Rich mathematical tasks—here, finding and categorizing the quadrilaterals that can be made with vertices on a 4×4 grid—can promote adaptability in any classroom.
Joe Garofalo and Christine P. Trinter
Students think resiliently about using the quadratic formula, analyzing factors graphically, finding the shortest distance between two points, and finding margin of error.
