R-controlled vowels are one of the most important phonics patterns students encounter as they move beyond basic short and long vowel sounds. When a vowel is followed by the letter r, the vowel no longer makes its expected sound. The r takes over and changes the pronunciation entirely, which is why teachers often call this pattern “bossy r.” There are five r-controlled vowel patterns: ar, or, er, ir, and ur. This guide explains each pattern with word lists, covers where r-controlled vowels fit in a structured literacy scope and sequence, shares Orton-Gillingham multisensory teaching strategies, and provides practical activities for the classroom and home.

What Are R-Controlled Vowels?
An r-controlled vowel occurs when a vowel is immediately followed by the letter r in a syllable. Instead of making its typical short or long sound, the vowel blends with the r to produce a new, unique sound. The r “controls” or changes the vowel’s pronunciation.
Consider these pairs:
- cat to car (the short /a/ becomes /ar/)
- pot to port (the short /o/ becomes /or/)
- hen to her (the short /e/ becomes /er/)
In each case, adding the letter r after the vowel shifts the sound completely. Students who have mastered CVC (consonant-vowel-consonant) words and silent e patterns often stumble when they first encounter r-controlled vowels because the rules they already know no longer apply.
R-controlled vowels create three distinct phonemes in English:
- /ar/ as in car
- /or/ as in corn
- /er/ as in her, bird, and nurse
Understanding these three sounds and the five spelling patterns that represent them is essential for accurate decoding and spelling in structured literacy instruction.
The 5 R-Controlled Vowel Patterns
AR Words (/ar/ Sound)
The ar pattern makes the /ar/ sound, as in car. This is usually the first r-controlled vowel pattern taught because it has the most distinct and recognizable sound.
One-syllable ar words: car, star, farm, park, hard, dark, bark, card, chart, sharp, start, march, art, arm, barn, jar, scar, yard, part, spark
Multisyllabic ar words: market, garden, carpet, harvest, party, target, alarm, apartment, barber, marvel
Note that ar can sometimes make the /er/ sound in unstressed syllables, as in dollar and collar. Introduce this variation later, after students are confident with the primary /ar/ pronunciation.
OR Words (/or/ Sound)
The or pattern produces the /or/ sound, as in corn. Like /ar/, this is a distinct sound that students can usually tell apart from other r-controlled vowels without difficulty.
One-syllable or words: corn, fork, storm, short, horse, sport, porch, sort, north, born, cord, fort, form, horn, port, torn, worn, thorn, torch, scorch
Multisyllabic or words: corner, morning, forest, border, fortune, organ, forty, order, orbit, fortress
Like ar, the or pattern can produce the /er/ sound in unstressed syllables, such as in doctor and mirror. Save this for a later lesson once the primary /or/ sound is solid.
ER Words (/er/ Sound)
The er pattern makes the /er/ sound, as in her. This is where r-controlled vowels get tricky for students because the same /er/ sound can be spelled three different ways: er, ir, or ur.
One-syllable er words: her, term, fern, clerk, verse, nerve, stern, swerve, jerk, perch
Multisyllabic er words: teacher, letter, summer, winter, dinner, silver, perfect, person, after, never
The er spelling is the most common of the three /er/ patterns. It appears frequently at the end of words and in the suffix -er (as in bigger, faster, and teacher).
IR Words (/er/ Sound)
The ir pattern also makes the /er/ sound, as in bird. Students may wonder why ir does not have its own unique sound. In modern American English, the vowel sound in bird, her, and nurse is identical.
One-syllable ir words: bird, girl, first, stir, dirt, shirt, skirt, swirl, third, birth, firm, chirp, squirm, twirl
Multisyllabic ir words: circle, birthday, thirty, thirteen, confirm, virtual, stirrup, spirit, thirsty, circus
The ir spelling frequently appears in the middle of words. Point this out to students as a helpful pattern to watch for when reading and spelling.
UR Words (/er/ Sound)
The ur pattern is the third spelling for the /er/ sound, as in nurse. It is less common than er but appears in many everyday words.
One-syllable ur words: burn, turn, hurt, church, nurse, curve, burst, surf, curb, purse, lurk, blur, churn, spur
Multisyllabic ur words: purple, turkey, turtle, return, Saturday, surprise, furniture, hamburger, disturb, occur
Because er, ir, and ur all make the same sound, students need explicit instruction and repeated practice to remember which spelling to use. The most effective approach is teaching high-frequency words with each pattern and building spelling rules gradually. Teaching spelling with a structured, multisensory method helps students internalize these patterns.
Where R-Controlled Vowels Fit in Reading Instruction
In a structured literacy scope and sequence, r-controlled vowels are typically introduced after students have mastered:
- Short vowel sounds (CVC words like cat, pen, sit, hot, bug)
- Consonant blends (bl, cr, st, etc.)
- Consonant digraphs (sh, ch, th, wh, ck)
- Silent e / magic e patterns (make, bike, home, cute)
This placement makes sense because students need a strong foundation in basic vowel sounds before they can understand how r changes those sounds. Introducing r-controlled vowels too early, before short vowels are automatic, creates confusion.
Most structured literacy programs teach ar and or first because they have unique, distinguishable sounds. The er, ir, and ur patterns come next, often taught together or in close sequence so students can compare and contrast the identical sounds with different spellings.
The PRIDE Reading Program follows this sequence and includes specific lessons on each r-controlled vowel pattern with built-in review and application activities.
How to Teach R-Controlled Vowels Using Orton-Gillingham Methods
The Orton-Gillingham approach uses multisensory techniques that engage visual, auditory, and kinesthetic pathways simultaneously. This method is especially effective for r-controlled vowels because students need to override their existing vowel knowledge and learn new sound-spelling connections. Research on the science of reading consistently supports this type of explicit, systematic phonics instruction.
