Vowels

R-controlled vowels

When r follows a vowel it changes the vowel's sound entirely: ar in car, or in for, and er, ir and ur all saying the same sound in her, bird and turn. These are neither long nor short, which is why readers who have only met those two categories get stuck here.

The hard part is spelling rather than reading: er, ir and ur usually sound identical, so which one a word takes has to be learned word by word. Sometimes called bossy r.

Curricula that teach this

Cody generates material against the scope and sequence you already teach. This skill appears in Cody Curriculum, Custom Pattern Selection, UFLI Inspired.

Common questions

Why do er, ir and ur sound the same?

Because in most English words they are the same sound. Which spelling a word uses is a matter of that word's history, so it is learned by word rather than by rule.

Make a decodable story for this skill

Cody generates stories, word lists and worksheets constrained to the patterns a student has already been taught, so practice on r-controlled vowels does not smuggle in something they have not met yet.
