EEK--A Cockroach!
St. Julien, Laurie
Teaching Children Mathematics, v16 n6 p364-371 Feb 2010
Students from thirteen fifth-grade classrooms from six different elementary schools investigate the preferred escape routes of cockroaches. These identified routes of 90-, 120-, 150-, and 180-degrees are the research findings of Paolo Dominici, an Italian scientist. The students used rubber cockroaches and lizards to map out these escape routes. Activities in the "investigations" department regularly highlight development of conceptual understanding for mathematics topics. This multiday investigation had students explore data sets to discover how to find the range, mode, median, and mean and to develop meanings for these terms. (Contains 3 figures.)
