SLP Kim Lewis offers up a dotty idea to help kids work on the dreaded /r/ sound (among others): dot-to-dot drawings. By selecting certain images to create, the children become more engaged in trying out their sounds.

She uses a dot-to-dot sheet "that works with your target word (eg., "fairy," (the dreaded) "squirrel," "leaf"). I find great basic sheets at Color Mountain. I also love the Buki activity books. They have dot-to-dots for 1 to 10, others for 1 to 15 and still others with an alphabet series. Use the highlighter to hi ghlight dots every 4-6 spaces apart. As the child completes the puzzles, ask them to say the target word when they pass through the highlighted dot. For a slight increase in difficulty, you can have the child count, too."
