Creating a Line Plot to Show Measurement Data with Fractions

This lesson teaches how to represent data in fractional amounts using a line plot. It begins with an introduction to fractions and line plots, followed by a detailed guide on creating a number line that includes whole numbers and fractions. The lesson then explains how to plot data points on the line plot using student height data as an example. Finally, it discusses analyzing the plotted data, highlighting differences in height between boys and girls. The lesson emphasizes understanding fractional data representation and interpretation through line plots.

What is a line plot used for?

• To show data in fractional amounts

• To compare two different data sets

• To measure the length of objects

• To calculate the average of numbers

When creating a line plot, what is the first step?

• Labeling the horizontal axis

• Collecting the data

• Drawing vertical lines

• Plotting the data points

What is the largest number on the horizontal axis of the line plot?

• 40

• 39 and 1/2

• 38 and 3/4

• 40 and 1/4

How do you represent a data point on a line plot?

• By drawing a circle

• By placing an X or picture

• By writing the number

• By shading the area

Why is it okay to have empty spaces on a line plot?

• Because it shows only the data collected

• Because it helps in better visualization

• Because it means the data is incomplete

• Because it indicates errors in data

What is the range of the boys' heights in the data set?

• 39 and 1/2 inches to 40 and 1/4 inches

• 35 inches to 37 inches

• 38 inches to 40 inches

• 36 inches to 38 and 1/4 inches

What conclusion can be drawn about the heights of the girls compared to the boys?

• The boys' heights are more varied

• The girls are shorter than the boys

• The girls are taller than the boys

• The girls and boys are of the same height
