Line Plots

1

Today's big idea

A line plot puts one X above each measured length.

Count the Xs stacked above a length.

2

How it works

👀 What's going on?

Ten pencils are measured. How do you show them all at a glance?

💡 Here's the trick

One X for each pencil length5678length in cm → count the Xs above each

A line plot puts a mark above each measured length on a number line. A taller stack means more of that length.

For lengths 5, 6, 6, 7 cm: put one X above 5, two Xs above 6, and one X above 7.

✍️ Try it

On a plot, 8 cm has 3 Xs. How many pencils are 8 cm long? → 3.

⚠️ Watch out

Each X stands for one thing, so count the Xs, not the number below.
