Each group of students can use the Spinner Experiments Table for that. The Probability and Geometry discussion shows that sometimes knowledge of geometry is required to answer probability questions. Using spinners, physical or virtual, from the Spinner Game and the Adjustable Spinner Game , groups of students can discuss how to find the exact probability of selecting each sector on their spinner, and then compare their findings with experimental data from the Spinner Game. The Polyhedra discussion connects probability and geometry through construction of dice with various numbers of sides. We can loosely call a die a 3-D object that can land in several different ways when it is rolled on a flat surface.
Most people are familiar with six-sided dice.
Each vertex of the die has the same number of sides connected to it. In practice, you can start from forming one vertex out of several polygons. Then attach the same number of sides to the remaining vertices, finishing the polyhedron. The dice that can be constructed this way are called platonic solids. This lesson can be rearranged in several ways.
