Apply formal American English grammar and usage in writing and speaking

Learning goal: This lesson teaches Ohio's 2026 standard L.3.1, first implemented in 2027-28: know and apply formal American English grammar, usage and mechanics when writing or speaking. You will explain the function of nouns, pronouns, verbs, adjectives and adverbs in general and in particular sentences; form and use regular and irregular plural nouns; use abstract nouns; form and use regular and irregular verbs; form and use the simple verb tenses; ensure subject-verb and pronoun-antecedent agreement; form and use comparative and superlative adjectives and adverbs and choose between them depending on what is modified; use coordinating and subordinating conjunctions; and produce simple, compound and complex sentences. This lesson brings together skills from the earlier third-grade grammar lessons and asks you to apply all of them at once in a real piece of formal writing and a short formal talk.

Grammar, usage and mechanics. Grammar is how words work together in sentences. Usage is choosing the accepted form, such as brought instead of brang. Mechanics are capital letters and punctuation. Formal American English is the version used in school reports, presentations and letters to people we do not know well. In a chat with a friend, "Me and Jo was swimming" might be understood, but in formal writing and speaking we say "Jo and I were swimming."

Five parts of speech and their functions. In general, a noun names a person, place, thing or idea; a pronoun takes the place of a noun; a verb shows action or being; an adjective describes a noun or pronoun; an adverb describes a verb, an adjective or another adverb, often telling how, when or where. But a word's function in a particular sentence is what counts. Swim is a verb in "We swim on Saturdays" but a noun in "The swim was cold." Fast is an adjective in "a fast swimmer" and an adverb in "She swam fast."

Plural nouns. Regular plurals add -s or -es: duck → ducks, bench → benches. Irregular plurals change in other ways: woman → women, child → children, tooth → teeth, mouse → mice, sheep → sheep. Never add -s to an irregular plural (childrens is not a word).

Abstract nouns. An abstract noun names an idea, feeling or quality you cannot touch: childhood, courage, friendship, fear, honesty. It is still a noun because it names something and can be a subject: "Her courage surprised everyone."

Regular and irregular verbs. Regular verbs add -ed for the past: play/playing/played. Irregular verbs change differently: swim/swimming/swam, go/going/went, bring/bringing/brought, run/running/ran. Notice that the -ing form of swim doubles the m (swimming) because swim has one syllable, one short vowel and one final consonant, and -ing begins with a vowel.

Simple verb tenses. Past: I walked. Present: I walk. Future: I will walk. Keep the tense consistent within a paragraph unless the time really changes.

Agreement. A verb must agree with its subject. A singular subject such as the girl, he or she takes swims; a plural subject such as the girls or they takes swim; and I and you also take swim (I swim, you swim). A pronoun must agree with its antecedent, the noun it refers back to: "The girls packed their towels" (plural antecedent, plural pronoun), "Mateo packed his towel" (singular antecedent, singular pronoun).

Comparatives and superlatives. Use the comparative (-er or more) to compare two and the superlative (-est or most) to compare three or more. Choose an adjective when the word modifies a noun (the faster swimmer, the most careful diver). Choose an adverb when it modifies a verb (she swam faster, he dove most carefully). Short words usually add -er/-est; many longer words and most -ly adverbs use more/most: carefully → more carefully → most carefully. Some forms are irregular: good/better/best, well/better/best, bad/worse/worst. Never double up: more faster is incorrect.

Conjunctions. Coordinating conjunctions join equal parts: for, and, nor, but, or, yet, so. Subordinating conjunctions begin a dependent clause that cannot stand alone: although, because, since, when, if, after, before, while. A clause has its own subject and verb, so after the race ended is a dependent clause. In after lunch no subject and verb follow, so after is not working as a conjunction there; the same is true of before and since.

Simple, compound and complex sentences. A simple sentence has one independent clause: "Nora swam." A compound sentence has two independent clauses joined together; in third grade you join them with a comma and a coordinating conjunction: "Nora swam, but Leo waded." A complex sentence has an independent clause and a dependent clause: "Because the water was cold, Leo waded."

