line plot

Definition

A line plot is a simple graph that uses X's or dots above a number line to show how often each number appears in a set of data.

If three kids have 2 pets, you would put three Xs above the number 2 on the line plot.

How to teach this in 30 seconds

Try this analogy: A line plot is like lining up everyone's shoes by size to see how many of each size you have.

Ask your child: Which number has the most Xs stacked above it?

Common mix-up: Kids may think the Xs are just random marks. Each X represents one person or thing, and its position on the line shows its value.

Examples

  • Making a line plot to show how many letters are in each family member's first name.
  • Rolling a die ten times and putting an X on a line plot for each number rolled.

line plot is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
