Ant Smasher is a fun, free App to use as a reinforcer or for teaching kids how to isolate their touch skills on the ipad. A picture comes on the screen, then the ants start coming. Your job is to "smash" the ants by touching them. There is sound too which gives the gross sound of the ants smashing, the kids love this! You can go into the options screen and add photos that you have in your ipad photo file. Kids can then smash the ants on their own face or a classmates. Kids find this highly motivating. I have kids who earn this as a reinforcer at the end of our work task. My students are K-3 in a self-contained DI Classroom. (RK)
