Practice grids just might be your new favorite articulation therapy resource, especially when your students are working at the word level. They are great as a motivation tool (add stickers to the boxes) as well as a data collection resource. You can use them in your sessions or send them home for practice. I love to keep them hole-punched and in my binder so they are always handy.
Included are 2 practice grid pages for each sound position: initial /s/, medial /s/, and final /s/.
