CCSS.ELA-Literacy.RF.3.3a
The Standard
Identify and know the meaning of the most common prefixes and derivational suffixes.
Common Core State Standards for English Language Arts
What This Standard Means
Students need to spot common prefixes and suffixes in words, then use them to figure out meaning. They should know that parts like un-, re-, pre-, -ful, -less, and -ness change a base word in predictable ways.
Mastery looks like a student breaking a word into parts, explaining what each part means, and using the word correctly in a sentence. Students often get stuck when the spelling changes, as in happy to happiness, or when a word part looks familiar but is not acting as a prefix or suffix.
Ways to Teach It
- Give pairs word cards and affix cards, then have them build words like replay, careful, and kindness and explain each meaning.
- Ask students to write: How does adding un-, re-, or -less change the meaning of a word? Use three examples.
- Show five words on the board, and have students underline the prefix or suffix and write a quick meaning for each word.
- Bring in cereal boxes, book titles, or ads, and have students hunt for words with prefixes and suffixes in real print.
