Third graders learn that a line plot stacks a mark for each data point above a number line, making it easy to see how often each value happens, then check what they know.
Students will be able to…
A class measured their pencils and stacked an X for each one above a number line, and the tallest stack jumps right out. What does a line plot show, and how do you read it?
Project this and answer each question about how a line plot shows data above a number line — read the explanation after each one.
