Teacher's field guide

What Students Need to Do: Students read and spell words with vowel pairs, such as ai in rain and oi in coin. They check that the vowel sound fits the whole word.
What Mastery Looks Like: A student reads train, beach, soil, and shout without splitting the vowel pairs into separate syllables. When those words are dictated, they spell the vowel pairs correctly.
Common Misconceptions: Students may read coin as two syllables or spell rain as rane. They may think ea always makes the same sound, even in words like team and bread.
How to Assess It: Ask students to read train and coin aloud. Then dictate beach and shout for them to spell on an exit ticket.

Lesson moves

Use letter tiles to build rain, team, coin, and cloud, then have students read each word and point to its vowel pair.
Write team and bread on the board; ask students to read both and describe how the sound of ea changes.
Play vowel-pair bingo: students mark ai, ea, oi, or ou when you say rain, team, coin, or cloud.
Show a peach cobbler recipe listing peaches, flour, and oil; students underline vowel pairs, read the words, then write them from memory.
