Have you ever wondered why 6 – -2 = 6 + +2? Is there any such number as negative zero? What percentage of second graders do you think could solve 3 – 5 = c, and how might they solve that problem?
Dr. Jessica Bishop, a UGA mathematics educator, and her colleagues Drs. Lisa Lamb and Randy Philipp at San Diego State University asked themselves these questions and have found surprising answers from their research on children’s mathematical thinking in K–12 classrooms. The three mathematics educators were awarded a 3-year grant from the National Science Foundation to study students’ ways of reasoning about negative numbers in Grades 2, 4, 7, and 11. The purpose of their research is to analyze students’ conceptions of integers and map possible developmental trajectories of students’ integer reasoning. They have conducted over 250 interviews with K-12 students as part of the work of the grant.
Project Z is a collaboration between mathematics education researchers at the University of Georgia and San Diego State University.
