About this resource

Description

This letter o word families worksheet helps first graders read and spell words that share the same ending. A word family is a group of words with the same ending sound and spelling pattern, like boat and goat or pot and spot. Here children compare two letter o families side by side: the long o sound in -oat and the short o sound in -ot. Seeing how one extra letter changes the vowel sound helps them read new words quickly and with confidence.

How to Use This Worksheet

Students read the twelve words in the word box at the top of this letter o word families worksheet. Then they sort each word into the correct word family by writing it on a line in the -oat card or the -ot card. A bright picture of a boat and a pot reminds children what each family sounds like. Have students read each word aloud before they write it, and point to the ending as they say it.

What’s Included

  • One printable word family sorting page with a word box of twelve letter o words
  • Two word family cards, -oat and -ot, with six writing lines each
  • A complete answer key for quick checking

Why This Worksheet Helps Kids

First, sorting by word family builds strong phonemic awareness, because children must listen for the ending sound in every word. Second, putting -oat beside -ot shows students that the letters oa make the long o sound, a key step in learning vowel teams. Third, words like float, spot and trot mix in beginning blends, so students practice blending sounds while they read and write.

Ideas for Teachers and Parents

Use this first grade word families worksheet as a phonics center, a morning work page, or homework after a lesson on the letter o. Ask children to think of one more word for each family, such as cot or throat, and say it in a sentence. You can also read the finished columns together as a rhyming chant to build reading fluency.
