Max Maths, Year 5, Try it, Changing the scale on the vertical axis (2)
Maths Resource Description
In a Year 5 mathematics lesson focused on interpreting line graphs, students are presented with a graph that tracks a person's mass over different ages. The graph is a straightforward line graph with 'Mass in kilograms' plotted on the vertical axis and 'Age in years' on the horizontal axis. The range of the mass is from 0 to 80 kilograms, while the age range is from 0 to 45 years. The students are tasked with a series of questions that require them to analyse the graph and extract specific information regarding changes in the person's mass over time.
The questions serve as a practical exercise for students to apply their understanding of how to read a line graph. They must identify at what age the person was heaviest, calculate the mass gained between 5 and 10 years of age, and determine during which age periods the person's mass remained constant. Additionally, they are asked to find the age at which the person had a mass of 60 kilograms, decide whether there was an increase or decrease in mass between the ages of 35 and 40, and establish the mode mass of the person from the given data. These exercises challenge the students to engage with the graph in a variety of ways, helping to deepen their comprehension of data representation and analysis.
