Max Maths, Year 5, Learn together, Reading and constructing graphs (1)

In a Year 5 mathematics lesson on reading and constructing graphs, students are introduced to interpreting line graphs through the context of temperature changes in Dubai over the course of a day. The lesson begins by presenting a line graph that plots the temperature against different times of the day, with temperature on the vertical axis and time on the horizontal axis. The graph provides a visual representation of how the temperature varies from the early hours of the morning to the afternoon. Students are encouraged to extract information from the graph, such as identifying specific temperatures at given times and determining when the temperature was at its lowest.

To illustrate how to read the graph, the lesson provides step-by-step instructions. For example, to find the temperature at 11 a.m., students are guided to trace a vertical line from the 11 a.m. mark on the horizontal axis until it intersects with the graph, and then to follow a horizontal line from this point to the temperature scale. This process reveals that the temperature at 11 a.m. is 27°C. Additionally, students learn to pinpoint the time when the temperature is at its lowest by observing the graph for the lowest point, which is indicated by 20°C. By tracing downward from this point, it is determined that the lowest temperature occurs at both 4 a.m. and 5 a.m. These practical exercises in graph reading equip students with the skills to interpret and construct their own graphs, a fundamental aspect of data handling in mathematics.
