How to use this quiz

Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

Question 1

1. walk
2. walking (correct answer)
3. walked

Explanation: We are finding action happening now. The word 'walking' shows action happening right now. The -ing ending tells us it's happening now.

Question 2

1. dish (correct answer)
2. dishe
3. dis

Explanation: Dish is correct because it is the smaller word inside dishes before the ending -es is added. Dishe is not a real word on its own. Dis is only part of the word and is missing the rest of the base word. Only dish is the complete base word.

Question 3

1. -s (correct answer)
2. -es
3. -ing

Explanation: We look at word endings carefully. The word 'dogs' ends with just '-s'. This '-s' makes it mean more than one.

Question 4

1. looked
2. looking (correct answer)
3. looks

Explanation: The word 'now' tells us it's happening. We use '-ing' for things happening now. So 'looking' is the right word.

Question 5

1. -es (correct answer)
2. -ing
3. -s

Explanation: We are finding word endings. The word 'wishes' ends with -es. We add -es after sh sounds.

Question 6

1. jumped
2. jump (correct answer)
3. jum

Explanation: We find base words by taking off endings. The word 'jumped' has the ending '-ed'. When we take off '-ed', we get 'jump'.

Question 7

1. helping
2. hel
3. help (correct answer)

Explanation: We are finding the base word. The base word is 'help'. We take away the -ing to find the main word.

Question 8

1. -ing
2. -ed (correct answer)
3. -s

Explanation: We are finding the word ending. The word 'played' has the -ed ending. The -ed tells us it already happened.

Question 9

1. helped
2. help (correct answer)
3. hel
4. helps

Explanation: Help is the base word because it is the simplest form before any ending is added, so B is correct. Helped is the base word with -ed added to show the past. Hel is not a real word, so it cannot be the base word. Helps adds -s to show one person doing the action now.

Question 10

1. -ed
2. -s (correct answer)
3. -ing
4. -es

Explanation: This question tests reading words with inflectional endings (CCSS.RF.1.3.f: Read words with inflectional endings). Inflectional endings are word parts added to base words to change meaning: -s/-es (more than one or he/she does), -ed (happened before/past), -ing (happening now). These endings don't change the base word's core meaning, just add grammatical information. Examples: jump → jumped (did jump), cat → cats (more than one cat), play → playing (doing play). The word plays has base play plus ending -s. The base play means to have fun; the ending -s changes it to third person singular (he/she has fun). Students identify the base (familiar root) and recognize the ending to read the full word plays as /plays/. Choice D is correct because it identifies the correct ending -s, used for third person singular. This demonstrates the student recognizes the ending variation. Choice B represents the error of confusing -s with -es. This is common because students may not distinguish between -s and -es forms. To support inflectional ending reading: Explicitly teach common endings (-s, -ed, -ing) and their meanings (plural, past, present progressive). Use color-coding (base one color, ending another). Practice with familiar bases before introducing new words. Teach context clues (yesterday = past/-ed, now = -ing). Model thinking: "This word has [base] plus -[ending], so it means [meaning]." Watch for: Students who don't recognize endings and try to decode as one unfamiliar word, students who confuse -ed with -s, students who can read but don't understand meaning change. Support with pictures showing one vs many, or action completed vs ongoing.

Question 11

1. wal
2. walk (correct answer)
3. walks
4. walked

Explanation: Walk is the base word because it is the smallest form of the word before an ending is added. Wal is wrong because it is not a real word. Walks and walked are wrong because they already have endings added, just like walking does.

Question 12

1. ca
2. cats
3. cast
4. cat (correct answer)

Explanation: Cat is the base word because it is the smallest form of the word before adding an ending. Ca is wrong because it is not a real word by itself. Cats is wrong because it already has the ending -s added. Cast is wrong because it has extra letters that change the word completely.

Question 13

1. jump
2. jumps
3. jumped (correct answer)

Explanation: We are picking the right verb form. 'Yesterday' tells us it already happened. We use 'jumped' with -ed for the past.

Question 14

1. -es (correct answer)
2. -ed
3. -s

Explanation: We are looking for word endings. The word 'dishes' ends with -es. We add -es after sh sounds.

Question 15

1. jump (correct answer)
2. jumped
3. jumping

Explanation: The base word is the smallest form of the word with no ending added, which is jump. Jumped adds -ed to show something already happened, so it is not the base word. Jumping adds -ing, so it is also not the base word.

Question 16

1. -ed (correct answer)
2. -s
3. -ing

Explanation: We are finding word endings. The word 'looked' ends with -ed. This ending shows past time.

Question 17

1. -ed
2. -s (correct answer)
3. -es

Explanation: The word helps ends with the letter s, added to the word help to show one person doing the action now. The ending ed shows something already happened in the past, which does not match helps. The ending es is used for words that end in certain sounds, like box or wish, not for help.

Question 18

1. -s
2. -ed
3. -es (correct answer)

Explanation: The word boxes ends with the letters es, added to the word box to show more than one. The ending s alone is not used here because box ends in x, which needs es to be pronounced clearly. The ending ed is used to show something happened in the past, not to show more than one.

Question 19

1. -ed
2. -ing (correct answer)
3. -s

Explanation: The word playing ends with -ing, which shows an action is happening now. The ending -ed is used for actions that already happened, so it does not fit here. The ending -s is added to show one person does something, like plays, not added on top of -ing. Playing already ends in -ing, so B is correct.

Question 20

1. -s
2. -ed
3. -ing
4. -es (correct answer)

Explanation: This question tests reading words with inflectional endings (CCSS.RF.1.3.f: Read words with inflectional endings). Inflectional endings are word parts added to base words to change meaning: -s/-es (more than one or he/she does), -ed (happened before/past), -ing (happening now). These endings don't change the base word's core meaning, just add grammatical information. Examples: jump → jumped (did jump), cat → cats (more than one cat), play → playing (doing play). The word boxes has base box plus ending -es. The base box means a container; the ending -es changes it to plural (more than one box). Students identify the base (familiar root) and recognize the ending to read the full word boxes as /bok-siz/. Choice C is correct because it identifies the correct ending -es, which is used for plurals ending in x. This demonstrates the student recognizes the specific ending variation. Choice A represents the error of confusing -es with the similar -s ending. This is common because students learning to separate endings from base may not distinguish between -s and -es forms. To support inflectional ending reading: Explicitly teach common endings (-s, -ed, -ing) and their meanings (plural, past, present progressive). Use color-coding (base one color, ending another). Practice with familiar bases before introducing new words. Teach context clues (yesterday = past/-ed, now = -ing). Model thinking: "This word has [base] plus -[ending], so it means [meaning]." Watch for: Students who don't recognize endings and try to decode as one unfamiliar word, students who confuse -ed with -s, students who can read but don't understand meaning change. Support with pictures showing one vs many, or action completed vs ongoing.
