Statistics - Line graph problems - Worksheet

The "Line Graph Problems" worksheet, tailored for students, focuses on enhancing their ability to interpret line graphs and utilise them to solve various problems. The National Curriculum objective for this lesson is to help children understand how to read line graphs and apply this knowledge to problem-solving scenarios. To facilitate learning, differentiated sheets and teaching slides are provided as resources. The key vocabulary for the lesson includes terms like graph, line graph, data, x-axis, y-axis, reading data, interpreting data, scales, and intervals. Students are expected to have a firm grasp of these concepts, along with the ability to read and draw line graphs accurately.

During the lesson, children will be challenged with questions that prompt them to explore the nuances of line graphs, such as the scale on the vertical axis and its potential to be misleading. They will discuss alternative scales and the clarity of information organisation. The exercises will involve reading information from graphs with varying degrees of marks on the axes, from fully marked to sporadic marks. Through this process, students will learn to discern the relationship between the area of rectangles and right-angled triangles, and apply formulas to calculate areas. The activities are designed to cater to different levels of proficiency, from working towards expected standards to achieving greater depth in understanding and applying the concepts of area measurement.
