Make a line plot to display a data set of measurements in fractions of a unit

What you'll learn

1. Create a line plot by marking a number line with evenly spaced fractional intervals (halves, fourths, or eighths of a unit) and placing X marks above the values to represent a data set of measurements
2. Choose an appropriate fractional scale for the number line based on the denominators present in the data set - for example, using eighths when the data includes 1/8, 3/8, and 1/2
3. Read and interpret a line plot to answer questions about the data, including identifying the most common measurement, the range, and the number of data points at each value
4. Add fractions from a line plot to solve problems such as "What is the total length of all objects that measured 3/4 inch?"
5. Subtract fractions from a line plot to solve problems such as "How much longer is the longest object than the shortest object?"
6. Multiply a fraction by a whole number using line plot data to solve problems such as "If there are 4 objects that each measure 3/8 inch, what is their combined length?"
