Bean counting, fog, and snow

In this task, students predict the number of snow days by counting beans in a jar, a Native American method. Each month, elementary school teachers are presented with a problem along with suggested instructional notes; asked to use the problem in their own classrooms; and encouraged to report solutions, strategies, reflections, and misconceptions to the journal audience.
