I created this worksheet for my students to practice determining if a word should be spelled with an ER, IR or UR r-controlled vowel. They write in the correct r-controlled vowel, then cut, sort and glue it where it goes. Great practice for trying out the different sounds and writing the one that looks right and familiar. Great practice for a small group, morning work, whole group guided or independent practice, seatwork during reading rotations, homework or even practice to leave for a substitute! Check out all of my other r-controlled vowel practice activities! This is a great follow-up to my other sheets in which the students have the words and circle the r-controlled vowel, then sort them. Thanks!
