Word families help Kindergarten readers see patterns in short vowel words. This worksheet introduces -an, -en, -in, -on, and -un families through nine fill-in sentences and a four-pair matching activity. Children pick the correct vowel for each rhyme and match CVC words to their family. The activity builds phonics fluency, rhyme awareness, and reading speed. Kindergarten teachers can use this sheet for centers, small groups, or independent practice.
