Teacher's field guide

What Students Need to Do: Students read one-syllable words and listen to the vowel sound. They tell whether it is short, as in cap, or long, as in cape.
What Mastery Looks Like: A student reads pin and pine correctly and names the short i and long i sounds. They can do the same with new word pairs.
Common Misconceptions: Some students think a long vowel is one they hold for a longer time. Others read cap and cape the same way or say the final e aloud.
How to Assess It: Write tap, tape, kit, and kite on an exit ticket. Have students read each word aloud, circle the long-vowel words, and underline the short-vowel words.

Lesson moves

Use letter tiles to build cap, add e to make cape, then repeat with kit and kite while saying each word.
Ask, 'What happens to the vowel sound when cap becomes cape?' Have partners say both words and explain the change.
Play a card game: partners flip a word card, read it aloud, and keep it if they name its vowel sound correctly.
Give students a grocery flyer to find and read milk and rice, then name the vowel sound in each word.
