There are many Halloween themed apps that can be used for a large number of speech and language objectives. I don't need to tell you about them as many other SLPs have done a great job on their blogs. AND, a few even created Apptivities - activities to use with the apps.
Check out the list below to find FREE and budget priced apps along with FREE advice as to how to use them.
SPEECH2U posted some of her favorite Halloween apps along with suggestions as to how they can be used at A gazillion Ghoulish Games and Apps. And, her 2012 post, Halloween Masks, tells how she uses the app, Mask Mania and other masks or head gear with a variety of speech and language skills.
At Technology and Speech Therapy Corner, Heather Strebel, posted a FREE printable barrier game activity to be used with the app Monster Mash Lite.
At Speech/Language? There's an App for That and More!, Jenny C. tells about some Halloween apps and goes into detail about how she uses them in therapy. One of her favorite apps, Henry's Spooky Headlamp, is also one of mine.
