Today’s lesson focused on line graphs, a tool used to represent data over time. Students learned about the components of a line graph, including the title, x-axis (which shows categories like days), and y-axis (which shows quantities like the number of items sold). The lesson explained how to read line graphs by examining points that reflect data changes, such as tracking cookie sales over a week or the growth of a drama club over the years. Understanding line graphs can help students visualize trends and make informed decisions based on data.
