: I asked, "Can I keep it for two weeks?" A comma follows the tag, and the question mark stays inside the quotation marks.

Worked example d — possessives. Draft: My brothers backpack … the librarians book bag. The writer has one brother and one librarian, so each is a singular owner: my brother's backpack, the librarian's book bag. If the writer had two brothers who shared a backpack, it would be my brothers' backpack.

Worked example e — spelling with all three tools. libary: say it carefully, li-brar-y; the middle syllable begins with the blend br, and the draft left out that r, so the spelling is library. stoped: stop has one syllable, one short vowel and one final consonant, and -ed begins with a vowel, so double the p: stopped. hopeing: hope ends in silent e and -ing begins with a vowel, so drop the e: hoping. The writer checks library in a print dictionary between the guide words and confirms it.

The edited draft. Last Saturday my brother and I walked to the library at 220 Maple Street, Columbus, Ohio, with our mom. I found a book called The Secret of the Old Mill. "Thank you," I said to the librarian. "Can I keep it for two weeks?" I asked. My brother's backpack was already full, so we put both books in the librarian's book bag. We stopped at the park on the way home. I was hoping to read the whole book before dinner.

Editing checklist (record task): Make a five-row checklist: titles, addresses, dialogue, possessives, spelling. Edit a new draft your teacher gives you. For each change, write the row it belongs to and the rule you used.

Spelling detective: Choose five words you misspelled in your own writing this month. For each one, write the correct spelling and the tool that fixes it: syllable by syllable, a position pattern (ai/ay, oi/oy), a suffix rule, or a dictionary check. Look up at least one word in a print dictionary and one in a digital dictionary.

Independent performance: Write a short story or letter (at least eight sentences) that includes the title of a book or show, an address written inside a sentence, at least two lines of dialogue, one singular and one plural possessive noun, and at least four words with suffixes. Then edit it. Success criteria: (1) title words are capitalized by the rule; (2) the address has commas in the right places; (3) dialogue has quotation marks, a capital at the start of the spoken words and the correct comma or end mark inside the closing mark; (4) each possessive noun has its apostrophe in the right place, and plurals that own nothing have none; (5) words are spelled correctly using patterns and word parts, and you checked at least one word in a print or digital dictionary.
