What This Standard Means
What Students Need to Do
- Students split longer words into a prefix, base word, and ending. They blend the parts to read the whole word. They use those parts to help determine meaning.
What Mastery Looks Like
- Students can mark the parts in words such as unhappy, replayed, wishes, running, faster, and tallest. They read each word accurately and recognize that some endings have more than one sound. They can decode new examples, not just memorized words.
Common Misconceptions
- Students may read the base word but skip or guess the prefix or ending. They may assume -ed and -s always have one sound. They may confuse -er and -est with word parts that do not act as endings, as in her or nest.
How to Assess It
- Give students unhappy, replayed, dishes, running, faster, and tallest. Have them mark each base word and added part, then read every word aloud.

Ways to Teach It
Use prefix, base-word, and ending cards to build and read words such as unhappy, replayed, wishes, and fastest.
Ask, “How do un-, re-, and dis- change a base word?” Students write one example and explain its meaning.
Play word-part bingo: call “re plus play plus ed,” and students cover replayed, then read it aloud.
Hunt for prefixed and inflected words on classroom signs, schedules, and book covers, then explain each word’s parts.
