Learning Scenario: Lemonade Stand Capacity

The Challenge:

You're running a lemonade stand! You have a small pitcher that holds 2 cups of lemonade and a large pitcher that holds 1 quart. How many cups are in the large pitcher? Which pitcher holds more lemonade?

Lemonade Stand Challenge

Capacity Conversion:

Small pitcher: 2 cups = 1 pint

Large pitcher: 1 quart = 2 pints = 4 cups

Large pitcher holds more (4 cups > 2 cups)

Check: 1 quart = 4 cups ✓

Capacity Units Guide

Capacity Units:

Cup (c)

Smallest unit for measuring capacity

Example: A coffee mug holds 1 cup

Pint (pt)

2 cups = 1 pint

Example: A small milk carton holds 1 pint

Quart (qt)

2 pints = 4 cups = 1 quart

Example: A large milk carton holds 1 quart

Gallon (gal)

4 quarts = 8 pints = 16 cups = 1 gallon

Example: A milk jug holds 1 gallon

Capacity Examples:

Small containers

Coffee mug: 1 cup

Small pitcher: 2 cups = 1 pint

Medium containers

Large pitcher: 4 cups = 1 quart

Soup pot: 8 cups = 2 quarts

Large containers

Milk jug: 16 cups = 1 gallon

Water cooler: 32 cups = 2 gallons

Practice Examples

Lemonade Stand Problems:

Small pitcher: 2 cups = 1 pint

Large pitcher: 1 quart = 4 cups

Gallon jug: 16 cups = 1 gallon

Half gallon: 8 cups = 2 quarts

Capacity Conversions:

1 gallon = 4 quarts = 8 pints = 16 cups

2 quarts = 4 pints = 8 cups

3 pints = 6 cups

1 quart = 2 pints = 4 cups
