Interpret Line Plots
π Read the skyline! You didn't paint this picture, but you still have to read the data. Count the X's to find the secrets!
Do this: Read the concept below, then try the quiz or activity.
Concept
A line plot is already drawn. We have to "Interpret" it (which is a fancy science word meaning "understand what it says").
π― How to Read the X's: Imagine a line plot showing "Books Read By Students". * Above the number 1, there are two X's. (This means TWO students read exactly 1 book.) * Above the number 4, there are five X's. (This means FIVE students read exactly 4 books!)
The Magic Questions: * "How many kids read exactly 4 books?" A: Read the height of the column! (5 kids). * "How many kids read MORE than 2 books?" A: Count ALL the X's that are above the numbers 3, 4, 5, etc! You must add them together.

Instructions: Look at the description of the line plot and answer the questions.
Line Plot: "Number of Teeth Lost by 2nd Graders" * Number 1: X X * Number 2: X * Number 3: X X X X * Number 4: X X X
Problem 1: How many students lost exactly 3 teeth? * (Count the X's above the number 3!) * Answer: ___ students.
Problem 2: How many students lost exactly 2 teeth? * Answer: ___ students.
Problem 3: Which amount of lost teeth was the most common in the classroom? * Hint: Find the tallest tower of X's! Which number is it above? * Answer: ___ teeth.
Problem 4 (Brain Bender!): How many kids lost MORE THAN 2 teeth? * (Hint: Count all the X's on number 3, plus all the X's on number 4!) * Answer: ___
