What This Standard Means
What Students Need to Do
- Students notice common prefixes and suffixes attached to familiar words. They use those word parts to predict how the meaning changes.
What Mastery Looks Like
- A student can separate a familiar base word from a common affix. The student explains the new word using the meaning of both parts and checks it in a sentence.
Common Misconceptions
- Students may ignore the affix and give only the base word's meaning. They may assume the same affix changes every word in exactly the same way.
How to Assess It
- Give students the words unhappy, replay, and helpful in short sentences. Ask them to circle each affix and explain the new word.

Ways to Teach It
Attach prefix and suffix cards to familiar base-word cards, then act out or draw each changed meaning.
Ask, ‘How does adding un- change happy, and how do you know the new meaning fits?’
Play Affix Match by pairing common affixes, base words, and pictures of the resulting meanings.
Find affixed words on classroom labels or directions and explain how each word part helps readers.
