Max Maths, Year 5, Learn together, Reading and constructing graphs (6)

Max Maths Year 5 provides a comprehensive exercise on reading and constructing graphs, with a focus on understanding the growth of Jade's plant over time. In part (a), students are tasked with determining the height of the plant after three months. To find the answer, they are instructed to trace a vertical line from the 3-month mark until it intersects with a blue dot on the graph, and then to draw a horizontal line from the dot to the height axis. This method reveals that Jade's plant was 14 cm tall after three months. This practical application of graph reading helps students visualise and interpret data accurately.

Part (b) of the exercise asks students to calculate how long it took for the plant to reach 6 cm in height. By following a horizontal line from the 6 cm mark on the graph until it meets a blue dot, and then drawing a vertical line down to the time axis, students can see that it took one month for the plant to grow to 6 cm. In part (c), students learn to measure growth over a period by comparing the plant's height at the start and after four months, finding that the plant grew 16 cm during this time. Lastly, part (d) challenges students to determine when the plant stopped growing by observing that the last three points on the graph are aligned horizontally, indicating no further increase in height. The plant's growth ceased after six months. These exercises not only teach graph reading skills but also how to analyse and interpret data to draw conclusions about real-world situations.
