Max Maths, Year 5, Practice, Changing the scale on the vertical axis (1)

In the Max Maths practice for Year 5, students are given the opportunity to hone their graphing skills through a couple of engaging exercises. The first task involves plotting the cooling of a cup of very hot tea over time. Students are provided with a table of data showing the temperature of the tea at one-minute intervals, starting from 100°C and decreasing to 50°C after six minutes. They are instructed to draw a graph using the given axes, with time in minutes on the horizontal axis and temperature in degrees Celsius on the vertical axis. This exercise helps students understand how to represent data visually and interpret the relationship between time and temperature.

The second exercise presents a scenario where Maya is tracking the growth of her baby boy and has created a line graph to depict his height over time. Students are tasked with examining two given line graphs and identifying which one accurately represents Maya's records by placing a tick next to the correct graph. Both graphs show time in years on the horizontal axis and height in centimeters on the vertical axis, but they differ in how the data is plotted. This activity challenges students to critically evaluate graphical information and reinforces their ability to interpret line graphs, an essential skill in data representation and analysis.
