Representing data on graphs makes math visual and involves some creativity and design. Plotting data using fractional units takes their learning one step further. Also in this unit, students learn to measure using both traditional units (like inches, feet and yards) and metric units, and how to convert measurements within each system. The concept of measurement gets two dimensional when students explore measuring and working with angles.
Understanding data and graphs is a critical skill that we use on a regular basis to read news articles, reports and other media to interpret information. In this unit, students investigate data collection, data organization and visual representation in different kinds of graphics (i.e. line plots, pie charts). Learners also apply concepts of probability and statistics to analyze data.
Similar to learning how to make bar graphs, line plots differ in that they train students how to observe emerging patterns in the data they are assessing. Teaching line plots helps students spot changes over time, useful when learning or reinforcing skip counting. The following activities and worksheets help students gain insight into line plots by providing real life examples of how to plot data.
