Share equally.The big ideaAdd the eighths, then share them. Smaller parts when it will not split.
How it works
Add the eighths, then share them. Use smaller parts when it won't split.
A line plot can show how much liquid is in each glass.
Sharing equally means dividing the total by the number of glasses.
Example 1: Share equally
- Two glasses hold 1/8 and 5/8 of a liter of milk.
- Add them: 1/8 + 5/8 = 6/8.
- Share between 2 glasses: 6/8 ÷ 2 = 3/8 each.
Example 2: Count the X's
- Each X on a line plot is one glass.
- Add the amounts they show.
- Then share equally.
Example 3: Cut smaller
- A total of 7/8 shared among 2 needs smaller parts.
- Cut each eighth in half to get sixteenths: 14/16.
- 14/16 ÷ 2 = 7/16 each.

- line plot
- A number line with X's for each measurement.
