Question 1

1. your
2. you're (correct answer)
3. your'e
4. youre

Explanation: The sentence means "You are going to win!" so you need the contraction that stands for "you are." The word you're is that contraction, and the apostrophe takes the place of the missing letter a. Try the test: "You are going to win!" still makes sense, so you're is correct. The word your shows that something belongs to you, like "your book" or "your team." You cannot say "You are going to win" as "belongs-to-you going to win," so your does not fit here. The choice your'e looks like a contraction, but the apostrophe is in the wrong place; the apostrophe must replace the missing letter in "you are," so it belongs before the letter e, not after it. The choice youre is missing its apostrophe completely, and a contraction always needs an apostrophe to show that letters were left out, so it is not spelled correctly. Only you're both means "you are" and is written the right way.

Question 2

1. their
2. there
3. they're (correct answer)
4. theirs

Explanation: The sentence needs to mean "they are going to put the bikes in the garage," so the contraction they're is correct. The word their shows ownership, like "their bikes," and cannot come before "going." The word there points to a place, like "put them over there," so it does not fit here either. The word theirs also shows ownership and stands in for something already owned, like "the bikes are theirs," so it cannot start this sentence before "going."

Question 3

1. bye
2. by
3. buy (correct answer)
4. bought

Explanation: Buy means to get something by paying money, so it fits because Carlos is getting a snack. Bye is what you say when you leave someone, so it does not name an action Carlos does to the snack. By is a small word that shows place or how something happens, like sitting by the tree, so it is not an action either. Bought is a real word that means the same as buy, but it tells about the past. The sentence uses will, which points to something that has not happened yet, so bought does not match the time word will.

Question 4

1. your
2. you're (correct answer)
3. youre
4. yours

Explanation: The blank needs a word that means "you are," because the sentence is telling Jamal, "you are going to need your library card." You can test this by expanding the word: "You are going to need your library card today" makes perfect sense, so "you're" is correct. The apostrophe in "you're" stands for the missing letter in "you are." The word "your" shows possession, like "your card," but here we are not saying something belongs to Jamal, so it does not fit. The word "youre" is just "you're" written without its apostrophe, so it is spelled incorrectly and cannot be the answer. The word "yours" also shows possession, like "that book is yours," but the sentence needs "you are," not something belonging to you. Remember: if you can swap in "you are," choose "you're"; if it shows belonging, choose "your" or "yours."

Question 5

1. our (correct answer)
2. are
3. hour
4. ours

Explanation: The blank needs a possessive word showing whose classroom it is, so our is correct. Are is a verb, not a possessive word, so it does not fit here. Hour sounds similar to our but means a unit of time, not possession. Ours is a possessive pronoun used alone, not before a noun like classroom, so it does not fit either.

Question 6

1. their
2. there
3. they're (correct answer)
4. theirs

Explanation: The word they're is a contraction that means "they are," and "They are going to play soccer" fits the sentence perfectly. The word their shows ownership, like "their soccer ball," so it does not mean "they are" and cannot start this sentence. The word there points to a place, like "over there," but the sentence is not telling about a place. The word theirs also shows ownership, like "the ball is theirs," and it never means "they are." Only they're gives you the missing words "they are," so it is the one correct choice.

Question 7

1. no
2. know (correct answer)
3. knowe
4. now

Explanation: This question tests CCSS.L.4.1.g: correctly using frequently confused words like to/too/two, there/their/they're, your/you're, its/it's, than/then, hear/here, and know/no. Students must choose the correct word based on its meaning in context. KNOW / NO: KNOW means understand ('I know that'), NO is negative ('no cookies'). In this sentence, "I   the answer, so I said it out loud," the context is about understanding or being aware of the answer and then speaking it. The meaning needed is to understand, which tells us which word to use. Choice B is correct because "know" means understand which matches what the sentence needs. The sentence is about knowing something, so we use KNOW. Choice A represents the wrong word from the confused set, which occurs when students confuse homophones KNOW and NO. Using "no" would mean negative which doesn't fit the context. To help students: Create memory aids - KNOW=knowledge (has 'know' like 'now I know'); NO=negative (short and direct). Practice substitution tests: See if it's about understanding (KNOW) or denying (NO). Watch for: mixing up homophones KNOW/NO.

Question 8

1. then
2. than (correct answer)
3. when
4. that

Explanation: The sentence compares Jamal's speed to your speed, so it needs the comparing word "than." You can remember that "than" goes with comparing (think "faster than," "bigger than"). The word "then" is wrong because it is used for time or order, like "first we ran, then we rested" — it does not compare two things. The word "when" is wrong because it asks or tells about time, and this sentence is not talking about a time. The word "that" is wrong because it points to or names something, and "faster that me" does not make sense. Only "than" fits a comparison, so it is the one correct choice.

Question 9

1. am
2. are (correct answer)
3. is
4. was

Explanation: The word "are" is the correct helping verb to pair with "we" for something happening right now: "We are cleaning." The word "am" only goes with "I," as in "I am cleaning," so it does not match "we." The word "is" is used for a single person or thing, like "she is" or "the room is," not for "we." The word "was" shows past time, but the words "right now" tell you the action is happening in the present, so a past-tense verb does not fit.

Question 10

1. too
2. two (correct answer)
3. to
4. tow

Explanation: The sentence tells how many kittens Maya has at home, so you need a number word. "Two" means the number 2, which is exactly what counts the kittens. "Too" means "also" or "more than enough," like "too hot" — it does not name a number, so it doesn't fit. "To" shows direction or goes in front of a verb, like "go to school" or "to run," so it cannot count kittens either. "Tow" means to pull something, like a truck that can tow a car — it sounds a little like the others but has a different meaning and does not tell how many. Since the sentence is about counting kittens, the number word "two" is the only choice that makes sense.

