Write complete sentences with clear pronouns, precise verb tenses and correct connecting words

Learning goal: This lesson teaches Ohio's 2026 standards L.5.1 and WF.5.3, first implemented in 2027-28. You will know and apply formal American English grammar, usage and mechanics when writing or speaking, and write in complete sentences to demonstrate knowledge of conventions. That means: define conjunction, preposition and interjection and explain their function in particular sentences; form and use the perfect verb tenses; use verb tense to convey various times, sequences, states and conditions; use consistent verb tenses within and across sentences and recognize shifts in verb tense; use correlative conjunctions; and use varied pronouns and their antecedents correctly in composing and revising writing.

Complete sentences. A complete sentence has a subject (who or what the sentence is about), a predicate (what the subject does or is) and expresses a complete thought. "The river flooded the road." A fragment is missing one of these: "Because the river flooded." has a subject and verb but is not a complete thought, because because makes the reader wait for the rest. Fix: "Because the river flooded, the road closed." A run-on joins two complete sentences without correct punctuation or a connecting word: "The river flooded the road it closed for a week." Fix with a period, a comma plus a conjunction ("..., and it closed") or a subordinating conjunction.

Conjunctions, prepositions and interjections. A conjunction joins words, phrases or clauses and shows how they relate: and adds, but contrasts, so shows a result, because gives a reason. A preposition begins a phrase that connects a noun or pronoun to the rest of the sentence, often showing place or time: under the bridge, after lunch, across the field. An interjection expresses feeling and is set apart from the sentence: Wow! Oh, Hey,. The same word can play different roles: in "We ate after the game," after is a preposition beginning a phrase; in "We ate after the game ended," after is a conjunction joining a clause. Name the part of speech by what it does in that sentence.

Correlative conjunctions come in pairs: either/or, neither/nor, both/and, not only/but also, whether/or. Keep the words after each part parallel: "She will either walk or ride" (two verbs), not "She will either walk or on the bus." When either/or or neither/nor joins two subjects, the verb agrees with the nearer subject: "Neither the students nor the teacher was late"; "Neither the teacher nor the students were late." Both/and works differently: it joins two subjects into a plural one, so the verb is plural: "Both Theo and his brother were ready."

Verb tenses convey time, sequence, states and conditions. Simple tenses place an action in time: "Matt completed the task" (past); "Matt completes the task" (present); "Matt will complete the task" (future). The perfect tenses use a form of have plus the past participle. The past participle is the verb form used after have: for regular verbs it ends in -ed, the same as the past tense (complete, completed, has completed); irregular verbs have their own form (write, wrote, has written; go, went, has gone). The perfect tenses connect an action or state to a later reference time: often an action finished before that time, and sometimes a state that has lasted up to it. Present perfect: "Matt has completed the task" (finished before now, and it matters now). Past perfect: "Matt had completed the task before lunch" (finished before another past time). Future perfect: "Matt will have completed the task by the end of the day" (will be finished before a future time). Tense can also show a state, a condition that lasts: "The bridge has been closed since June" uses the present perfect for a state that began in June and is still true now. And tense helps show conditions: "If it rains tomorrow, the game will be canceled."

Consistent tense and shifts. Within a sentence and across a paragraph, keep the same tense unless the time, the order of events or a condition really calls for a change (an if condition about the future uses the present: "If it rains, we will stay in"). Ohio's example: "Yesterday she walked to the playground, talks to her friends, and played basketball" shifts wrongly from past to present with talks; it should be talked. A shift is correct when the time actually changes: "I finished the book yesterday, and now I am reading its sequel."

Pronouns and antecedents. A pronoun takes the place of a noun. Its antecedent is the noun it refers to. In "Lena lost her scarf, but she found it later," her and she refer to Lena, and it refers to the scarf. Pronouns such as he, she, it, they, him, her, them and their must agree with their antecedents in number (one or more than one) and must point to one clear antecedent. Ohio's examples are "Eddie played his guitar; Sarah and Megan played their instruments." His agrees with one person, Eddie; their agrees with two people, Sarah and Megan. A pronoun for one person also matches that person (he, his for Eddie; she, her for Sarah), which means the pronouns that person uses. They and their can also refer correctly to one person: a person who uses they, or someone you do not know or do not need to name ("Someone left their hat on the bus"). So a pronoun is wrong when it does not fit the antecedent the writer means and what the writing tells the reader about it, or when it could point to more than one noun. I, me, we, us and you usually need no written antecedent, because they point to the writer, the speakers or the reader. Use varied pronouns so writing does not repeat nouns: subject pronouns (I, you, he, she, it, we, they), object pronouns (me, him, her, us, them), possessive pronouns (my, his, her, its, our, their) and reflexive pronouns (myself, himself, themselves). Watch for unclear reference: "Maria told Jen that she won the race" leaves the reader asking who won. Fix: "Maria told Jen, 'You won the race.'" When you revise your writing, circle each pronoun such as he, she, it, they, his, her or their, and draw an arrow to its antecedent. If the arrow could go to two nouns, or if the pronoun and its antecedent do not agree, change the pronoun or repeat the noun. Subject-verb agreement, and more practice in revising verb tenses, tense shifts, perfect tenses and correlative conjunctions, are in the companion lesson on revising for subject-verb agreement, verb tenses and correlative conjunctions.

