Using Line Plots to Solve Subtraction Problems

The video tutorial teaches how to solve subtraction problems using line plots. It begins with an introduction to line plots and how to interpret data. The lesson then explains how to subtract fractions, emphasizing common mistakes. Using a practical example, the video demonstrates comparing insect lengths on a line plot and solving the problem by finding the difference. The tutorial concludes by summarizing the key points of using line plots for subtraction.

What does each mark on a line plot represent?
