Kavi Picks the Right Tool

Kavi had three jobs to do. First, Kavi wanted a sharp photo of a bird in the garden — so Kavi grabbed the camera, not the calculator. Next, Kavi had to type a long two-page story — so Kavi opened a laptop with a big keyboard, not a tiny phone. Last, Kavi needed to find the way to a new park — so Kavi opened the map app, not the drawing app. "Every job has a best tool," Kavi hooted. "When I match the device or app to the job, the work is quick and easy!"
