How it works
Dad, mad and sad rhyme because each ends in the short a of cat and a d: that is the ad word family. Three lists hold 25 such words, and a fourth keeps head, road and salad apart.

Ad word family spelling words, shortest first
List 1 is the nine three-letter words: bad, dad, fad, had, lad, mad, pad, sad, tad. List 2 puts two letters in front: glad, clad, brad, grad, shad. List 3 has eleven longer words that keep the rhyme, such as granddad, doodad and nomad.
Pads to write on, land on and walk on
Six words on List 3 end in pad. In the American Heritage Dictionary a notepad is a pad of paper, a keypad a set of keys, a kneepad a covering that protects the knee, a helipad a place where helicopters land, and a footpad the cushion under an animal's toes.
- Mad, sad and glad double the d before -er and -est: madder, saddest, gladdest. Bad takes neither: the dictionary gives worse and worst.
- Had is the past tense of have, and clad is a past form of clothe.
- A brad is a thin wire nail, a shad is a fish and a crawdad is a crayfish.
Questions and answers
Are these ad word family worksheets for kindergarten?
List 1 fits kindergarten best: nine three-letter words that change only the first letter. Move on to List 2 once gl, br and sh are known. Both print as a Test sheet or a Missing letters sheet.
Does add rhyme with dad?
Yes. The American Heritage Dictionary writes add as (ăd), the ending of dad and glad. It is spelled with two d's, so it is not on these lists. Plaid rhymes too: its ai is said as short a.
Do head and road belong to this word family?
No. Both end in the letters a and d, but ea spells short e in head, bread, thread, spread and instead, and oa spells long o in road, toad and load. All eight are on List 4.
Why does wad not rhyme with dad?
The dictionary gives wad (wŏd) and squad (skwŏd) a short o, not the short a of dad. In salad and ballad the last syllable is unstressed and its vowel is weak. All four are on List 4.
