OBJECTIVE: Students will be able to identify units of capacity and equivalent units of capacity.
AIM: How can we use a table of equivalent units to help us convert to units of equivalent capacity?
STANDARDS: 6.M.2, 6.M.3, 6.M.4, 6.M.5
PRIOR KNOWLEDGE: How many words can Maria type in 4 minutes if she types 30 words per minute?

2. MINI LESSON
Capacity is the amount of liquid that a container, like a bottle, can hold.
Capacity can be measured in customary units:
cup the size of an ordinary cup, like a cup of coffee
pint the size of a small carton of milk or juice
quart the size of a larger carton of milk
gallon the size of a jug of milk or juice

3. 1 pint = 2 cups 1 quart 2 pints 1 gallon 4 quarts
EQUIVALENT UNITS OF CAPACITY
1 pint =
2 cups
1 quart
2 pints
1 gallon
4 quarts
Delia bought 16 pints of milk. How many gallon containers could she have bought to have the same amount of milk?

4. Step 1 Convert pints to quarts
Since 2 pints = 1 quart, then 16 pints = 8 quarts
Step 2 Convert quarts to gallons
Since 4 quarts = 1 gallon, then 8 quarts = 2 gallons
Delia could have bought 2 gallons of milk instead of 16 pints

5. Another way:
Since we are going from a smaller measure to a larger measure, we divide.
Remember:

6. Small Large Divide
Pints Quarts Gallons

Capacity can be measured in METRIC UNITS, also.
milliliter (mL) the size of a drop of water
liter (L) the size that is
a little more than
quart
