1st grade short u word families worksheets
Short u rounds out the vowel set. First graders sort -ug, -ump, and -uck words, handle a two-consonant ending as a single chunk, and see the ck rule one more time, which by now feels like an old friend.

Every version prints on US Letter or A4, with its answer key on the last page.
How to teach this
Close the vowel tour with a little ceremony: five vowels, fifteen families, and a reader who can sort them all. Mixing this sheet with an earlier vowel's sheet makes a strong review, since the columns now compete across vowels, not just endings.
Watch for: The -ump family ends with two consonants; the family chunk keeps them together so children don't decode them separately. Duck and truck end in ck, the usual ending for a k sound after a short vowel.
Common questions about short u word families
- What do the fifteen families add up to?
- A decoding toolkit that covers a large share of one-syllable English. A first grader who owns these endings reads new words by analogy (if I can read duck, I can read cluck) which is precisely the skill the phonics standards are building toward.
- What comes after word families?
- Longer vowel patterns: silent e, vowel teams, and the rest of the phonics ladder. The sorting habit built here transfers directly, and our sight-word sheets make a good companion in the meantime.
