This worksheet lets kids practice open and closed syllables. Open syllables occur when a vowel is at the end of a syllable and makes a long vowel sound - named an "open syllable" because the vowel is not closed in by a consonant. For example, the first syllable in "baby," "be-" Closed syllables occur when a syllable ends with a consonant, making the vowel sound short. They are named a "closed syllable" because the syllable ends, or is "closed," with a consonant. For example, the first syllable in "rabbit," "rab-".
