  Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems invo...

01

What Students Need to Do

Students organize fractional measurements on a line plot with a clear scale and labels. They use the plotted values to answer questions with fraction operations.

02

What Mastery Looks Like

A student can build an accurate line plot from measurements in halves, fourths, or eighths. They can explain each mark and use the data to find totals, differences, and equal shares.

03

Common Misconceptions

Students may space fractions unevenly on the number line. They may read the height of a stack as a measurement rather than a frequency. They may add or subtract numerators and denominators separately.

04

How to Assess It

Exit ticket: Plot 3 1/2, 3 3/4, 3 3/4, 4, and 4 1/4 inches on a quarter-inch line plot. Find the difference between the longest and shortest lengths.

1. 01

   Have pairs measure eight classroom objects to the nearest quarter inch, record the lengths, and build a line plot with sticky notes.

2. 02

   Show a line plot and ask, "What claim can you make about the data, and which values support it?"

3. 03

   Play Line Plot Match: students pair data cards with matching plots, then solve a fraction question to keep each pair.

4. 04

   Give students plant-height data in eighth-inch increments and ask how much taller the tallest seedling is than the shortest.
