In this month's problem, students are presented with a scenario in which two friends are planning a summer vacation. The students must use measurement concepts to compare two lakes to determine what bigger means with respect to the lakes and which of the two lakes is bigger. Each month, elementary school teachers receive a problem along with suggested instructional notes and are asked to use the problem in their own classrooms and submit solutions, strategies, reflections, and misconceptions to the journal audience.
