This tests contractions. "We're" means "we are." The apostrophe shows where the "a" is missing.

This tests possessives. "Dog's" shows one dog owns the bowl. The apostrophe and "s" mean "belongs to."

We use apostrophes to show ownership. Emma's means it belongs to Emma. Add apostrophe and 's' to show one person owns something.

This tests possessive names. We add apostrophe + s to Emma to show ownership. 'Emma's book' means the book belongs to Emma.

This tests finding possessive words. 'Teachers' needs an apostrophe to show the desk belongs to the teacher. It should be 'teacher's desk.'

This tests CCSS.L.2.2.c (using apostrophes to form contractions and frequently occurring possessives). An apostrophe (') has two main uses in grade 2: (1) CONTRACTIONS: When we combine two words into one shorter word, the apostrophe takes the place of the missing letter(s). Examples: do not → don't (apostrophe replaces "o"), cannot → can't, I am → I'm, it is → it's, you are → you're, they are → they're, I will → I'll. (2) POSSESSIVES: To show that something belongs to someone, we add apostrophe + s ('s) to the end of a singular noun. Examples: Emma's book (book belonging to Emma), dog's collar (collar belonging to dog), teacher's desk (desk belonging to teacher). Watch out for confusing pairs: it's = it is (contraction), its = belonging to it (possessive, no apostrophe); you're = you are (contraction), your = belonging to you (possessive, no apostrophe); they're = they are (contraction), their = belonging to them (possessive, no apostrophe). Choice B is correct because "teacher's desk" shows possession with 's after the singular noun teacher, meaning the desk belongs to the teacher. Choice C "teachers' desk" fails because it uses a plural possessive form incorrectly for a single teacher, and second graders often confuse singular and plural possessives. To help students: Create two anchor charts: (1) POSSESSIVES: Show teacher + 's = teacher's desk for singular. Formula: [person] + 's = belonging to [person]. Practice "Whose desk?" → "teacher's desk," and watch for errors like missing apostrophes or adding them for plurals.

Choice A is correct because "didn't" places the apostrophe between "did" and "nt" to form the contraction for "did not," replacing the "o" in "not." Choice B "di' dnt" fails because it puts the apostrophe in the wrong place and splits the word oddly, and second graders often misplace apostrophes like didn' t instead of didn't. To help students: Create two anchor charts: (1) CONTRACTIONS: Show did + not = didn't. List contractions like didn't, doesn't. Practice expanding: "didn't" → "did not," and use physical apostrophe activities where students insert it correctly in "didnt."

Choice B is correct because "your" is the possessive form without an apostrophe, meaning the book belongs to you in "your book is on the desk." Choice A "you're" fails because it is the contraction for "you are," which would incorrectly make the sentence "you are book is on the desk," and second graders often confuse you're (you are) with your (belonging to you). To help students: Create two anchor charts: (1) CONTRACTIONS: List you're = you are. (2) POSSESSIVES: Show your = belonging to you (no apostrophe). Teach confusing pairs with visuals: you're (you are) vs your (your book), and practice sentences like "Your book" vs "You're nice."

Choice C is correct because "can't" is the contraction for "cannot," with the apostrophe replacing the missing "no" in "not." Choice B "ca'nt" fails because it puts the apostrophe in the wrong place, and second graders often misplace apostrophes in contractions like ca'nt instead of can't. To help students: Create two anchor charts: (1) CONTRACTIONS: Show cannot + apostrophe = can't. List contractions like can't, don't, won't. Practice with physical apostrophe: Students hold cards and stand where the apostrophe goes in "cannot" on the board.

Choice B is correct because "Emma's backpack" shows possession with 's after the singular noun Emma, meaning the backpack belongs to Emma. Choice A "Emmas backpack" fails because it is missing the apostrophe, and second graders often forget apostrophes in possessives like Emmas instead of Emma's. To help students: Create two anchor charts: (1) POSSESSIVES: Show apostrophe + s pattern for singular ownership (Emma + 's = Emma's book). Formula: [person/thing] + 's = belonging to [person/thing]. Practice forming possessives: "The backpack belongs to Emma" → "Emma's backpack," and play "Whose ___ is this?" games like "Whose backpack?" → "Emma's backpack."
