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 todetermine length--- the Customary System and the Metric System.
Customary LengthInch (in.) Foot (ft.) Yard (yd) Mile (mi) Distance Small person backyard fromobjects, Charlotte like a to Newcrayon York
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 Lengthcentimeter decimeter kilometer (cm.) (dm.) meter (km.) (m.) far distances book , like person from our tiny school to objects, Walmart like an eye
10 centimeters = 1 decimeter100 centimeters = 1 meter1,000 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 hot 70 is nice 50 is cool And 32 is ice.The freezing point in Fahrenheit is 32F. The boiling point in Fahrenheit is 212F.
Know it..about Celsius! 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 0C. The boiling point in Celsius is 100C.
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 withG conversions!QQ P P CC CC • 2 cups = 1 pint PCC P CC • • 2 pints = 1 quart 4 quarts = 1 gallonQQ P P CC CC • 8 pints = 1 gallon • 16 cups = 1 gallon PCC P CC
Know it..about metric capacity! • There are 2 main units of customary capacity! • Liter– L • Milliliter-- mLA milliliter is about a drop. There are 1,000 milliliters in one liter. 1,000 mL = 1
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 11 1 clock represents 5 10 2 minutes. 9 3 860 minutes = 1 hour 4 7 5 6
Know strategies for calculating elapsed time!• Draw an analog clock to help you!• Make a table like this: Activity Start End Elapsed Time Time Time• Create a timeline.
Know it…about weight! weight• “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. nces pou ou nd s 1 lb = 16 oz.
Know it…about metric weight!• There are two units we use in the metric system of weight. ams kilo gr gram s 1,000 g= 1 kgkilo= 1,000
