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

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.
