In this video, Mr. J explains how to interpret a line plot that includes fractions such as eighths, fourths, and halves. The line plot represents the growth of 15 plants over one week. Mr. J guides viewers through identifying the lowest and greatest growth amounts, calculating the difference between them, and determining the total growth of all plants. The video emphasizes understanding fractions and using them to analyze data on a line plot.

What does each 'X' on the line plot represent?

• The height of the plant in inches

• The age of each plant in weeks

• The growth of each plant in inches

• The number of leaves on each plant
