Drag, manipulate and animate visual mathematics to develop and generalize your understanding of fundamental concepts across elementary math, geometry, algebra, trigonometry, calculus, and beyond. Based on the award-winning software The Geometer's Sketchpad®, the Sketchpad Explorer app allows you to interact with, and investigate, any document created in Sketchpad. With a simple, powerful multitouch interface, Sketchpad Explorer puts mathematical comprehension at your fingertips.

"Welcome to the ORC Stella website. The core of this collection is a library of more than 600 non-routine mathematics problems known as Stella's Stunners to be launched set by set over the coming months. The problems range from simple visual problems, requiring no specific mathematical background, to problems that use the content of Pre-Algebra, Algebra I, Geometry, Algebra II and Trigonometry, up through Pre-Calculus. The Stella problems are not typical textbook exercises. They are considered "non-routine" problems because the methods of attacking them are not immediately obvious. Because these problems can supplement and enliven traditional mathematics courses in a variety of ways, we have included materials to assist in using Stella problems in your teaching: "
