Teacher's field guide
What This Cluster Means
What Students Need to Do
- Students use letter sounds and spelling patterns to read and write one-syllable and two-syllable words. They read and spell words with endings like -ed and -ing and parts like un-, re-, and -ful. They apply spelling rules, such as doubling the p in hopping.
What Mastery Looks Like
- A student reads ship, dollar, jumped, replay, and helpful without guessing from the first letter. They spell hopping with two p's and can point out the added parts in replay and helpful.
Common Misconceptions
- Students may read hopping as hoping or spell it with one p. They may skip un- in unhappy or guess a two-syllable word after reading only its first syllable.
How to Assess It
- Have students read ship, hopping, basket, replay, and helpful aloud. Then dictate ship, hopping, kidney, unhappy, and careless for them to write.
Lesson moves
Ways to Teach It
Give students letter tiles and suffix cards to build hop, hopping, hope, and hoping, then sort by whether the consonant doubles or e drops.
Write replay and playful on the board. Partners circle play and explain how each added word part changes its meaning.
Play a card draw: students read ship, dollar, jumping, replay, or helpful, then point to any syllable break or added word part.
Show a lunch menu listing carrots, apples, and muffins; students read the foods and write a lunch order using two plural words.
