In the last lesson, you learned about line plots.
In this lesson, we're going to explore line plots with fractions.
A line plot is a graph that uses X's to show the number of times a response appears in a set of data.
X's are placed above the number line.
Tip: Line plots are not the same as line graphs.
Let's say Ms. Diaz asked her students about how much time they spent reading each week.
Here are the results.
For us to read this line plot well, let's do a little review of fractions.
Fractions show us parts of a whole.
If this fraction was a pie, it would look like this.
The shaded parts represent 3/4.
The number of X's above a fraction or whole number tell us how many people chose that response.
So let's read this line plot.
How many students read 1 hour per week?
We count the X's above the number 1.
How many are there?
Yes, there are 6.
That means 6 students read 1 hour per week. ✅
How many students read 1 3/4 of an hour?
Look at the point where we marked 1 3/4.
Now count the X's above it.
We see that there's only 1 X above it.
This means only 1 person reads for 1 3/4 hours each week.
How many students read for 1/2 hour per week?
It doesn't seem like there's 1/2 in our line plot.
Do you remember which fraction is equivalent to 1/2?
Yes, 2/4 is equivalent to 1/2.
There are 3 X's above 2/4.
This means 3 people spent 1/2 hour reading every week.
Fantastic job reading line plots with fractions.
Now, try the practice.
