Study Notes

A line plot is a graph used to count and visualize multiple data points, often used with small groups of numbers.
Line plots are useful for showing how many times something has happened, such as measuring the length of insects.

Start by creating a number line with the unique measurements from the data points (e.g., 1/8, 1/4, 1/6, 1/3, and 1/2).
Represent each data point as an 'X' above its corresponding measurement on the number line.

A line plot allows us to easily see the frequency of each measurement, such as how many bugs are a certain length.

To add the measurements of two bugs together, we need to find a common denominator or least common multiple (LCM) if they don't already share one.
Once we have a common denominator, we can add the fractions together, and simplify the result if possible.

To subtract the measurements of two bugs, we need to find a common denominator or least common multiple (LCM) if they don't already share one.
Once we have a common denominator, we can subtract the fractions, and simplify the result if possible.
