CCSS.ELA-Literacy.RF.2.3d
The Standard
Decode words with common prefixes and suffixes.
Common Core State Standards for English Language Arts
What This Standard Means
Students need to read longer words by spotting familiar word parts at the beginning and end. They should know that parts like re-, un-, -ful, -less, -er, and -ed can change a word’s meaning and help them read it without guessing.
Mastery looks like a student circling the base word, naming the added part, reading the whole word, and explaining the meaning. Students often get stuck when the base word changes, like happy to unhappy, or when -ed sounds different in jumped, played, and wanted.
Ways to Teach It
- Give students word cards with bases, prefixes, and suffixes, then have them build, read, and sort words like redo, unkind, helpful, and teacher.
- Ask students to write one sentence using a word with un- and one with -less, then explain how the word part changes the meaning.
- Show five words on a whiteboard, have students underline the base word, circle the prefix or suffix, and read each word aloud.
- Bring in labels, signs, or book pages and have students hunt for words with re-, un-, -ful, -less, -er, or -ed.
