What This Standard Means
What Students Need to Do
- Students break longer words into syllables and use vowel patterns to read each part. They find prefixes, base words, and suffixes, then use those parts to spell words they hear.
What Mastery Looks Like
- A student reads basket, robot, and unhelpful without guessing from the first letters. They can show where each word breaks and spell words with similar patterns, such as picnic and replay.
Common Misconceptions
- Students may split robot as rob-ot and use a short o sound instead of reading ro-bot with a long o. They may count both vowels in rain as separate syllables or spell basket as baskit.
How to Assess It
- Give students a slip with basket and unhelpful. Have them mark the syllable breaks, read both words to a partner, then spell robot from dictation.
Lesson moves
Ways to Teach It
Give pairs letter tiles to build sunset, rabbit, and hopeful; have them mark the syllables, then rebuild each word from dictation.
Ask students to explain why basket begins with a closed syllable but robot begins with an open syllable, using the first vowel sound as evidence.
Play a word-sort relay with basket, rabbit, robot, and music; teams sort by first syllable, then read each word aloud.
Bring in a grocery flyer; students mark syllables in banana and tomato, read the words, then cover and spell them.
