If you have or can create a set of tiles, numbered one through eight, then you can implement this hands-on instructional activity about probability models. Individuals draw a tile from a bag, record its number, and then return it to the bag. They predict the probability of the product of three draws equalling an odd number. Teach them how to use sample spaces and tree diagrams to do so. The notes for the instructional activity are fairly simple, but include two assessment questions and an extension suggestion.
