Add Apostrophe S to Show One Owner

Ask who owns the thing, then write that owner, add 's and name the thing. If your child mixes up owners and contractions, try putting back missing letters: if it makes two words, it is a short form. Check with the answer key.

Rewrite phrases like the bone of the dog with apostrophe s to show one owner, as in the dog's bone. An apostrophe and s show that one person or thing owns something. The directions on the page read: Write each phrase again with an apostrophe and s. Then, in 9, write about your friend's pet. In 10, write about your teacher's desk. An answer key is included.

Yes, both. We made it for 2nd Grade punctuation, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with apostrophes & possession. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Students learn to add 's to a singular noun to show possession (the cat's tail) and to add just an apostrophe after the -s of a plural noun (the dogs' toys), building a foundation for more complex possessive rules later.

Both forms can end in -s, so students must distinguish between a simple plural (two dogs) and a possessive (the dog's leash), which requires understanding the difference in meaning and function.

Both contractions and possessives use apostrophes, so learning them together (or sequentially) helps students understand that apostrophes serve two distinct functions - a distinction that reduces future confusion.

Second graders build on first grade punctuation by adding commas in greetings and closings of letters, apostrophes in contractions and possessives, and more consistent use of end punctuation in longer writing. CCSS L.2.2b covers commas in letter greetings (Dear Mom,) and closings (Love, Ella), while CCSS L.2.2c introduces apostrophes in contractions (can't, I'm, don't). Students should also use commas to separate items in a series of three or more. At this stage, children move from simply placing end punctuation to understanding how punctuation affects meaning and pacing. Worksheets that require students to add missing punctuation to a passage, rather than single sentences, help build real-world editing skills. Activities that compare sentences with and without commas show students how punctuation clarifies meaning. Consistent punctuation practice in second grade creates the foundation for more complex punctuation work in third grade.

Start with contractions because they are concrete and frequently used in speech. Show your child that a contraction is two words joined together with an apostrophe taking the place of missing letters: do not becomes don't, I am becomes I'm, cannot becomes can't. Use a visual approach: write the two words, cross out the removed letters, and place the apostrophe where those letters were. Practice with the most common contractions first (don't, can't, it's, I'm, we're, they're, isn't, wasn't). Worksheets that ask students to match contractions to their expanded forms, or to rewrite sentences replacing two words with a contraction, build fluency. For possessive apostrophes, teach that adding apostrophe s shows that something belongs to someone: "the girl's book" means the book belongs to the girl. CCSS L.2.2c covers contractions specifically, making this a key second grade skill.

The most frequent punctuation errors in second grade include: forgetting commas in a series (I like apples bananas and grapes), placing apostrophes incorrectly in contractions (do'nt instead of don't or dont without any apostrophe), confusing its (possessive) with it's (contraction), and inconsistent use of end punctuation in longer writing where children get focused on their ideas and forget the mechanics. Run-on sentences also become common as children attempt more complex thoughts but do not yet know how to use commas or conjunctions to connect them properly. These errors are normal for this developmental stage. The most effective remediation is regular, short proofreading practice. Worksheets that present a paragraph with several punctuation errors and ask students to find and correct them develop the editing eye that children need. Pairing these exercises with a simple punctuation checklist aligned to CCSS L.2.2 helps students self-monitor their own writing.