Question 11

1. then
2. than (correct answer)
3. thin
4. when

Explanation: The sentence compares how fast Jamal is next to you, so you need the comparing word: "than." You use "than" whenever you put two things side by side, like "taller than" or "faster than." The word "then" tells about time or what happens next, like "first we ran, then we rested"—but nothing in this sentence is about time order, so it does not fit. The word "thin" means skinny or not thick; it describes what something looks like, and it makes no sense in a comparison about speed. The word "when" asks about time too, and it turns the sentence into a question part instead of a smooth comparison, so it does not work here. A quick trick: if you are comparing two things, choose "than." Only "than" does the comparing job this sentence needs.

Question 12

1. bye / buy / by
2. buy / by / bye (correct answer)
3. bye / by / buy
4. buy / bye / by

Explanation: The sentence needs three homophones that sound alike but mean different things. The first blank is about getting the snack, so you need buy, which means to purchase something. The second blank tells where the store is, so you need by, which means near or beside. The last blank is a farewell, so you need bye, which is short for goodbye. That makes buy / by / bye the correct answer. The choice starting bye / buy / by is wrong because it says goodbye first and buy where the location word belongs. The choice bye / by / buy is wrong because you cannot start by saying goodbye and then purchase the store itself. The choice buy / bye / by gets the purchase right but says goodbye to the store and puts the location word at the end for the farewell. To check your answer, try swapping in the meanings: 'purchase' for buy, 'near' for by, and 'goodbye' for bye. Only one order makes sense in the sentence.

Question 13

1. there (correct answer)
2. their
3. they're
4. theirs

Explanation: The sentence tells where to put your shoes, so you need the word that means a place. "There" points to a location, like "over there," so "Put your shoes in there by the door" is correct. "Their" shows that something belongs to a group of people, like "their shoes," but shoes cannot belong to a spot by the door, so it does not fit. "They're" is short for "they are" — try reading it as "Put your shoes in they are by the door," and you can hear that it makes no sense. "Theirs" also shows ownership by a group, like "the shoes are theirs," so it names something people own instead of a place, which is wrong here. Tip: if the sentence is about a place, choose "there," because "there" has the word "here" hiding inside it, and "here" is also about place.

Question 14

1. too
2. two (correct answer)
3. to
4. tow

Explanation: The sentence tells how many notebooks Keisha has, so it needs the number word "two." The word "too" means "also" or "more than enough," so it does not tell an amount here. The word "to" shows direction or begins a verb phrase, like "to run," so it does not fit either. The word "tow" means to pull something, like a truck towing a car, so it does not make sense with notebooks. Only "two" names the number of notebooks Keisha has.

Question 15

1. your
2. you're (correct answer)
3. you'll
4. yours

Explanation: The blank needs a word that means "you are," because the sentence tells Chen, "you are my partner for the science project today." "You're" is the contraction of "you are," and the apostrophe shows that the letter a was left out. Try the substitution test: "Chen, you are my partner" makes sense, so "you're" is correct. "Your" shows possession, like "your book" or "your pencil" belongs to you; saying "Chen, your my partner" does not work because it does not mean "you are." "You'll" is the contraction of "you will," so it points to the future; "Chen, you will my partner" does not make sense in this sentence. "Yours" is a possessive word that stands alone, like "that project is yours," so "Chen, yours my partner" also does not work. Only "you're" passes the "you are" test, so it is the one best answer.

Question 16

1. no
2. know (correct answer)
3. knew
4. now

Explanation: Know fits because the sentence describes someone currently having the answer in their mind before saying it aloud. No is used to say a negative, not to describe knowing something. Knew is the past tense form, but the sentence describes the present moment of speaking. Now describes time, not the act of knowing something.

Question 17

1. you'r
2. you're (correct answer)
3. yours
4. youre

Explanation: You're is the contraction for you are and fits because the sentence means someone is going to win. You'r is missing the letter e and is not a real word. Yours shows possession and does not fit the meaning of the sentence. Youre is missing the apostrophe needed to form the contraction correctly.

Question 18

1. their
2. there
3. they're (correct answer)
4. them

Explanation: They're is a contraction of "they are," and "They are going to play soccer" makes sense, so they're is correct. Their shows who owns something, like "their ball," so it does not fit before "going." There points to a place, like "over there," so it does not fit either. Them is used as an object, like "pass it to them," and cannot start this sentence the way "they are" does. Only they're completes the sentence correctly.

Question 19

1. too
2. two (correct answer)
3. to
4. tow

Explanation: The word two is the number that tells how many kittens Maya has, so it fits the sentence. Too means "also" or "very much," like in "I want one too," so it does not tell an amount. To shows direction or goes before a verb, like in "go to school," so it does not fit here either. Tow means to pull something, like a truck that can tow a car, and it does not tell how many. Only two names a number, so it is the correct answer.

Question 20

1. to
2. too
3. two (correct answer)
4. tow

Explanation: The blank tells how many red markers Maya has, so it needs the number word. Two is the word that means the number 2, which fits perfectly. To shows direction or purpose, like going to a place, so it cannot count markers. Too means also or more than enough, like wanting markers too, which does not tell an amount. Tow means to pull something along, like a truck that can tow a car, and that has nothing to do with counting. Only two names a number, so it is the correct choice.
