CCSS.ELA-Literacy.L.5.4b
The Standard
Use common, grade-appropriate Greek and Latin affixes and roots as clues to the meaning of a word (e.g., photograph, photosynthesis).
Common Core State Standards for English Language Arts
What This Standard Means
Students need to use familiar Greek and Latin roots, prefixes, and suffixes to make a smart guess about an unknown word. They should notice word parts like photo, tele, bio, re, pre, and able, then connect those parts to meaning in the sentence.
Mastery looks like explaining both the word part and the context clue. For example, “photosynthesis has photo, which means light, and the sentence is about plants using sunlight.” Students often get stuck when a word part has more than one meaning, or when they guess from the root but ignore the sentence.
Ways to Teach It
- Give pairs root cards and word cards, then have them match photo, tele, bio, pre, and re to words and meanings.
- Ask students to write: How can knowing one root help you figure out three new words? Use examples.
- Show five unknown words with familiar roots, and have students underline the root and write a likely meaning.
- Have students find three root-based words on food labels, signs, or websites, then explain what each word part means.
