The Complete Kit is perfect for the speech pathologist who wants to begin with 1 or 2 students. The Kit includes 2 Bite-Rs with Cases, 1 Practice Deck, 1 Manual, 1 Instruction Booklet, and a Charting Form. The Practice Deck provides a list of 30 functional words that contain R in a variety of positions and contexts (vowels, blends, consonantal) and the common misarticulations for each word with instructions for remediation. Honestly, you don't need to add words since the use of functional words usually generates spontaneous carryover. The Manual includes a chapter specifically on vowels and a chapter that goes in depth with those children who don't make successful productions right away.All kits come with a certificate for free live online training.
