# Organize and interpret numerical data by creating a line plot

Big Ideas: "What" we want to measure affects "how" we measure and display data. Data displays describe and represent data in alternative ways. Data on a line plot is displayed in order due to its scale (similar to a number line). Understand that the ‘shape’ of the line plot graph shows features of the data such as a group. This lesson builds on the students' work with collecting and representing data. While students have typically had experiences sorting information and collections into categories, they are likely to have had fewer experiences with sorting a collection of amounts (or numerical data). The task uses the scenario of a boy, Keaton, noticing plants have more leaves as they grow. Students are asked to generate "leaf data" for 6 plants and create a display to represent their collection. While criteria and representations are suggested, students will use the debrief to discuss the importance of common conventions of a line plot such as scale and labels. In the final task, students are asked to work together to create a class display from sticky notes and a number line. They will use this display to discover a new representation called a line plot. The mathematical concepts in this lesson build toward students' future work with generating measurement data and representing the data on line plots using a scale that is marked off with whole numbers, halves, or quarters.
