This worksheet will provide a range of exercises to help 3rd-grade students grasp inflectional endings in a fun and interactive way.

What Are Inflectional Endings?

Inflectional endings are modifications added to words to convey different grammatical meanings. These changes allow us to show plurality, tense, possession, and comparison. For example, the plural form of ‘dog’ is ‘dogs,’ and the past tense of ‘jump’ is ‘jumped.’ Understanding how and when to use these endings is vital for creating grammatically correct sentences.

Common Inflectional Endings for 3rd Graders

At this grade level, 3rd graders will encounter several key inflectional endings. Let’s take a closer look at the most commonly used ones

1. -s and -es (Plural Nouns) These endings are used to indicate more than one person, place, or thing.

   • Example cat → cats, box → boxes

2. -ed (Past Tense Verbs) Adding this ending to a verb shows that the action has already occurred.

   • Example jump → jumped, play → played

3. -ing (Present Progressive Verbs) This ending shows that an action is happening right now or is in progress.

   • Example run → running, swim → swimming

4. -‘s (Possessive Nouns) This ending shows ownership or possession.

   • Example the boy’s book, the teacher’s desk

5. -er and -est (Comparative and Superlative Adjectives) These endings are used to compare two or more things.

   • Example tall → taller → tallest
