An excellent resource for apraxia, articulation, and phonology therapy! I use this book at the beginning of all of my speech sessions to allow students to "warm up" their speech sounds. All sounds in this book are arranged from earlier-developing to latest-developing. I typically have students practice the entire book, but you may choose a developmentally appropriate stopping point.
Each target sound is accompanied by a SymbolStix graphic representation (graphics used with permission). This book quickly became a staple for my therapy sessions - I hope you find it to be useful as well!
