Statistics - Introducing line graphs - Worksheet

The worksheet titled "Introducing Line Graphs" aims to enhance children's understanding of line graphs as a representation of continuous data. In the exercises, students are tasked with filling in a table based on a given rule and subsequently drawing a line graph that corresponds to the data they have compiled. For example, one activity involves Class 4 observing the growth of a plant over seven weeks, with measurements provided for each week. The students must then represent this data visually by creating a line graph. Similarly, another activity requires students to track the division of amoeba over a period of seven hours, noting the changing quantities, and then plotting these changes on a line graph.

Additional exercises on the worksheet further develop the students' skills in interpreting and plotting data. One scenario presents Class 4 measuring the temperature of a drink every minute for eight minutes, with the temperature increasing by 2°C each minute for the first four minutes and decreasing by 3°C each minute for the last four. The students are instructed to complete the table with these temperature changes and then create a line graph to depict the fluctuating temperatures over time. These activities are designed to build fluency and precision in using line graphs, allowing students to apply their knowledge to various real-life situations and datasets.
