Read words with inflectional endings.
Common Core State Standards for English Language Arts
Teacher's field guide
What This Standard Means
What Students Need to Do
- Students find a familiar base word inside a longer word. They blend endings such as -s, -es, -ed, and -ing with the base word.
What Mastery Looks Like
- Students read words such as jumps, wishes, played, helped, and running accurately. They recognize the base word and use the ending to understand the word.
Common Misconceptions
- Students may read jumped as jump or pronounce every -ed ending as /ed/. They may miss the base word when its spelling changes in running or making.
How to Assess It
- Give students the words jumps, wishes, played, helped, and running. Ask them to underline each ending and read every word aloud.
Lesson moves
Ways to Teach It
Use letter tiles to build jump, jumps, jumped, and jumping, then have students read each form aloud.
Write and answer: How does adding -ed or -ing change the action in played and playing?
Play an ending sort with word cards labeled -s, -es, -ed, and -ing, then read each sorted word.
Read a lunch menu or class note, circle words with endings, and read them aloud.
