Apple Orchard Race (Ready, Freddy! #20) by Abby Klein
Freddy Thresher's first grade class is going on a field trip to the local apple orchard. They get to pick apples, drink cider, and best of all, search for a special wooden apple hidden somewhere in the orchard. Whoever finds it wins $5--but can Freddy get there before Max cheats his way to the prize?
