These Elkonin Boxes are a wonderful way to reinforce that r-controlled vowels make a single sound. These boxes focus on r-controlled "a." I love to use these boxes as I am teaching r-controlled vowels to help guide students' tapping of sounds in words. The pictures in this activity provide a noun that students will tap and write the sounds in the boxes provided.
These boxes work well for me both in one-on-one and small-group settings. I hope your students can benefit from these, as well!
