# Conversion

**Wednesday 10/22/08**

### Do-Now: Coin Conversions

- Suppose that you have six quarters. How many is that of...

a) ... pennies?

b) ... nickels?

c) ... dimes?

### I can convert a measurement into different units

- In order to convert a measurement into different units, I need to know...

- We will work together as a class to figure out how many of one liquid measure are equal to another. Record below what we find out.

1 gallon = ` ` quarts | 1 quart = ` ` pints | 1 pint = ` ` cups |
---|

### Using conversion rates for liquid measures

- How many cups are there in a gallon?

- For the blue tupperware we are using in class...

a) How much does it hold in cups?

b) Show below how to convert some of those cups into bigger units.

### Conversion cards game

Use the conversion cards to find the answer to each of the following:

- 1 cup, 1 pint, and 1 quart in cups =

- 3 cups, 2 pints, and 2 quarts in cups =

- 2 cups, 3 pints, and 1 quart in pints =

- 4 cups, 1 pint, and 2 quarts in pints =

- 8 cups, 2 pints, and 1 quart in quarts =

- 2 cups, 3 pints, and 3 quarts in quarts =

- 6 cups, 1 pint, and 2 quarts in gallons =

- 5 quarts, 5 pints, and 2 cups in gallons =

# Conversion Practice

### How many cups is that?

*Please record your work mathematically. For example, you might write:*

`3 pints + 2 quart = 7 pints = 14 cups`

You will not get credit for just an answer.- If I have three pints, how many cups is that?

- If I have two quarts, how many cups is that?

- If I have a pint and two quarts, how many cups is that?

- If I have three cups, two pints, and one quart, how many cups is that all together?

- How many cups is one gallon?

### How can I use the least units?

*Please record your work mathematically. For example, you might write:*

`11 cups = 1 cup + 5 pints = 1 cup + 1 pint + 2 quarts`

You will not get credit for just an answer.- If I have to measure out 8 cups, how can I do that using the least number of units?

- If I have to measure out 7 cups, how can I do that using the least number of units?

- If I have to measure out 13 cups, how can I do that using the least number of units?

- If I have to measure out 27 cups, how can I do that using the least number of units?
