My computer lab was occupied this past week due to Fort Cherry's Science Olympiad. The 4 iPads and I became a mobile lab for two days in the K-3rd grade classrooms. I was able to enter the classrooms and put the students into groups of four or five. For 30 minutes the students were able to explore different educational apps together. In four hours and 30 minutes these iPads were used by 184 students! Check out some of their favorite applications they used throughout the day.
