In this month's problem scenario, students are presented with a task that connects the leveling concept of the mean and the procedure for calculating the mean. In the context of planning a party, students must help a group of friends determine how to redistribute the money spent so that each friend contributes the same amount to planning the party. Each month, elementary school teachers receive a problem along with suggested instructional notes. Teachers are asked to use the problem in their own classrooms and report solutions, strategies, reflections, and misconceptions to the journal audience.
