内容提要：
Ever wonder how to put a new spin on a difficult middle grades math concept like surface area? Look no further! This unique tale takes the reader up to the North Pole and describes how Santa challenges his top elf, Snips Cleaver, to conserve paper because the North Pole is "going green." The elves fill out an application, sing about the area of a triangle, and celebrate the accomplishments of their friends. Jump in and join the adventure with Snips, Hex, Jenn, Mikey, and a host of other elves as they discover that there is usually more than one way to solve a problem.
