Ohio Resource Center; Stella's Stunners-stimulating math problems

Welcome to the Ohio Resource Center 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.
