Description: "Open middle" problems, hints, and answers, all aligned to the Common Core State Standards (CCSS). Introduced by Dan Meyer, these kinds of math challenges have a "closed beginning," meaning that they all start with the same initial problem; a "closed end," meaning that they all end with the same answer; but an "open middle," meaning that there are multiple ways to approach and ultimately solve the problem.
