"Me and him went to the store and we buyed chips and then we seen a dog it was really cute and we wanted to keep it."
Any upper elementary teacher can read that sentence and count the errors without trying: a pronoun problem, two irregular verbs, a run-on, and a missing comma or two. The student who wrote it is not careless. They are writing the way they talk, and nobody has yet shown them, clearly and repeatedly, how written English works differently.
This guide starts where real grammar teaching usually starts: with the mistakes. Below are the errors that show up most often in grades 4–6 writing, why students make them, and specific ways to teach them away. After that you will find a mini-lesson structure that moves from rule to writing, a four-week pacing plan, ideas for differentiation, and suggestions for making grammar carry over into students' own work.
Start With What Students Actually Write
Before you plan a grammar sequence, collect a stack of recent student writing and skim it with one question in mind: what errors show up again and again? You will probably find that a handful of patterns account for most of the problems. That list becomes your priority list.
A short pre-test helps too. A mixed review of sixteen or so questions that touch several skills can show where a class is solid and where it is shaky, and repeating it later shows growth. The Parts of Speech Grammar Workbook includes a 16-question mixed grammar review designed to be used as both a pre and post test.
The Mistakes, One by One
1. Sentence fragments
What it looks like: "Because it was raining." "When we got to the park."
Why it happens: Students often write a dependent clause and stop, especially when answering a question. In speech, "Because it was raining" is a complete answer. In writing, it needs an independent clause.
How to fix it: Teach the difference between independent and dependent clauses directly. Give students a stack of clause strips and have them sort them into "can stand alone" and "needs help." Then have them pair each dependent clause with an independent one. Teach the test: "If someone walked into the room and heard only this, would it make sense?"
2. Run-on sentences
What it looks like: "We went to the beach it was hot."
Why it happens: Students know where their ideas end but do not yet see sentence boundaries in writing. Comma splices ("We went to the beach, it was hot") are a common variation.
How to fix it: Teach three repairs: a period, a comma plus a coordinating conjunction, or a subordinating conjunction. Have students fix the same run-on all three ways and read each version aloud. Hearing the difference helps them choose.
3. Subject–verb agreement
What it looks like: "The list of names are long." "My brother and sister was home."
Why it happens: Students match the verb to the closest noun instead of the true subject, or forget that compound subjects are plural.
How to fix it: Have students cross out prepositional phrases first, then find the subject. In "The list of names is long," cover up of names and the subject, list, is left with its verb. This connects agreement to prepositions, which makes both skills stick.
4. Irregular past tense
What it looks like: "buyed," "brang," "seen" used as a past tense verb, "had went."
Why it happens: Students apply the regular -ed rule, or use forms they hear at home or in their community. It is important to treat this as learning the conventions of written standard English, not as correcting how a family speaks.
How to fix it: Keep a class chart of common irregular verbs with present, past and past participle forms. Practice them orally in short chants or games, then in writing. Focus on the ones you see most in student work.
5. Shifting verb tense
What it looks like: "We walk to the park and then we played tag."
Why it happens: Students lose track of the time frame in longer pieces.
How to fix it: Teach the progressive tenses and helping verbs alongside simple tense so students have the full set of tools. Then have them highlight every verb in one paragraph of their own writing and check that they all match the time frame.
6. Pronoun case
What it looks like: "Me and him went." "She gave it to Sam and I."
Why it happens: Compound subjects and objects make it hard to hear the right form.
How to fix it: Teach the "take one out" trick. "Me went" sounds wrong, so it should be "He and I went." "She gave it to I" sounds wrong, so it should be "to Sam and me." Pair this with direct teaching of subject and object pronouns.
7. Adjective or adverb?
What it looks like: "She ran quick." "He did good on the test."
Why it happens: Informal speech often uses adjectives where adverbs belong.
How to fix it: Teach the question test: adjectives tell which one, what kind or how many about a noun; adverbs tell how, when, where or how much about a verb. Have students draw an arrow from the describing word to the word it describes. If the arrow points to a verb, it needs to be an adverb.
8. Commas everywhere, or nowhere
What it looks like: Commas between every phrase, or long lists with no commas at all.