Here is a lesson framework for teaching ar as the first r-controlled vowel:
- Introduce the concept: Tell students that when a vowel is followed by the letter r, the r changes the vowel sound. Write “cat” and “car” on the board. Have students read both words and listen to how the vowel sound changes.
- Teach the sound: Show the ar card. Say the sound /ar/ and have students repeat it. Point out that the a and r work together as a team.
- Finger spelling: Have students hold up two fingers (one for a, one for r) while saying the /ar/ sound. This reinforces that ar is a two-letter unit that makes one sound.
- Sound-symbol practice: Say a word with the /ar/ sound. Have students repeat the word, identify the /ar/ sound, and write ar on their paper or in a sand tray.
- Blending practice: Use letter tiles or a pocket chart. Build words like c-ar, st-ar, f-ar-m, p-ar-k. Have students blend the sounds together to read each word.
- Dictation: Say words with the /ar/ sound and have students spell them. Start with simple CVC-r words (car, far, bar) before moving to blends (star, charm, sharp).
- Connected text: Have students read sentences or a short passage containing multiple ar words to practice the pattern in context.
Repeat this framework for each new r-controlled vowel pattern. When you reach er, ir, and ur, spend extra time comparing the three spellings and building a reference chart students can use during writing.
Activities and Games for Practicing R-Controlled Vowels
Practice should be varied and engaging. Here are activities that reinforce r-controlled vowel patterns, using multisensory techniques aligned with the Orton-Gillingham approach:
Word Sorts
Write r-controlled vowel words on index cards. Have students sort them into columns by pattern (ar, or, er, ir, ur). Start with two categories and build to all five. This activity builds pattern recognition and helps students notice the similarities and differences between spellings.
Bossy R Board Game
Create a simple board game where each space has an r-controlled vowel word. Students read the word, identify the r-controlled pattern, and use it in a sentence to advance. This adds oral language practice to decoding work. For more game ideas, explore our collection of phonics activities.
Dictation Sentences
Create sentences loaded with r-controlled vowel words: “The girl in a purple shirt went to the park after church.” Students write the sentence from dictation, then circle all the r-controlled vowel patterns they find. This combines listening, spelling, and pattern identification in one task.
Sand or Salt Tray Writing
Fill a shallow tray with sand or salt. Say an r-controlled vowel word. Students write the word in the tray with their finger while saying each sound. The tactile feedback strengthens the connection between the sound and the spelling pattern.
Word Building with Tiles
Give students letter tiles and an r-controlled vowel tile (ar, or, er, ir, or ur). Ask them to build as many words as they can with each tile. This encourages exploration and helps students see how the r-controlled vowel chunk functions within words.
Reading Decodable Texts
Use decodable readers that focus specifically on r-controlled vowels. These texts use only phonics patterns students have already learned, so they can practice the new skill without being distracted by unfamiliar patterns. The PRIDE Reading Program includes decodable stories at each level that systematically introduce and reinforce r-controlled vowels.
Common Mistakes Students Make with R-Controlled Vowels
Knowing typical errors helps you target instruction. Watch for these patterns:
- Spelling /er/ words wrong: Students often spell “bird” as “berd” or “nurse” as “nerse” because they default to the most common er spelling. Regular word sorts and explicit instruction on which words use which spelling are the best remedy.
- Confusing ar and or: Some students mix up /ar/ and /or/ when reading quickly. Pairing these two patterns in comparison activities helps students hear and produce the difference.
- Dropping the r: In some dialects, the r sound is reduced or dropped (as in some regions where “car” sounds like “cah”). Make sure students hear a clear model of the r-controlled vowel sound during instruction.
- Overgeneralizing: After learning r-controlled vowels, some students start seeing the pattern everywhere, reading “rain” as “r-controlled” when it is actually a vowel team. Remind students that the vowel must come directly before the r in the same syllable for the r-controlled rule to apply.
Frequently Asked Questions
What grade should r-controlled vowels be taught?
Most structured literacy programs introduce r-controlled vowels toward the end of first grade or the beginning of second grade, after students have mastered short vowels and silent e. However, the right time depends on the individual student’s mastery of prerequisite skills, not their grade level. The PRIDE Placement Assessment can help you determine whether a student is ready for r-controlled vowels.
Why are er, ir, and ur taught together?
Because they all make the same /er/ sound, teaching them in close sequence helps students understand that one sound can have multiple spellings. This is an important concept in English orthography. Teaching them too far apart can actually make it harder for students to see the connection.
How long does it take students to master r-controlled vowels?
Most students need 2 to 4 weeks of focused instruction per r-controlled vowel pattern, followed by ongoing review. The ar and or patterns are typically learned faster because they have unique sounds. The er, ir, and ur patterns take longer because students must learn both the sound and the correct spelling for each word.
How do I help a struggling reader with r-controlled vowels?
Go back to the prerequisite skills first. Make sure short vowels are automatic. Then introduce one r-controlled pattern at a time with plenty of multisensory practice. Use dictation, word sorts, and decodable texts daily. If a student continues to struggle, a structured program like the PRIDE Reading Program provides scripted, systematic lessons that make it easy to deliver effective instruction at home or in the classroom.
Build a Strong Foundation with R-Controlled Vowels
R-controlled vowels are a critical step in a student’s phonics journey. Without mastery of these patterns, students will struggle with thousands of common English words. The key to success is explicit, systematic instruction that introduces one pattern at a time, uses multisensory techniques, and provides enough practice for the patterns to become automatic.
