This tests contractions. 'She's' means 'she is.' The apostrophe replaces the 'i' in 'is.'

This tests showing ownership. We add apostrophe + s to show one dog owns something. 'Dog's collar' means the collar belongs to one dog.

We use apostrophes in contractions. Didn't means 'did not.' The apostrophe goes where the 'o' is missing.

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 "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 "It's" is the contraction for "it is," with the apostrophe replacing the missing "i" in "is," fitting the sentence "It's raining today" meaning "It is raining today." Choice A "Its" fails because it is the possessive form without an apostrophe, which would incorrectly mean "belonging to it" raining, and second graders often confuse it's (it is) with its (belonging to it). To help students: Create two anchor charts: (1) CONTRACTIONS: Show how two words combine with apostrophe replacing missing letters (it + is = it's). (2) POSSESSIVES: Show apostrophe + s pattern for singular ownership (dog + 's = dog's collar). Practice confusing pairs with visuals: it's (it is - two words) vs its (its tail - one word, no apostrophe), and play contraction sorting games where students match phrases like "it is/it's."

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

Choice B is correct because "They're" is the contraction for "they are," with the apostrophe replacing the "a" in "are," fitting "They're playing tag" meaning "They are playing tag." Choice A "Their" fails because it is the possessive form, which would mean "belonging to them playing tag," and second graders often confuse they're (they are) with their (belonging to them). To help students: Create two anchor charts: (1) CONTRACTIONS: Show they + are = they're. Teach confusing pairs with visuals: they're (they are) vs their (their toys). Practice sentences like "They're coming" vs "Their toys," and use sorting activities.

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 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."

Choice B is correct because "don't" shows the apostrophe in the correct place replacing the missing 'o' in the contraction for "do not." Choice A is incorrect because "dont" is missing the apostrophe, a common mistake where second graders forget to add it in contractions. To help students, create two anchor charts: (1) CONTRACTIONS: Show how two words combine with apostrophe replacing missing letters (do + not = don't, I + am = I'm, it + is = it's, you + are = you're). List frequently used contractions: can't, don't, won't, isn't, didn't, doesn't, I'm, it's, that's, you're, we're, they're, I'll. (2) POSSESSIVES: Show apostrophe + s pattern for singular ownership (Emma + 's = Emma's book, dog + 's = dog's collar). Practice expanding contractions: See "can't" → ask "What two words?" → cannot.
