Justin and Jenny, grade 12 math students, walk with their preschool friends Sean and Meg to the local grocery store. There, two classmates are tending the cash registers. The six of them, along with others, are participating in an in-school "field trip" to Consumer Town, located in the South Windsor High School front lobby. The field trip is part of a project that the consumer math and child development classes developed for the preschool children attending the high school's Learning Center. The grocery store they visit is only four feet tall, with cardboard walls. Instead of actual pretzels and apples, the store displays pictures of the various products it offers. Throughout the Consumer Town experience, all learned from each other--the child development students, observing and helping the young children, learned how children learn best. The preschool children learned about numbers and money with help from the high school students. The high school students all learned about different ways to work with children by observing one another's interactions with the preschoolers. The teachers learned how this experience affected the students and considered ways to improve it the following year.
