What This Standard Means
What Students Need to Do
- Students break unfamiliar words into roots, base words, prefixes, and suffixes. They use the meanings of those parts, along with context, to work out a definition.
What Mastery Looks Like
- Students identify meaningful word parts and explain what each part contributes. They combine those meanings with sentence clues to define an unfamiliar word accurately.
Common Misconceptions
- Students may treat any word beginning or ending the same way as if it shares an affix. They may also rely only on context or confuse a base word with a root.
How to Assess It
- Give this exit ticket: “Subterranean animals live underground. What does subterranean mean? Underline its word parts and explain how they support your answer.”
