Line Plots and Data Interpretation

This lesson covers adding and subtracting fractions using line plots. It explains how to interpret data from line plots, calculate differences between data points, and understand the vocabulary associated with line plots. Practical examples using earthworm lengths are provided, along with non-examples to clarify the concept. The lesson concludes with a summary of key points.
