I created this color sorting activity to provide additonal practice for the students in recognizing the ER, IR and UR R-Controlled Vowel in a word. This activity provides extra reinforcement and exposure to many words that contain an ER, IR or UR R-Controlled Vowel. The directions ask the students to color the boxes different colors based on if they hae an ER, IR or UR. Great review and practice for morning work, seatwork during literacy centers or even homework! Check out all of my other R-Controlled Vowel Team Activities, including cut and paste sorts for the ER, IR and UR r-controlled vowels, as well as a cut and paste sort for AR, ER, IR, OR and UR. I also have short and long vowel sorts, digraph sorts, etc. Check out my Language Arts category in my store! Thanks!
