## Ready when they can

- Measure five objects to the nearest 1/4 inch
- Create a line plot showing the lengths of classmates' pencils in half-inches
- Read a line plot and answer questions about the data

## Lesson: Halves and quarters on a line plot

You already know how to measure things and build a line plot. Now you will measure closer: to the nearest half inch, or the nearest quarter inch. A ruler splits every inch into four equal quarter marks: 1/4, 1/2, 3/4, and the whole inch.

*(drawing: Three of the four quarters are shaded. That length is 3/4 inch.)*

**Example.** Five students measured their pencils to the nearest quarter inch: 2 in, 2 1/4 in, 2 1/2 in, 2 1/2 in, and 3 in. For each pencil, they put one X above its length on a number line marked in quarters.

*(drawing: 2 1/2 inches has two X's stacked above it, so it is the most common length in this data.)*

Reading a line plot is counting. Each X stands for one object, so two objects with the same length get two X's stacked on that mark. The tallest stack is the most common length. To find how many more, count both stacks and subtract. Halves and quarters share one scale: 1/2 inch sits where 2/4 inch does.

**Recap.** Measure to the nearest quarter inch, mark an X for each length, and read the tallest stack to find the most common length.
