Take a class tally on how many brothers or sisters each pupil has, and make it into a graph. Ask students how the results of this activity might have been different for their parents and for their grandparents. Ask pupils to list the reasons why Jill has chosen to have fewer children than her ancestors. Why do some people in some parts of the world have more than two children? What would happen if more women took Jill's decision?
