Common Core State Standards for English Language Arts

What This Standard Means

Students need to infer the meaning of unfamiliar words by using nearby clues. They should look at the full sentence, the paragraph, tone, examples, contrasts, and the word’s job in the sentence. They also need to explain what clue helped them, not just guess.

Mastery looks like a student naming a reasonable meaning, backing it with context evidence, and revising if the meaning does not fit. Students often get stuck by grabbing one nearby word, ignoring contrast words like however, or choosing a dictionary meaning that does not fit the passage.

Ways to Teach It

  • Give pairs a paragraph with five bold words, then have them underline clues and write a one-word meaning above each bold word.
  • Ask students, “Which words around the unknown word helped you most, and why?” using a short passage from the current reading.
  • Display one sentence with an unfamiliar word and four possible meanings, then have students choose and cite the exact clue.
  • Bring in a news headline or sports recap with one hard word, then have students infer its meaning before checking a dictionary.
