I am always looking for new articulation apps. My new favorite is Articulation Station! This app was created by Heidi over at Mommy Speech Therapy (a blog I LOVE). This app is great because it allows you to customize it. It is a free download that comes with targets for the /p/ sound. From there, you can choose what sounds to download for a price (most around $5). This way you aren't paying $50 for an app when you only need /s/, /r/ and /l/ sounds!
Single word targets
One last thing I like about this app it it allows you to data track students scores in the app. You can have them emailed to you or store them on the app! I hope you find this app as fun and useful as I have. If there are any apps you are loving right now... please share! :)