Original paragraph for editing — The Canal Boat Trip

Last summer my brother, my cousins (Theo and the twins) and I ride a canal boat on the old canal near my aunt's town. Because the mules pulled the boat. It moved slowly. My cousin Theo and my brother argued about who would steer, he wanted the first turn. Neither Theo nor the twins was allowed to steer, the guide explained that only trained crew handle the tiller. By the time we reached the lock, the guide has told us three stories about the canal. Wow the water level in the lock rose while we watch. Both my brother and me agreed it was the best part.

(The paragraph is a practice text. It describes a fictional family trip; it does not report facts about any particular boat ride.)

Worked model inside the lesson — editing the first three sentences. Sentence 1: "ride" shifts to present in a paragraph about last summer; change to rode. Sentence 2 is a fragment: "Because the mules pulled the boat." (This lesson numbers the fragment and the short sentence after it, "It moved slowly," together as sentence 2, because they are one thought, so the paragraph has seven numbered sentences.) Join them: "Because the mules pulled the boat, it moved slowly." Sentence 3 has two problems: it is a run-on, and he has two possible antecedents (Theo or my brother). Fix: "My cousin Theo and my brother argued about who would steer. Theo wanted the first turn."

Worked example 1 — Finishing the edit. Sentence 4: with neither...nor, the verb agrees with the nearer subject, the twins, so was becomes were; the sentence is also a run-on, so split it: "Neither Theo nor the twins were allowed to steer. The guide explained that only trained crew handle the tiller." (Handle stays present because it states a rule that is still true.) Sentence 5: the story is in the past and the telling happened before reaching the lock, so use past perfect: "By the time we reached the lock, the guide had told us three stories." Sentence 6: set off the interjection and fix the shift: "Wow! The water level in the lock rose while we watched." Sentence 7: me is an object pronoun used as a subject; write "Both my brother and I agreed."

Worked example 2 — Choosing a tense for meaning. Which sentence shows the task is finished before a future deadline? (a) "Kai will finish the model." (b) "Kai will have finished the model by Friday." Sentence (b), future perfect, because will have finished shows completion before the future time Friday. Sentence (a) only places the action in the future.

Worked example 3 — Explaining functions in one sentence. "Oh, we waited under the bridge until the rain stopped, and then we ran." Oh is an interjection expressing mild surprise or feeling. Under is a preposition beginning the phrase under the bridge, which tells where. Until is a conjunction joining the clause the rain stopped, telling when. And is a conjunction joining two complete clauses in time order.

Worked example 4 — Revising pronouns and antecedents. A draft about the same trip says, "The twins forgot her tickets, and Theo left their hat on the boat." The writer means that the tickets belong to the twins and the hat belongs to Theo, who uses he and him. Circle each pronoun and find its antecedent. Her is meant to refer to the twins, two people, so it must be plural: their tickets. Their is meant to refer to Theo. Singular their can be correct for one person, but Theo uses he, so the matching pronoun is his hat. Revised: "The twins forgot their tickets, and Theo left his hat on the boat." Now each pronoun agrees with its antecedent, as in Ohio's examples: one person, his; two people, their.

Representation task — grammar tool chart. Make a chart with five rows: complete sentence, conjunction/preposition/interjection, perfect tenses, tense consistency, pronoun and antecedent. In each row write a one-sentence rule in your own words, one correct example of your own and one incorrect example with its correction.

Independent performance. Write a paragraph of eight to ten sentences in the past tense about a trip, event or project. Include: one sentence with a correlative conjunction; one sentence in past perfect and one in future perfect (for example, a plan for next time); one interjection; at least two prepositional phrases; one condition using if; and at least four different pronouns. Then trade with a partner who circles every pronoun and draws an arrow to its antecedent, or, for I, we and you, writes who it refers to.

Success criteria: Every sentence is complete, with no fragments or run-ons. Verb tenses stay consistent except where the time, the order of events or a condition really calls for a change, and you can explain each change. The perfect tenses are formed correctly with has/have/had/will have plus the past participle. The correlative pair is parallel; with either/or or neither/nor joining two subjects the verb agrees with the nearer subject, and with both/and it is plural. Every pronoun refers clearly to one person or thing; third-person pronouns have one clear antecedent and agree with it. You can label a conjunction, a preposition and an interjection in your paragraph and explain what each does in its sentence.
