Some Low Tech Options

Technology does not always have to be high tech to be effective for differentiating. Check out these great audio tools- Talk Point. They are capable of holding 10 seconds (this is longer than you think) of sound for playback. Can be used for a million different accommodations in the classroom!

Talk Point™, Set of 5 - ESL/ELL - Shop by Category - Teachers - Learning Resources®

Just a few ideas:
pre-record directions for an activity or center
use as a phonics tool for sound discrimination or sound blending activities
use to support struggling writers. Let them record their sentence, then go back and replay as they write the sentence word by word- supports working memory!

Learning resources also sells a similar recording device that is attached to a white board so that you can use for interactive writing activities- a little pricier than just the recorders themselves, but also full of classroom possibilities!
