Use only two computers for this task. Glassford posts questions at each computer. Students finish entering data into database. Cooperative learning groups and then whole-class use mode to discuss categorical data on graphs. Cooperative learning groups and then whole-class use mode, median, and range to describe numerical data on graphs.
Students write definitions for mode, median, and range.
Record corresponding data. Glassford distributes database file to students. On print-out of sorted data, students draw a red line between first field categories and shade in second and third field categories with colored pencils. Students construct Venn diagrams to represent data from database sort. Use buddy class data and corresponding data for own class.
