Concept(s): Conversion is the act of obtaining equivalent value, as of money or units of measurement, in an exchange or calculation. Specifically, measurement conversion is the act of obtaining an equivalent measurement. Converting measurements is an important real life skill and is required to compare, order, or perform operations on measurements with different units.

TEKS:

The student is expected to:

4.11(B) performs simple conversions between different units of capacity within the customary measurement system.

Objectives

Evaluation Questions for each Objective

1. Choose an appropriate capacity measure for real life situations.

What the Students Will Do

Place Holiday Party Problem transparency on the overhead.

“I need your help. I am planning a party and I have invited 23 people to the party. I have a punch recipe that makes 1 ½ gallons of punch. I want to serve each person a cup of punch, but I don’t know if there will be enough for everybody. ”

Will I have enough punch for everyone? Why or why not?

-Yes, because 1 ½ gallons seems like a lot

-No, my family can drink a whole gallon of milk and there are a lot less than 23 people in my family.

About how many people do you think I can serve a cup of punch if I make 1 ½ gallons of punch for the party?

Any answer welcome

Students will make predictions about the amount of punch.

What information do you need to know in order to solve this problem?

You need to know how many cups are in a gallon.

Students will discuss the problem with group members and offer suggestions on how to solve the problem.

TRANSITION

We decided we need to know how many cups are in a gallon. In our next activity we will use measuring cups to actually find out how many cups are in a gallon.

What the Students Will Do

Distribute the Mr. Gallon body and limbs to each group.

Have a large pan filled with rice, an empty milk gallon container in the center of the pan, and a quart measuring cup outside the pan.

Hold up the milk container for everyone to see.

Hold up the quart measuring cup.

The teacher will chose a group to check the class’ prediction by the containers and rice.

What is the capacity of the milk container?

1 gallon

Besides milk, what other things might be measured with gallons?

Gasoline

Juice/punch

Amount of water a household

uses in a month

What is the capacity of this measuring cup?

1 quart

How many quarts of rice do you think it will take to fill the empty milk gallon container?

Any answer welcome

Students will make predictions about the number of quarts in a gallon by looking at each of the containers.

Two students will demonstrate how many quarts can fit in a gallon by filling the quart measuring cup with rice and pouring it into the gallon container until it is full. The 3rd student will record the information on the board (1 gallon = 4 quarts). The 4th student will glue the quart parts of Mr. Gallon to the model (the quart parts will be Mr. Gallon’s arms and legs).

The remainder of the class will glue the quart parts of Mr. Gallon to their own models.

The teacher will check for student understanding by asking questions and calling on individual students.

How many gallons are equal to 8 quarts?

2 gallons

How many gallons are equal to 2 quarts?

1/2 gallon

How many quarts are in 3 gallons?

12 quarts

How many quarts are in 10 gallons?

40 quarts

Which is greater: 6 gallons or 20 quarts? Why?

6 gallons because 6 gallons = 24 quarts

Students will use their Mr. Gallon Man models to answer questions.

Hold up gallon and quart containers. “We have seen what a gallon container and a quart container look like.”

Hold up pint measuring cup.

The teacher will chose a group to check the class’ prediction by using the containers and rice.

What is the capacity of this smaller measuring cup?

1 pint

How many pints of rice do you think it will take to fill the quart container?

Any answer welcome

How many pints of rice do you think it will take to fill the empty milk gallon container?

Any answer welcome

If it takes 2 pints of rice to fill up the quart container, how many pints of rice will it take to fill up the gallon?

8 pints

Students will make predictions about the number of pints in a quart or gallon by looking at each of the containers.

A different group of students will repeat the process of using the rice to find out how many pints are in a quart. Two students will pour rice, the 3rd student will record the information on the board (1 quart = 2 pints and 1 gallon = 8 pints), and the 4th student will glue the pint parts of Mr. Gallon to the model (the pint parts will be Mr. Gallon’s lower arms and legs).

The remainder of the class will glue the pint parts of Mr. Gallon to their own models.

The teacher will check for student understanding by asking questions and calling on individual students.

How many gallons are equal to 16 pints?

2 gallons

How many gallons are equal to 4 pints?

1/2 gallon

How many pints are in 5 gallons?

40 pints

How many pints are in 10 gallons?

80 pints

Marta drinks 7 pints of milk a week. Her brother Samuel drinks 4 quarts of milk a week. How much milk should their mother buy each week so there is enough for both Marta and Samuel?

15 pints or 7 ½ quarts or approx 2 gallons

How do you know?

6 pints = 3 quarts which gives you 7 quarts plus 1 pint left over, that pint is the same as ½ quart. Since there are 4 quarts in a gallon, you would need 2 gallons to have enough for Marta and Samuel to drink 7 ½ quarts.

Students will use their Mr. Gallon Man models to answer questions.

Hold up gallon, quart, and pint containers. “We have seen the sizes of 3 measures of capacity: the gallon, the quart, and the pint.”

Hold up the 1 cup measuring cup.

The teacher will chose a group to check the class’ prediction by using the containers and rice.

What is the capacity of the smallest measuring cup?

1 cup

How many cups of rice do you think it will take to fill the pint container?

Any answer welcome

4 cups

If it takes 4 cups of rice to fill up the quart container, how many cups of rice will it take to fill up the gallon?

16 cups

Students will make predictions about the number of cups in a pint, quart or gallon by looking at each of the containers.

A different group of students will repeat the process of using the rice to find out how many cups are in a pint, quart, and gallon. Two students will pour rice, the 3rd student will record the information on the board (2 cups = 1 pint, 4 cups = 1 quart, and 16 cups = 1 gallon), and the 4th student will glue the pint parts of Mr. Gallon to the model (the cup parts will be Mr. Gallon’s fingers and toes).

Student Responses

What the Students Will Do

Say, “We’ve been talking about punch all day and it’s making me thirsty. Let’s make some punch.”

Display the punch recipe transparency. Hide the 1 cup measuring cup.

“Uh oh…it seems like we have lost one of the cups and all we are left with are the pint and the quart measuring cups. The directions are in cups!”

Can we still make the punch?

Yes, by converting the measurements into pints or quarts

How much pineapple juice do we need?

1 pint

How much orange juice do we need?

1 pint

How much water do we need?

6 pints or 3 quarts

How much sugar do we need?

1 pint

How much Sprite do we need?

2 pints or 1 quart

Students will help make punch by providing correct conversions. Select students will measure, pour, and mix ingredients.
