Third Grade EOG Math Review

Goal 2: Measurement

There is a lot of information that you will need from Goal 2!

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

This slideshow will help review

important concepts that you need to

KNOW for the EOG!

Know it...about length!

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.)

Small objects,

like a crayon

person

Yard (yd)

backyard

Mile (mi)

Distance from

Charlotte to New York

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

tiny objects, like an

eye

book

centimeter (cm.)

decimeter (dm.)

kilometer (km.)

person

meter (m.)

far distances

, like from our school to Walmart

10 centimeters = 1 decimeter

100 centimeters = 1 meter

1,000 meters = 1 kilometer

Use prefixes to help you remember conversions!

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!

Know it…about temperature!

• 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.

Know it..about Fahrenheit!

90 is hot70 is nice50 is cool

And 32 is ice.

The freezing point in Fahrenheit is 32F.

The boiling point in Fahrenheit is 212F.

Know it..about Celsius!

The freezing point in Celsius is 0C.

The boiling point in Celsius is 100C.

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 spotand 40 is just plain hot.

Know it…about capacity!

• 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!

Know it..about customary capacity!

• 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

Know it..about metric capacity!

• 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 1,000 mL = 1 LL

Know it…about elapsed time!

• 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.12

Each large number on a clock represents 5

minutes.

60 minutes = 1 hour60 minutes = 1 hour

Know strategies for calculating elapsed time!

• Draw an analog clock to help you!• Make a table like this:

• Create a timeline.

Know it…about weightweight!

• ““How heavy is it?”How heavy is it?”

• We use two systems to measure weight, or mass—Customary and Metric.

• Scales can be used to measure weight.

Know it…about customary weight!

• There are two units we use in the customary system of weight.

ounces pounds

1 lb = 16 oz.

Know it…about metric weight!

• There are two units we use in the metric system of weight.

grams kilograms

1,000 g= 1 kg

kilo= 1,000
