1st grade r-controlled vowels (ar, or, er) worksheets

The kind of words you'll sort

Say each word, then write it under its bossy r sound.

Columns: ar and or and er, ir, ur. "chart" belongs under ar; "orbit" belongs under or; "stir" belongs under er, ir, ur.

Every print pulls a fresh set of word lists at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

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

How to teach this

Lead with the ear, not the letters: say car, corn, and bird slowly and let your child hear three different endings. The fun of calling r "bossy" is real pedagogy; it explains why sounding out the short vowel fails. Read every word aloud before it's sorted.

Watch for: Er, ir, and ur all make the same sound; only the spelling differs (her, bird, fur). The r changes the vowel completely; sounding out c-a-r with a short a gives the wrong word.

Common questions about r-controlled vowels (ar, or, er)

What is a bossy r in simple terms?
When r follows a vowel, it takes over and the pair makes one new sound. Car isn't c-a-r with a short a; it's c plus the ar sound. Kids who learn to spot the vowel-plus-r team stop stalling on words that refuse to sound out the normal way.
Why are er, ir, and ur in one column together?
Because they make exactly the same sound. Her, bird, and fur rhyme in the middle even though the spellings differ. Grouping them by sound keeps the first-grade job honest: hear the sound, find the column. Sorting the three spellings apart comes later.
