Thursday: The leaf collection
Chris the Coyote settles by the campfire ring and opens his satchel.
"Lizzy once measured thirteen leaves from the trail," he says.
"She wrote each length in her notebook."
"Then she drew a number line in fourths of an inch."
"For each leaf, she put an X above its length."
"Soon she could see which length was the most common!"
Learn it: a line plot
A line plot is a number line with an X for each measurement.
Lizzy's line plot counts in fourths of an inch.
Two Xs above a number means two leaves had that length.
The tallest stack is above 1 1/2. It has 4 Xs.
So 4 leaves were 1 1/2 inches long.