Why it happens: Many students learned "put a comma where you pause," which leads to random commas.
How to fix it: Teach specific comma rules one at a time: commas in a series first, then after introductory words and phrases, then before a coordinating conjunction in a compound sentence, then in direct address and dates. Make the rule visible each time: "Which rule is this comma following?"
9. Apostrophes for plurals
What it looks like: "I have two cat's." "The Smith's are coming."
Why it happens: Students see apostrophes near the letter s and assume they go together.
How to fix it: Teach plural nouns and possessive nouns side by side and practice sorting them. Ask: "Does something belong to this noun?" If not, no apostrophe.
10. Commonly confused words
What it looks like: their/there/they're, your/you're, its/it's, to/too/two.
Why it happens: These words sound the same, and spell checkers miss them.
How to fix it: Teach one pair or set at a time with a memory hook. "It's" can always be replaced with "it is"; if that does not make sense, use "its." Then have students hunt for that one word in their own drafts.
Why Isolated Practice Still Has a Place
Some teachers worry that grammar worksheets do not transfer to writing. It is true that practice in isolation is not enough on its own. Students need to apply grammar in their own sentences. But focused practice on one skill at a time has a real role: it lets students see a rule clearly, practice it without the distraction of composing, and build the confidence to use it in writing.
The key is to treat a worksheet as one step in a sequence, not as the whole lesson. Teach the rule, practice it in focused sentences, then apply it immediately in students' own writing.
A Mini-Lesson That Moves From Rule to Writing
Here is a structure that fits in about 20–25 minutes and works for nearly any grammar skill.
- Show the rule (3 minutes). Display the rule and two or three examples. Keep it short. Read the examples aloud and point out the key feature.
- Find it in real text (3 minutes). Show a sentence or two from a book the class is reading that uses the skill. Students notice the rule working in real writing.
- Guided practice (7 minutes). Students complete a few identify, match, circle or sort items, with you checking the first few together.
- Harder practice (5 minutes). Students edit sentences or write their own using the rule.
- Apply it (5 minutes). Students open a current piece of writing and find one place to use or fix the skill.
Each worksheet in the Parts of Speech Grammar Workbook follows a similar flow: a rule box with examples at the top, then two levels of practice. Level 1 is guided, with identifying, matching, circling, underlining and sorting. Level 2 moves into harder sentence practice, editing and writing.
Sample teacher language
For a coordinating conjunctions lesson: "Remember FANBOYS: for, and, nor, but, or, yet, so. When we join two complete sentences, we use a comma and one of these words. Watch: I wanted to go outside. It was raining. becomes I wanted to go outside, but it was raining. Which FANBOYS word did I use? Why but and not and?"
A Four-Week Pacing Plan
If you have a dedicated grammar block of 20 minutes a day, four weeks gives you time for a focused cycle. You will not cover every skill in four weeks; instead, pick the ones your pre-test and writing samples flagged.
Week 1: Nouns, verbs and agreement
- Day 1: Pre-test and reference chart review of the eight parts of speech
- Day 2: Common, proper, plural and possessive nouns
- Day 3: Action, linking and helping verbs
- Day 4: Verb tenses and irregular past tense
- Day 5: Subject–verb agreement
Week 2: Describing words and pronouns
- Day 1: Adjectives and comparing with adjectives
- Day 2: Order of adjectives
- Day 3: Adverbs, and adjective or adverb?
- Day 4: Subject and object pronouns
- Day 5: Possessive and relative pronouns
Week 3: Connecting words and sentences
- Day 1: Prepositions
- Day 2: Coordinating conjunctions
- Day 3: Subordinating conjunctions and dependent clauses
- Day 4: Simple, compound and complex sentences
- Day 5: Fragments and run-ons
Week 4: Mechanics and review
- Day 1: Capital letters, end marks and sentence types
- Day 2: Commas in a series and other comma rules
- Day 3: Apostrophes and quotation marks
- Day 4: Commonly confused words and abbreviations
- Day 5: Parts of speech review and post-test
The workbook comes with its own four-week lesson plan and teacher notes, so you can compare your priorities with that plan and adjust. Skills you do not reach can become homework, center work or spiral review later in the year.
