Mathematics, Measurement (includes Time)

Grade 3- 5

Objective

Students learn about comparing and calculating liquid measurements.

Directions

Give students some background information about liquid measurements. They will need this information to complete the activity sheets.
The most common small unit of liquid measurement for daily use is a fluid ounce.

A fluid ounce (fl. oz.) is equal to 6 teaspoons (tsp.) full of liquid.

1 fluid ounce = 6 teaspoons

A fluid ounce is equal to 30 milliliters. An eye dropper holds about 1 milliliter. It would take 30 eye droppers to hold 1 fluid ounce.

1 fluid ounce = 30 milliliters
Cups, Pints, Quarts, and Gallons

• There are 8 fluid ounces in 1 cup. (1 c. = 8 fl. oz.)
• There are 16 fluid ounces in 1 pint. (1 pt. = 16 fl. oz.)
• There are 32 fluid ounces in 1 quart. (1 qt. = 32 fl. oz.)
• There are 128 fluid ounces in 1 gallon. (1 gal. = 128 fl. oz.)
• There are 2 cups in 1 pint. (1 pt. = 2 c.)
• There are 2 pints in 1 quart. (1 qt. = 2 pts.)
• There are 4 quarts in 1 gallon. (1 gal. = 4 qts.)

Distribute the activity sheets to students and have them use what they have learned to complete the activity.
