A syllable is open when it ends in a vowel, as in the first syllable of robot: ro. The vowel in an open syllable says its name, so ro sounds like row. A syllable is closed when it ends in a consonant, as in the first syllable of rabbit: rab. The vowel in a closed syllable makes its short sound. Knowing the difference helps a second grader read long words that they have not seen before, because the end of the first syllable tells what the vowel says.
This worksheet gives ten sets of three words that have been divided into syllables with a hyphen. On odd-numbered sheets the child circles the word whose first syllable is open, and on even-numbered sheets the one whose first syllable is closed. Ask your child to look at the last letter of the first chunk.
What your child will learn
Tell an open syllable from a closed syllable
Know that an open syllable ends in a vowel that says its name
Use the end of the first syllable to read a new word
Common Core standard: RF.2.3.C
Worked example
The words are rab-bit, nap-kin and ro-bot. The first syllables are rab, nap and ro. Ro ends in a vowel, so it is open. Circle ro-bot.
Common mistake
Looking at the whole word instead of the end of the first syllable.
Helpful hint
Look at the last letter of the first chunk. A vowel means open, a consonant means closed.
