The Standard
Identify frequently occurring root words (e.g., look) and their inflectional forms (e.g., looks, looked, looking).
Common Core State Standards for English Language Arts
What This Standard Means
Students need to notice that words can change endings and still keep the same basic meaning. They should connect a base word like jump to jumps, jumped, and jumping, then use those forms correctly when reading, speaking, and writing.
Mastery looks like a child saying, “They all come from play,” and explaining how the ending changes the time or who is doing it. Students often get stuck when the spelling changes, like drop to dropped, or when they treat each form as a totally new word.
Ways to Teach It
- Use word cards for walk, walks, walked, and walking, then have students sort cards under the matching base word.
- Ask students to finish this prompt: “I can read, I am reading, Yesterday I ___.”
- Show three word forms and ask students to circle the one that tells about yesterday.
- Look at classroom labels or a picture book page and find words with endings like -s, -ed, and -ing.
