Each month, elementary school teachers are given 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. This month, students are asked to count and organize a large collection of candies to promote an understanding of place value in our base-ten number system.
