Pronoun Errors and Possessive Determiners: Mini-Lessons That Work

Pronoun errors are some of the most stubborn mistakes in elementary writing. You correct "him and I" in October and see it again in March. The reason is simple. Students choose a pronoun by who they are talking about, not by what the word does in the sentence. A short, focused mini-lesson on the role of the word works better than another round of corrections in the margin.

The errors students actually make

These are the pronoun mistakes I see most often in Grades 3–6, in both native speakers and English learners.

• Me and my friend went. An object pronoun used as a subject, usually in a pair.
• Between you and I. The reverse: a subject pronoun after a preposition, often because students have been told "me" is wrong.
• Their, they're and there. Three words that sound the same and do three different jobs.
• Its and it's. The possessive determiner with an apostrophe it should not have.
• Whose and who's. The same problem with a question word.
• She go, he like. The missing -s on the verb after he, she and it, common for English learners.
• His and her mixed up. Frequent for learners whose first language marks possessives differently.

The first two errors are really the same error. Students do not know the role test, so they swing from one wrong form to the other.

Mini-lesson: the cover test

For "me and my friend" and "him and I," cover the other person. "Me went to the park" sounds wrong to almost every student. "I went to the park" sounds right. So the pair is "My friend and I went." It works the other way too: "The teacher gave the book to I" is clearly wrong, so it is "to my friend and me."

Write three sentences on the board, have students cover the extra person with a finger and choose the pronoun. This takes five minutes, and students can use it on their own writing afterward. The Pronouns & Possessive Determiners unit builds this into its mixed-grammar and error clinic modules, where students choose each form by its role.

Mini-lesson: determiner or contraction?

For their and they're, its and it's, and whose and who's, the test is to expand the word. If you can say "they are," "it is" or "who is," use the apostrophe. If you cannot, you need the possessive determiner, which always stands before a noun. "The dog wagged it is tail" makes no sense, so it is "its tail."

I have students sort a set of sentence cards into two piles: "can expand" and "can't expand." Then they write the correct word on each card. Once they notice that possessive determiners always come before a noun (their bikes, its tail, whose coat), the choice becomes easier.

Mini-lesson: ownership and distance

For younger students and English learners, ownership is easiest to practice with real objects. Collect a few classroom items and ask "Whose pencil is this?" Students answer with a possessive determiner: "It's her pencil." Then add distance with this and that. "This pencil is my pencil. That pencil is his pencil." Holding the object close or pointing to one across the room makes the difference obvious.

For the his and her mix-up, keep the owner visible. Point to the person, then to the object, and ask whether the owner is a boy or a girl. Many learners are matching the pronoun to the object instead, and this makes the owner the focus.

How to respond in student writing

Marking every pronoun error in red rarely changes behavior. I mark the first one, name the test to use, and ask the student to find the rest. "There are two more pronoun errors in this paragraph. Use the cover test." That shifts the work to the student, where it belongs.

For the missing -s after he, she and it, a highlighter works well. Students highlight every he, she and it in a draft, then check the verb right after it. The error clinic in the unit follows the same principle: students find and fix mistakes themselves. The teacher edition gives model answers and an assessment anchor per module, which helps you judge whether a student has learned the rule or is still guessing.

Pronoun work sticks when it comes back regularly, in short bursts. Two or three sentences at the start of a lesson are enough. Daily ELA Practice task cards for Grades 3–5 fit that kind of routine. For a quick grammar review with older students, Grammar & Punctuation Practice for Grades 4 to 6 is another short option. Our page on teaching pronouns to ELA and ESL students gives an overview of the full unit.
