I use this technique with my pre-k and kindergarten students. My elementary school aged bodily-kinesthetic learners also respond well to this technique. Arm blending helps students develop phonemic awareness. Arm blending involves sweeping one arm down the length of the other as words are being pronounced (Fox, 2000). For example: the teacher’s hand starts on his or her shoulders and the student mimics. For the word scrape the teacher says, “S-C-R, S-C-R, /skr/ /skr/ /skr/” and the student echos. Then, the teacher moves their hand to their elbow and says, “A-E, A-E, /ā/ /ā/ /ā/” and the student echos. Afterwards, the teacher moves their hand to their wrist and says, “P, P, /p/ /p/ /p/” and the student echos. Finally, the teacher and student move their hands to their shoulders and say the whole word while moving down to their wrists, “/skr/ ! /ā/ ! /p/ ! scrape!”
