Third Grade EOG Math Review
Goal 2: Measurement
![Page 2: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/2.jpg)
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!
![Page 3: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/3.jpg)
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
![Page 5: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/5.jpg)
12 inches = 1 foot
36 inches = 1 yard
3 feet = 1 yard
1,760 yards = 1 mile
5,280 feet = 1 mile
![Page 6: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/6.jpg)
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!
![Page 9: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/9.jpg)
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!
![Page 10: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/10.jpg)
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.
![Page 11: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/11.jpg)
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.
![Page 12: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/12.jpg)
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!
![Page 14: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/14.jpg)
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
![Page 16: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/16.jpg)
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.
![Page 20: Third Grade EOG Math Review](https://reader038.vdocument.in/reader038/viewer/2022110404/56812dd3550346895d9319ed/html5/thumbnails/20.jpg)
Know it…about customary weight!
• There are two units we use in the customary system of weight.
ounces pounds
1 lb = 16 oz.
