Statistics - Use Line Graphs to Solve Problems - Presentation

In a series of educational slides, students are guided through the process of solving problems using line graphs. The lesson begins with a review of key concepts such as comparison, sum, and difference, which are essential for interpreting data. Students are then presented with line graphs depicting various scenarios, such as overnight temperature changes and heart rate during exercise. They are encouraged to draw vertical and horizontal lines to aid in accurately reading the graph and to use this information to answer questions about highest and lowest values, times of occurrence, and the differences between them.

Further activities challenge students to plan and conduct their own experiments, such as measuring heart rate, and record their findings on a line graph. They must consider how to accurately estimate values at specific times and understand the significance of changes in the data. Additionally, students are tasked with creating stories to explain the data represented in the graphs, such as the filling and emptying of a bath, which helps to contextualise their learning. The lesson encourages discussion and reasoning, prompting students to think about how to gather and present data, and the importance of labelling and measuring units on their graphs.
