The kind of words you'll sort

Say each word. Write it under its family.

Columns: -ug and -ump and -uck. "chug" belongs under -ug; "pump" belongs under -ump; "truck" belongs under -uck.

Every print pulls a new set of words at this level, so a make-up test or a second sibling gets a different mix.

What's on a kindergarten sheet

Kindergarten sheets draw from 33 words, 15 to a page. Kindergarten and 1st grade print from the same 33 words. What changes is the standard (RF.K.3 here) and the teaching notes below.

Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

The -ug family is pure fun to say and the right place to start. The -ump ending is the first two-consonant chunk many children meet; keep the chunk together (ump!) so the m and p are said as a pair, and the sort stays easy.

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 kindergarten short u word families

Is the -ump ending too hard for kindergarten?
Not when it's taught as one chunk. Children who try to sound m and p separately stumble; children who learn ump as a unit read jump and bump on the first try. The column format keeps the chunk visually whole.
What order should the five vowel sheets go in?
The classic order is a, i, o, e, u or simply a to u; the honest answer is that consistency matters more than sequence. Each sheet stands alone, so start where your child's curriculum is and circle back for the rest.
