Understanding how to read, create, and choose appropriate graphs is a key part of teaching mathematics in elementary education. This skill helps students analyze and communicate data effectively.
1. Interpreting Various Displays of Data
Students should learn how to understand information presented in different types of data displays. Each display type has a specific use and provides unique insights into the data.
- Boxplots (Box-and-Whisker Plots) These display the spread and center of a data set. They show the minimum, maximum, median, and quartiles. Example: A boxplot showing students' test scores can help identify who scored in the middle range, and whether any scores are much higher or lower than the rest.

- Histograms These are used for continuous numerical data grouped into intervals (called bins). Each bar represents the frequency of values within that interval. Example: A histogram showing the number of students who scored within certain score ranges on a math test (e.g., 60–69, 70–79, etc.).
