Final answer:
Aztec children were likely punctual to school because of the strict discipline in Aztec society, where tardiness was severely punished, ensuring that values such as punctuality and responsibility were instilled from a young age.
Step-by-step explanation:
Aztec children would not be late to or miss school primarily because of the strict discipline and consequences associated with tardiness in the Aztec education system. Aztec warriors were trained from childhood to be disciplined and punctual, a trait that permeated their society, including the education of the youth as depicted in the Codex Mendoza (c. 1542). Schooling in the Aztec society served not only as an institution for learning but also for instilling societal norms and preparing the next generation for their roles in the community, whether as traders, midwives, healers, or wilital leaders. Punishment for being late or absent without cause was likely severe, helping to ensure that children understood the importance of education and obligation.
