Problem 1:
The line plot shows distances students live from school (in miles).
We need to find the difference between the student who lives closest and the one who lives furthest.
Look at the marks on the number line:
- The leftmost mark is at
5 → that’s the closest.
- The rightmost mark is at
7 → that’s the furthest.
Difference = 7 - 5 =
2 miles
✔ Answer for #1:
2

Problem 2:
Line plot shows phone heights in inches.
Find difference between shortest and longest phone.
Leftmost mark:
4
Rightmost mark:
5
Difference = 5 - 4 =
1 inch
✔ Answer for #2:
1

Problem 3:
Amount of water drunk (gallons) in a week.
Lowest amount vs highest amount.
Leftmost mark:
0
Rightmost mark:
3
Difference = 3 - 0 =
3 gallons
✔ Answer for #3:
3

Problem 4:
Size of frog species (inches).
Shortest vs longest species.
Leftmost mark:
1
Rightmost mark:
4
Difference = 4 - 1 =
3 inches
✔ Answer for #4:
3

Problem 5:
Length of girls’ hair (feet).
Shortest vs longest hair.
Leftmost mark:
1
Rightmost mark:
3
Difference = 3 - 1 =
2 feet
✔ Answer for #5:
2

Problem 6:
Distance Carol walked each day (miles).
Fewest miles vs most miles in a day.
Leftmost mark:
1
Rightmost mark:
3
Difference = 3 - 1 =
2 miles
✔ Answer for #6:
2
