Darrin Johnson, principal at Fox Hollow Elementary School in Lehi, recently gave a seminar at the Alpine School District's Administrator Conference titled "Must-Have iPad Apps." Here is a list of some apps he recommends for younger students to help fire up their minds before they head back to school. Additionally, we've added a few more for older students. You can access them from either the iTunes App Store for iOS devices or the Google Play Store for Android devices.
