Capacity Measuring Liquid A Third Grade Review Customary

Capacity—Measuring Liquid A Third Grade Review!

Customary Capacity • There are 4 main units of customary capacity! • Gallons—Gal • Quarts—Qt • Pints—Pt • Cups--C

Gallons i a n t Gallons are used to measure large amounts.

Quarts Here is a quart of milk.

Pints Mason and Jelly Jars are about a pint.

Cups

Conversions Use the Big G!!

Draw the G for Gallon.

Add 4 Q’s for Quarts.

Go P P at CCs…P’s for Pints, C’s for Cups C C …Then put 2 of these in each quart!

C C

C C C C

Which is more: 3 qt or 4 pt? When I look at the Big G, I see that 4 pt is the same as 2 qt. That means that 3 qt is more than 4 pt.

Try this one: Ms. Itzhaki went to the store to buy 6 quarts of milk. They were out of quarts! She had to get pints instead. How many pints did she need to bring home the same amount of milk? Click the button to see the Big G.

Since 6 qt = 12 pt, she needed to buy 12 pt!

Metric Capacity There are 2 main units of metric capacity. Liters--L Milliliters--m. L

Liters a r g e We measure large things in liters.

A Milliliter is about a drop. A drop of water. An eyedropper of medicine.

Conversions in Metric! 1, 000 m. L = 1 L When converting L to m. L, put 3 zeros in place of the L--that’s multiplying by 1, 000. 2 L = ______ m. L 000 So, 2 L = 2, 000 m. L

4 L = ________ m. L 000 So, 4 L = 4, 000 m. L _____ m. L = 2 L 000 So, 2, 000 m. L = 2 L

Ms. Itzhaki’s water cooler holds 5, 000 m. L of Kool-Aid. She has 2 bottles of Kool-Aid. Each bottle holds 2 L. Will the Kool-Aid fit in her water cooler?

Step One: Draw the picture to show what she has. 2 L + 2 L = 4 L Step Two: Convert to the lower unit--m. L. 4 L = _______ m. L… 000 so 4 L = 4, 000 m. L

Ms. Itzhaki’s water cooler holds 5, 000 m. L of Kool-Aid. She has 2 bottles of Kool-Aid. Each bottle holds 2 L. Will the Kool-Aid fit in her water cooler? Step Three: Answer the Question. YES, since she has 4, 000 m. L of water, it will fit in her 5, 000 m. L container!