Matching Practice to the Student
Grammar classes in grades 4–6 often include students still unsure what a noun is alongside students ready for relative pronouns. Two levels of practice on the same skill help.
Students who need support
- Start with Level 1 practice: identifying, matching and sorting before writing.
- Use color coding: nouns in one color, verbs in another.
- Keep a parts of speech reference chart on the desk.
- Read sentences aloud together; many errors become easier to hear than to see.
- Reduce the number of items and focus on accuracy.
Students ready for more
- Move to Level 2 practice: editing and writing original sentences.
- Ask them to write a short paragraph that uses a skill several times correctly.
- Have them find examples in published texts and explain the rule.
- Let them design their own editing challenge for a partner.
English learners
Grammar rules that native speakers absorb through listening often need explicit teaching for English learners. Word order of adjectives, irregular verbs, articles and prepositions can be especially tricky. Give extra oral practice and visual examples, and value growth over perfection.
Students with learning differences
For students with writing or attention challenges, chunk worksheets into smaller pieces, provide answer frames, and allow oral responses where possible. Focus on one or two high-impact skills, such as complete sentences and capital letters, rather than many at once.
Making Grammar Stick in Writing
The goal of all grammar teaching is better writing. These habits help close the gap.
- The one-skill edit. After each lesson, students reread a recent draft looking for only that skill. One focus is much more manageable than "check your grammar."
- Grammar spotlights. When a student uses a skill well, read their sentence aloud. Real models from classmates are powerful.
- Editing checklists that grow. Add each new skill to a class editing checklist as it is taught.
- Sentence combining. Give students two or three short sentences and ask them to combine them using conjunctions, clauses or commas.
- Spiral review. Revisit earlier skills in warm-ups and homework throughout the year.
A quick example of a one-skill edit
Say the class just practiced subordinating conjunctions. A student's draft reads: "I was nervous. The game started. My team was losing." In a one-skill edit, the student looks only for places to join ideas with words like because, when, although or until. The revision becomes: "I was nervous when the game started, because my team was already losing." Nothing else in the draft needs to change today. The student has used the new skill in real writing, and you can see it on the page.
Running Grammar Without the Groans
- Keep lessons short. Twenty minutes of focused grammar beats an hour of drill.
- Self-checking. Let students check their own Level 1 work against an answer key so you can spend your time on Level 2 conversations.
- Partner editing. Pairs edit one sentence together and explain their choice to another pair.
- Centers. A grammar center with one skill per week fits easily into literacy rotations.
- Celebrate fixes. When students correct their own errors in writing, notice it out loud.
Grammar at Home
Families do not need to know grammar terms to help.
- Ask children to read their writing aloud before turning it in. Many errors become audible.
- Play quick games: "Name three adjectives for your shoes."
- Point out apostrophes and commas on signs and menus.
- Notice homophones together: "Is that their, there or they're?"
- Keep homework short and focused on one skill.
Frequently Asked Questions
What grammar should 4th, 5th and 6th graders know?
By the end of upper elementary, students typically work with all eight parts of speech, verb tenses, pronouns, conjunctions, clauses, sentence types, and core punctuation rules such as commas, apostrophes and quotation marks. The exact expectations depend on your curriculum.
Should I teach grammar in isolation or within writing?
Both. Short focused lessons help students understand a rule, and immediate application in their own writing makes it stick. Teach the rule, practice it, then use it in a draft the same day.
How do I know which skills to teach first?
Look at student writing and give a short pre-test. Focus first on the errors that appear most often and that affect meaning, such as fragments, run-ons, verb tense and agreement.
How long should a grammar lesson be?
About 20 to 25 minutes works well for most upper elementary classes: a brief rule, guided practice, harder practice and a quick application.
Can I use grammar worksheets for homework?
Yes, especially for skills already taught in class. Keep homework to one skill and a short set of items so students can practice independently.
How do I measure progress?
Give the same mixed review at the start and end of a unit, and look for the target skills in students' writing over time. Improvement in their own writing is the most meaningful measure.
