This is ONE coloring page for teaching articulation of R! /r/
Print them out and have them on hand.
Compare the easy to see mouths so kids can see how their mouth needs to look to make the R sound.
I hand out the coloring page and ask them to carefully color all the parts: lips, tongue, teeth and air.
Students can repeat the sound as they color, if they can produce it in isolation.
In a group session, I have the kids color in between turns, keeping them busy during wait time.
Once the images are colored, I save them for further sessions so that I can point to specific parts on their drawing to remind them which part of their mouth needs to be adjusted. Students may also take their coloring page or a blank sheet home, to hang up as a reminder to practice, for generalization.
Full page, easy to see and color.
