Look at the household accounts of poor Victorian families (many studies were carried out in the late 1800s and early 1900s) and examine how important children's wages were for survival.
Try to get beyond the stereotypical saintly image (often manufactured by later writers) of the reformers opposing child labour and understand their complex and varied motives by using a range of extracts from their original writings.
Examine the structural factors that caused child labour and look at the stereotypical image of those who supported it. These people are often portrayed as heartless, greedy employers, but opponents also included welfare workers and parents. Examine interviews by Mayhew, Booth and Rowntree to add some complexity to this often over-simplified debate.