Misconception: "If it sounds fine when I talk, it is correct in formal writing." Everyday speech follows its own patterns, and many are fine among friends. Formal English has agreed rules for school and public situations. "Them boys brang their towels" may sound normal to some speakers, but the formal version is "Those boys brought their towels."

Worked model inside the lesson. Read this original draft, then the edited version.

Original draft — The Swim Meet. "Last saturday me and my sister goes to the swim meet. The mans at the gate checked our tickets. My sister swimmed the most fastest of the three girls in her race, and I was proud. The swimmers dried themself with towels. The crowd cheered loud. We was tired we were happy."

Edited, formal version. "Last Saturday, my sister and I went to the swim meet. The men at the gate checked our tickets. My sister swam the fastest of the three girls in her race, and pride filled my chest. The swimmers dried themselves with towels. The crowd cheered loudly. Although we were tired, we were happy."

Changes: capital S for the day name (mechanics); my sister and I as a formal subject and went for past tense agreement; irregular plural men; irregular past swam and superlative adverb fastest for three racers, with no doubled most; the abstract noun pride; pronoun themselves agreeing with the plural antecedent swimmers; adverb loudly because it modifies the verb cheered; we were so the verb agrees with we; and a complex sentence with although fixing the run-on. The paragraph now has simple, compound and complex sentences.

Worked function in a particular sentence: "The tired swimmer quickly grabbed her towel." Swimmer and towel are nouns (they name a person and a thing); her is a pronoun (it stands for the swimmer); grabbed is a verb (action); tired is an adjective (it describes the noun swimmer); quickly is an adverb (it tells how she grabbed). Each label comes from the word's job here.

Worked adjective or adverb comparison: Fill the blanks for two swimmers, Ana and Raj: "Ana is a ___ swimmer than Raj (fast). Ana swims ___ than Raj (careful)." First blank modifies the noun swimmer, so use the comparative adjective faster. Second blank modifies the verb swims; careful becomes the adverb carefully, and its comparative is more carefully. Two people are compared, so both are comparatives, not superlatives.

Worked agreement: Draft: "The twins packs her goggles. Mateo pack his towel." Find each subject and antecedent. The twins is plural, so the verb becomes pack and the pronoun referring back to the twins becomes their: "The twins pack their goggles." Mateo is one person, so the verb becomes packs, and his already agrees with the singular antecedent: "Mateo packs his towel." Check both kinds of agreement in every sentence that has them: subject with verb, and pronoun with antecedent.

Worked sentence types with conjunctions: Ideas: "The pool opened. It was raining." Simple: "The pool opened." Compound with a coordinating conjunction: "The pool opened, yet it was raining." Complex with a subordinating conjunction: "Although it was raining, the pool opened." Yet and although both show contrast; so would be wrong here: "The pool opened, so it was raining" would say that opening the pool caused the rain, which makes no sense.

Record: grammar editing chart. Make a chart with rows for each skill: parts of speech, plurals, abstract nouns, verb forms, tenses, subject-verb agreement, pronoun-antecedent agreement, comparatives and superlatives, conjunctions, sentence types. Edit a new draft your adult gives you, and for each change write the row it belongs to and why you made it.

Speaking practice: Give a one-minute formal report about something you did last weekend. A partner listens for agreement, past-tense verbs and at least one compound and one complex sentence, and tallies them.

Independent performance: Write a formal paragraph of at least eight sentences about a sports event, a performance or a trip, then read it aloud as a short formal report. Success criteria: (1) you label the function of one noun, pronoun, verb, adjective and adverb in one of your own sentences; (2) you use at least one regular and one irregular plural, and one abstract noun; (3) you use at least one irregular past-tense verb correctly; (4) the tense stays consistent; (5) every subject and verb agree and every pronoun matches its antecedent; (6) you use one comparative and one superlative, and at least one of them is an adverb; (7) you use at least one coordinating and one subordinating conjunction; (8) your paragraph has at least one simple, one compound and one complex sentence.
