Word families

Word families, built from real words

A word family is a set of words that share a rime, the vowel and everything after it: cat, hat and flat share -at. These pages list every family in our lexicon with a word ladder and teaching ideas.

The answer

A word family is a group of one-syllable words that share a rime, such as -at in cat and flat. Our 28 pages cover 2,309 different public words: single-family pages for the biggest rimes, and pages by vowel sound for the rest.

Families are keyed by spelling and sound together, so -ead in bead and -ead in bread are separate families, and -ow in snow is apart from -ow in cow. A rime gets its own page only when it has at least 15 words a student can practice; smaller families appear on the page for their vowel sound.

Use families for fluency and rhyme, not as a replacement for blending. A student who can read every word in the -ack family should still be able to sound out a new word that fits no family at all.

Questions people ask

What is a word family?

A set of words that share a rime: the vowel and the letters after it. Cat, flat and splat are in the -at family. Teachers use families to practice reading many words from one known chunk.

Why are some common families missing their own page?

A family gets its own page only with 15 or more words a student can practice from our lexicon, after leaving out words used in our assessments. Smaller families, like -op and -it, are on the page for their vowel sound.

How many word families should a student learn?

There is no fixed number. Teach families as a way to practice the sound and spelling patterns in your sequence, a few at a time, and move on once a student reads a family's words accurately without guessing.
