Suggestions could be made to assist students in efficiently collecting data. Simply collect and record data. Discuss proper ways to conduct surveys. Use one group to do a demonstration survey within your classroom. Make arrangements with teachers for students to survey their classes.
Students survey assigned class.
If a group has trouble locating their assigned class, ask them to return immediately for your assistance. Discuss the results. Ask students to try to think of other questions. Use calculators if needed. A large wall bar graph may be ideal for displaying this data.
