### Third Grade EOG Math Review

Goal 2: Measurement

• This goal covers:
• Length
• Elapsed Time
• Weight
• Capacity
• Temperature

This slideshow will help review important concepts that you need to KNOW for the EOG!

When we are measuring length, we are trying to figure out how long an object is.

There are two systems of length that we use to determine length--- the Customary System and the Metric System.

Customary Length

Inch (in.)

Foot (ft.)

Yard (yd)

Mile (mi)

Distance from Charlotte to New York

person

Small objects, like a crayon

backyard

Customary Conversion Chart

12 inches = 1 foot

36 inches = 1 yard

3 feet = 1 yard

1,760 yards = 1 mile

5,280 feet = 1 mile

Know appropriate measures for distances!
• Measure small objects using inches, such as erasers and books.
• If it’s as big as you are, use feet!
• If it is as big as your backyard, use yards!
• Miles measures the most distance.. You go far in your car!
Metric Length

centimeter (cm.)

decimeter (dm.)

kilometer

(km.)

meter

(m.)

far distances, like from our school to Walmart

book

person

tiny objects, like an eye

Metric Conversion Chart

10 centimeters = 1 decimeter

100 centimeters = 1 meter

1,000 meters = 1 kilometer

Know appropriate measures for distances!
• Measure small objects using centimeters, such as erasers and books.
• If it is as big as your backyard, use meters!
• Kilometers measures the most distance.. You go far in your car!
• Temperature answers the question, “How warm?”
• We use thermometers to measure temperature.
• There are 2 scales that we use to measure temperature—Fahrenheit and Celsius.
• Temperature is measured in degrees.

90 is hot

70 is nice

50 is cool

And 32 is ice.

The freezing point in Fahrenheit is 32F.

The boiling point in Fahrenheit is 212F.

Count by tens and you will see,

Celsius is so easy!

0 is freezing, 10 is just cool,

20 is the temperature of most

rooms at school,

30 is quite a warm spot

and 40 is just plain hot.

The freezing point in Celsius is 0C.

The boiling point in Celsius is 100C.

• Capacity tells the amount a container can hold.
• Capacity can be measured using measuring cups or measuring spoons.
• There are 2 systems we use to measure capacity---customary and metric!
• There are 4 main units of customary capacity!
• Gallons—Gal
• Quarts—Qt
• Pints—Pt
• Cups--C

Use the “Big G” to help with conversions!
• 2 cups = 1 pint
• 2 pints = 1 quart
• 4 quarts = 1 gallon
• 8 pints = 1 gallon
• 16 cups = 1 gallon
• There are 2 main units of customary capacity!
• Liter– L
• Milliliter-- mL

A milliliter is about a drop.

There are 1,000 milliliters in one liter.

1,000 mL = 1 L

• Elapsed time describes the passing of time.
• It answers the question: How much time has passed?
• Knowing how to tell time is a MUST for calculating elapsed time.

Each large number on a clock represents 5 minutes.

60 minutes = 1 hour

Know strategies for calculating elapsed time!
• Make a table like this:
• Create a timeline.
• “How heavy is it?”
• We use two systems to measure weight, or mass—Customary and Metric.
• Scales can be used to measure weight.
• There are two units we use in the customary system of weight.

ounces

pounds

1 lb = 16 oz.
