Kids start working on r-controlled vowels in late first grade or early 2nd grade. R-controlled vowels include:
ar as in shark
er as in clerk
ir as in swirl
ur as in burn
or as in born
Introduce these sounds one at a time. Add the sound units to your student’s flashcard pile and have her review them daily.
In r-controlled words, the r “controls” the sound of the vowel. It dominates the vowel and changes the sound. Thus, these units need to be memorized. With /ar/, for example, the vowel no longer says a_ as in apple. Likewise, the r changes the sound of the e in /er/, i in /ir/, u in /ur/ and o in /or/. This is why some people call r-controlled sounds “bossy r.”

Reading Elephant has updated and improved our r-controlled vowel stories.
Reading Elephant has a new and improved set of r-controlled stories in our shop. Our r-controlled stories are leveled to help beginning readers gradually learn one sound at a time. We’ve added more pictures to some of the stories so kids can delight in the magical, sometimes goofy illustrations. We’ve also tweaked the stories to help some kids who need a gentler, more gradual approach.

Help kids spell r-controlled words.
Kids can have a tough time spelling r-controlled words and words with the letter r.
They may have trouble deciphering when to just use the letter /r/ and when to use an r-controlled sound. Thus, make sure kids practice spelling lists of words with a variety of letter r and r-controlled words–that way they can learn to spell r-controlled words correctly. For example, here is a good list at this level:
- brand
- bark
- porch
- crack
- shark
In the above list, the student has to practice the difference between the r blend as in “cr” and “br” and the r-controlled sounds ar, or.
To help kids spell r-controlled words, emphasize that there must be a vowel in every word. If they write, “shrk” for “shark,” ask them “Where’s the vowel?” The student will identify that he’s missing a vowel. Say, “If you hear an r-sound and you’re word is missing a vowel, that means you have to pick an r-controlled sound.”
Bring your student to his phonics chart. Locate the r-controlled sounds. Have him pick the correct r-sound for “shark.”
With practice, your student will begin to spell these challenging words correctly.
When spelling “brand,” your student may be tempted to pick an r-controlled sound and write “berand.” In this case, have the student identify the 2 vowels he wrote. Say, “This is a single-syllable word, it has one beat, therefore, it only needs one vowel. That means we do not need an r-controlled sound.”
R-controlled words can be tricky in spelling activities. However, this is normal. With practice, your student will spell these words right.
